- Introduction: This study aimed to determine whether day-case closure of loop ileostomy with discharge within 23 h was both feasible and accepted by patients.Materials and methods: We conducted a prospective pilot study where selected rectal cancer patients with diverting loop ileostomy underwent stoma closure in a 23-h stay setting. Patients were followed up on the third, seventh, and 30th postoperative day and phoned daily during the first week. A comparable group of 30 patients who underwent standard in-hospital stoma closure prior to the start of the study were selected retrospectively as historical controls.Results: In total, 30 patients (median age, 67 years; range, 41-79 years) were included. All patients met discharge criteria and were discharged within 23 h of surgery, except one. In total, seven patients (23%) were admitted. Two of these patients underwent laparotomy because of anastomotic leakage and small bowel obstruction, respectively. The mean total length of stay was 1.7 days. Most patients (87%) were satisfied with the treatment without feeling neglected or anxious and preferred the 23-h stay setting. In the control group, the mean length of stay was 5 days. Seven patients (23%) were readmitted. Two of these patients underwent laparotomy because of small bowel obstruction and abscess, respectively.Conclusion: Ileostomy closure in a 23-h stay setting in selected patients with meticulous follow up is feasible and safe with high patient satisfaction.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: The aim was to identify patient-, tumor- and treatment-related prognostic factors for five-year survival in rectal cancer patients with synchronous stage IV disease. Material and methods: This nationwide case-control study was based on the Swedish Colorectal Cancer Registry with supplementary information from medical records and the Swedish Inpatient Registry during the period 2000–2008. All resected rectal cancer patients with synchronous metastases that survived more than five years were included as cases. The control group consisted of corresponding patients who lived less than five years, matched in a 1:2 based on gender, age, resection of the rectal tumor, and the study period. Results: A total of 405 patients were identified; 99 long-term survivors (LTS) and 182 short-term survivors (STS). Patient-related factors of symptoms and comorbidity did not differ between LTS and STS. Among the treatment-related factors, multiple site metastases (p = 0.007), bilobar liver metastasis (p = 0.002), and increasing number of liver metastasis (p < 0.001) were associated with STS. Prognostic treatment-related factors were preoperative radiotherapy (p = 0.001), metastasectomy (p < 0.001), and radical resection of the primary tumor (p = 0.014). In the multivariable analysis, the single most important factor for becoming a LTS was a metastasectomy (hazard ratio: 8.474, 95% confidence interval: 4.098–17.543). Conclusions: The most important prognostic factor for long-term survival in patients with stage IV rectal cancer was metastasectomy, especially liver surgery. With thorough selection of patients for metastasectomy more patients with metastasized rectal cancer may survive beyond five years. © 2019 Elsevier Ltd

Risk factors for small bowel obstruction after open rectal cancer resection
- 2021
-
Ingår i: BMC Surgery. - : BioMed Central (BMC). - 1471-2482. ; 21:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Small bowel obstruction (SBO) is observed in around 10% of patients with prior open abdominal surgery. Rectal resection causes the highest readmission rates. The aim of this study was to investigate risk factors for readmission for SBO and causes for SBO in patients who needed surgery following rectal cancer surgery.Methods: A population-based registry with prospectively gathered data on 752 consecutive patients with rectal cancer who underwent open pelvic surgery between January 1996 and January 2017 was used. Univariable and multivariable regression analysis was performed, and the risk of SBO was assessed.Results: In total, 84 patients (11%) developed SBO after a median follow-up time of 48 months. Of these patients, 57% developed SBO during the 1st year after rectal cancer surgery. Surgery for SBO was performed in 32 patients (4.3%), and the cause of SBO was stoma-related in one-fourth of these patients. In the univariable analysis previous RT and re-laparotomy were found as risk factors for readmission for SBO. Re-laparotomy was an independent risk factor for readmission for SBO (OR 2.824, CI 1.129-7.065, P = 0.026) in the multivariable analysis, but not for surgery for SBO. Rectal resection without anastomoses, splenic flexors mobilization, intraoperative bleeding, operative time were not found as risk factors for SBO.Conclusions: One-tenth of rectal cancer patients who had open surgery developed SBO, most commonly within the 1st postoperative year. The risk of SBO is greatest in patients with complications after rectal cancer resection that result in a re-laparotomy.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Survival among patients with stage IV rectal cancer is poor and surgical treatment for this disease is associated with morbidities such as small bowel obstruction, complications with a diverting loop ileostomy, and functional bowel disturbances. The overall aim of this thesis was to assess risk factors and morbidity after surgery for rectal cancer and to evaluate factors affecting survival in patients with stage IV rectal cancer.Paper I a prospective study on patients with rectal cancer with loop ileostomy who underwent stoma closure in a 23-hour hospital stay setting. Results were compared with a group who underwent standard in-hospital stoma closure prior to the start of the study, selected retrospectively as controls. No differences were found in the number of complications or the frequency of re-hospitalization or re-operation, indicating that ileostomy closure in a 23-hour hospital stay setting in these selected patients was feasible and safe with high patient satisfaction.Paper II a population-based study with data gathered prospectively. In total, 11% of the patients developed small bowel obstruction (SBO), mostly during the first year after rectal cancer surgery. Surgical treatment for SBO was performed in 4.2% of the patients, and the mechanism was stoma-related in one-fourth. Rectal resection without anastomoses, age, morbidity, and previous radiotherapy (RT) was not associated with admission to the hospital or surgery for SBO. Re-laparotomy due to complications after rectal cancer surgery was an independent risk factor for admission for treating SBO.Paper III a population-based study with data gathered prospectively on bowel function at 1 year after anterior resection or stoma reversal. No associations were found between any defecatory dysfunction and the part of the colon used for anastomosis, the level of the vascular tie, or gender. An association was observed between higher anastomotic level and a lower risk of incontinence and clustering. At 1 year after loop ileostomy closure, the risks of incontinence, clustering, and urgency increased by up to fourfold.Paper IV a case-control study aiming to identify patient-, tumor-, and treatment-related prognostic factors for 5-year survival in patients with rectal cancer with synchronous stage IV disease. Patient-related factors did not differ between groups. Among the tumor-related factors, multiple site metastases, bilobar liver metastases, and increasing numbers of liver metastases were associated with poor survival. Prognostic treatment-related factors were preoperative RT, metastasectomy, and radical resection of the primary tumor. The most important prognostic factor for long-term survival was metastasectomy.

Forskningsöversikt (refereegranskat)abstract
- Left-sided colonic diverticulitis is a common condition with significant morbidity and health care costs in Western countries. Acute uncomplicated diverticulitis which is characterized by the absence of organ dysfunction, abscesses, fistula, or perforations accounts for around 80% of the cases. In the last decades, several traditional paradigms in the management of acute uncomplicated diverticulitis have been replaced by evidence-based routines. This review provides a comprehensive evidence-based and clinical-oriented overview of up-to-date diagnostics with computer tomography, non-antibiotic treatment, outpatient treatment, and surgical strategies as well as follow-up of patients with acute uncomplicated diverticulitis.

Colonic Diverticulitis : Diagnostic and Therapeutic Aspects
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aims of this thesis were to evaluate diagnostic and therapeutic aspects of colonic diverticulitis. In the first study, a systematic review of the literature was performed to evaluate radiological diagnostics for patients with acute left-sided diverticulitis. Forty-nine relevant articles were found and read in full and data were extracted or calculated. Twenty-nine of these were excluded. The best evidence for the diagnosis of diverticulitis in the literature was to be found with US. Only one small study of good quality was found for both CT and MRI. In the second paper, a prospective multicentre study was performed to determine the faecal carriage of antibiotic-resistant bacteria and antibiotic treatment in 208 surgical patients with acute intra-abdominal infections. The highest rates of resistance among Enterobacteriaceae were detected for ampicillin (54%), tetracycline (26%), cefuroxime (26%) and trimethoprim-sulfamethoxazole (20%). The prevalence of decreased susceptibility (I + R) for the other antibiotics tested was for ciprofloxacin 20%, piperacillin-tazobactam 17%, cefotaxime 14%, ertapenem 12%, gentamicin 3% and imipenem 0%. ESBL- and AmpC producing Enterobacteriaceae were found in samples from 13 patients (6.3%). We found high rates of resistance among Enterobacteriaceae against antibiotics which were commonly used in Sweden. In the third paper, a multicentre randomized study was performed to investigate the need of antibiotic treatment in acute uncomplicated diverticulitis. Six hundred and twenty-three patients were randomized to treatment with (314 patients) or without (309 patients) antibiotics. Complications were found in six patients (1.9%) in the no antibiotic and three (1.0%) in the antibiotic group (p=0.302). The median hospital stay was three days in both groups. Recurrent diverticulitis follow-up was similar in both groups (16%, p=0.895). We conclude that antibiotic treatment for acute uncomplicated diverticulitis neither accelerated recovery nor prevented complications or recurrence. Based on the results, antibiotics should therefore be reserved mainly for the treatment of complicated diverticulitis. The fourth paper presents a prospective observational study performed in two centres to evaluate CT colonography in the follow-up of acute diverticulitis as regards patient acceptance and diagnostic accuracy in 108 patients. Patients experienced colonoscopy as more painful (p<0.001) and uncomfortable (p<0.001). Diverticulosis and polyps were detected in 94% and 20% with colonoscopy and in 94% and 29% with CTC, respectively. Sensitivity and specificity for CTC in the detection of diverticulosis was 99% and 67%, with a level of relatively good agreement (К= 0.71). Regarding detection of polyps, the sensitivity and specificity were 47% and 75%, with a poor agreement (К= 0.17). We concluded that CTC was less painful and unpleasant. CTC detected diverticulosis with good accuracy while the accuracy of detection of small polyps was poor. CTC could be an alternative, especially in cases of incomplete colonoscopy or in a situation with limited colonoscopy resources.

- Objective. The aim of this study was to assess CT-colonography (CTC) in the follow-up of diverticulitis regarding patient acceptance and diagnostic accuracy for diverticular disease, adenomas and cancer, with colonoscopy as a reference standard. Methods. A prospective comparative study where half of the patients underwent colonoscopy first, followed immediately by CTC. The other half had the examinations in the reverse order. Patient experiences and findings were registered after every examination, blinded to the examiner. Results. Of a total of 110 consecutive patients, 108 were included in the study, with a median age of 56 years (range 27-84). The success rate was 91% for colonoscopy and 86% for CTC. Examination time was 25 mm for both methods. The mean time for CTC evaluation was 20 mm. Eighty-three per cent of the patients received sedation during colonoscopy. Despite this, patients experienced colonoscopy as more painful (p < 0.001) and uncomfortable (p < 0.001). Diverticulosis and polyps were detected in 94% and 20% with colonoscopy and in 94% and 29% with CTC, respectively. Sensitivity and specificity for CTC in the detection of diverticulosis was 99% and 67%, with a good agreement (kappa = 0.71). Regarding detection of polyps, the sensitivity and specificity were 47% and 75%, with a poor agreement (kappa = 0.17). No cancer was found. Conclusion. CTC was less painful and unpleasant and can be used for colonic investigation in the follow-up of diverticulitis. CTC detected diverticulosis with good accuracy while the detection accuracy of small polyps was poor. CTC is a viable alternative, especially in case of incomplete colonoscopy or in a situation with limited colonoscopy resources.

- First-time acute uncomplicated diverticulitis (AUD) has been considered to have an increased risk of complication, but the level of evidence is low. The aim of the present study was to evaluate the risk of complications in patients with first-time AUD and in patients with a history of diverticulitis. This paper is a population-based retrospective study at Vastmanland's Hospital, VasterAs, Sweden, where all patients were identified with a diagnosis of colonic diverticular disease ICD-10 K57.0-9 from January 2010 to December 2014. The records of all patients were surveyed and patients with a computed tomography (CT)-verified AUD were included. Complications defined as CT-verified abscess, perforation, colonic obstruction, fistula, or sepsis within 1 month from the diagnosis of AUD were registered. Of 809 patients with AUD, 642 (79%) had first-time AUD and 167 (21%) had a previous history of AUD with no differences in demographic or clinical characteristics. In total, 16 (2%) patients developed a complication within 1 month irrespective of whether they had a previous history of diverticulitis (P = 0.345). In the binary logistic regression analysis, first-time diverticulitis was not associated with increased risk of complications (OR 1.58; CI 0.52-4.81). The rate of antibiotic therapy was about 7-10% during the time period and outpatient management increased from 7% in 2010 to 61% in 2014. The risk for development of complications is low in AUD with no difference between patients with first-time or recurrent diverticulitis. This result strengthens existing evidence on the benign disease course of AUD.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study aimed to evaluate the association of socioeconomic status and comorbidities with uncomplicated and complicated diverticular disease (DD) in Sweden.Methods: We identified all individuals aged >= 30 years in Sweden diagnosed with DD between 1997 and 2012 using the Swedish National Population and Housing Census and the Hospital Discharge Register. Data were analyzed by multivariable logistic regression, with individual-level characteristics as covariates.Results: A total of 79,481 patients (median age 66 [range 3086] years) were hospitalized for DD, 15,878 (20%) of whom for complicated DD. Admissions for both uncomplicated and complicated DD were more common in women (p < 0.001). A low education level was identified as a risk factor for uncomplicated (unadjusted hazard ratio [HR] 1.79, 95% confidence interval [CI] 1.75-1.82; adjusted HR 1.22, 95% CI 1.19-1.24) and complicated DD(unadjusted HR 1.84, 95% CI 1.77-1.92; adjusted HR 1.26, 95% CI 1.21-1.32). Patients with the lowest income had a lower risk of hospitalization for uncomplicated (adjusted HR 0.94, 95% CI 0.91-0.96) and complicated DD (adjusted HR 0.87, 95% CI 0.83-0.92) than those with the highest income. The correlation coefficient between income and education was 0.25. Diabetes and cardiovascular disease were identified as protective factors against uncomplicated DD (adjusted HR 0.68, 95% CI 0.66-0.69 and HR 0.79, 95% CI 0.74-0.84, respectively).Conclusions: Patients with the lowest education level had an increased risk of hospitalization for DD. Further studies are needed to explore the association of diabetes and cardiovascular disease with uncomplicated DD.

- Background: The aim of this study was to assess the long-term results in patients with uncomplicated diverticulitis who had participated in the Antibiotics in Acute Uncomplicated Diverticulitis (AVOD) RCT, which randomized patients with CT-verified left-sided acute uncomplicated diverticulitis to management without or with antibiotics.Methods: The medical records of patients who had participated in the AVOD trial were reviewed for long-term results such as recurrences, complications and surgery. Quality-of-life questionnaires (EQ-5D (TM)) were sent to patients, who were also contacted by telephone. Descriptive statistics were used for the analysis of clinical outcomes.Results: A total of 556 of the 623 patients (89 center dot 2 per cent) were followed up for a median of 11 years. There were no differences between the no-antibiotic and antibiotic group in recurrences (both 31 center dot 3 per cent; P = 0 center dot 986), complications (4 center dot 4 versus 5 center dot 0 per cent; P = 0 center dot 737), surgery for diverticulitis (6 center dot 2 versus 7 center dot 1 per cent; P = 0 center dot 719) or colorectal cancer (0 center dot 4 versus 2 center dot 1 per cent; P = 0 center dot 061). The response rate for the EQ-5D (TM) was 52 center dot 8 versus 45 center dot 2 per cent respectively (P = 0 center dot 030), and no differences were found between the two groups in any of the measured dimensions.Conclusion: Antibiotic avoidance for uncomplicated diverticulitis is safe in the long term.

- Purpose:Outpatient management without antibiotics has been shown to be safe for selected patients diagnosed with acute uncomplicated diverticulitis (AUD). The aim of this study was to evaluate the impact on admissions, complication rates and health-care costs of the policy of outpatient treatment without using antibiotics.Methods:The medical records of all patients diagnosed with AUD in the year before (2011) and after (2014) the implementation of outpatient management without antibiotics in Vastmanland County were reviewed. Health-care cost analysis was performed using the Swedish cost-per-patient model.Results:In total, 494 episodes of AUD were identified, 254 in 2011 and 240 in 2014. The proportion of patients managed as outpatients was 20% in 2011 compared with 60% in 2014 (p<.001). There were 203 hospital admissions and a total length of stay of 677 days in 2011 compared with 95 admissions and 344 days in 2014 (both p<.001). The total health-care cost was Euro558,679 in 2011 compared with Euro370,370 in 2014 (p<.001). Three patients developed complications in 2011 and four in 2014 (p=.469).Conclusions:The new policy of outpatient management without antibiotics in routine health care almost halved the total health-care cost without an increase in the complication rate.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis was to evaluate the clinical management of AUD with regard to the no-antibiotic policy and its long-term effect, treatment on an outpatient basis and the potential health-care cost savingsStudy I: a retrospective study at Västmanlands Hospital that evaluated and confirmed the adherence to the no-antibiotic policy in patients with AUD and its safety regarding complications and recurrences. A total of 246 patients with acute diverticulitis were identified, of which 195 had computed tomography (CT) confirmed AUD. In total, 91.3% of these patients did not receive any antibiotics and only two developed complications.Study II: a retrospective study with the aim to conduct a long-term follow-up of all Swedish patients who participated in the AVOD trial in terms of recurrences, complications, surgery and quality of life. The medical records of 96% of the patients were reviewed with a mean follow up of 11 years. Quality of life questionnaires were sent out to all patients. There were no differences regarding the rates of recurrence, complications or surgery for diverticulitis. There were no differences in the quality of life between groups according to the EQ-5D questionnaire.Study III: a prospective study where 155 patients with CT-verified AUD as were treated as outpatients without antibiotics. On day 3, patients reported an average pain score of 1.8 of 10 on the VAS scale and only 30% of patients were using analgesia. Four patients returned to hospital because of treatment failure.Study IV: a retrospective cohort study at Västmanland’s Hospital evaluated the impact on admissions, complication rates and health-care costs of the policy of outpatient treatment without using antibiotics. Medical records of all patients diagnosed with AUD in the year before (2011) and after (2014) the implementation of outpatient management without antibiotics were reviewed. Overall 494 episodes of AUD were identified: 254 in 2011 and 240 in 2014. Three patients developed complications in 2011 and four in 2014. The proportion of patients managed as outpatients was 20% in 2011 compared with 61% in 2014. The hospital admissions, total length of stay of and total health-care costs were almost halved.In conclusion, these studies confirm the low complication and recurrence rates of AUD and strengthens findings that antibiotics have no benefit in the treatment of this disease. The no-antibiotic policy had no impact on short- or long-term outcomes regarding the rates of recurrence, complications, surgery or quality of life. Outpatient management was found to be feasible and safe, and significantly reduced admissions, which led to large health-care cost savings.

- Background/Aim: The aim of the present study was to describe a double immunocytochemical staining method for detecting free cancer cells after rectal cancer surgery and to evaluate their extent and prognostic role. Materials and Methods: Immunocytochemistry was performed using antibodies against cytokeratin 20/caudal-typehomeobox transcription factor 2 (CDX2) and mucin glycoprotein-2 (MUC2)/p53 protein. The study included 29 patients with infraperitoneal rectal cancer who underwent bowel resection and four controls. The pelvic lavage was retrieved at the start of laparotomy, after total mesorectal excision and after abdominal lavage with sterile water. Results: Free cancer cells were detected with the double immunocytochemical method in the two controls with carcinomatosis and one control with sigmoidal cancer. None of the patients with rectal tumours had presence of free cancer cells. Conclusion: Immunocytochemical analysis of peritoneal lavage was feasible and negative in patients with infraperitoneal rectal cancer. Further studies are encouraged to investigate the clinical relevance in cases with free cancer cells after incomplete total mesorectal excision.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: The metabolic syndrome (MetS) represents a cluster of risk factors that predict cardiovascular disease (CVD) and type 2 diabetes. Early detection of MetS opens up for a successful treatment of the cardiovascular (CV) risk factors involved, hopefully leading to later advent of CVD in the general population.Purpose: In this long-term, population-based study we aimed to investigate how presence of MetS, in middle-aged men and women, was associated with all-cause mortality and non-fatal CVD later in life.Methods: Between 1990 -1999 a screening program was conducted among 40- and 50-year-old inhabitants in the County of Västmanland, Sweden. Data on lifestyle habits and socio-economic status were collected. Total cholesterol, fasting blood glucose, blood pressure, weight, height, waist and hip circumference were measured. Individuals that met three or more of the following risk factors were classified with MetS: waist circumference: ≥102 cm (men) and ≥88 cm (women), total cholesterol: ≥6.1 mmol/ l, blood pressure: ≥130 and/ or ≥85 mm Hg (or previous diagnosis of hypertension) or fasting plasma glucose: ≥5.6 mmol/ l (or previous diagnosis of type 2 diabetes). A control group was identified with individuals from the same population, without MetS diagnosis. Each participant with MetS was matched to two controls regarding sex, age and date for the health examination. The association between midlife MetS and all-cause mortality and non-fatal CV events (stroke and myocardial infarction) was adjusted for age, sex, smoking, physical inactivity, educational level, BMI, hip circumference and living alone or with family members. Multivariable cox regression and Kaplan-Meier analyses were used.Results: A total number of 5084 individuals met the criteria for MetS and a control group of 10 168 individuals was identified. The median (Q1, Q3) follow-up time was 27 years (24.6, 30.1), corresponding to 130 820 and 269 696 person-years at risk in the MetS and the control group respectively. During follow up, 1317 MetS and 1904 control subjects died, implying 10 deaths in the MetS group and 7 deaths in the controls per 1000 person-years at risk (fig. 1). Cox analysis showed increased mortality in the MetS group compared to the controls, hazard ratio (HR) 1.30 (95% CI: 1.20-1.40); p<0.001. Non-fatal CV events in the MetS group and in the controls were 32.4% vs 22.8%, respectively (p<0.001); HR 1.35 (CI;1.25–1.46) (fig 2). Median time (Q1, Q3) for first non-fatal CV event was 16.8 years (9.9,22.3) in the MetS group and 19.1 (12.2, 23.6) for the controls.Conclusions: Results from this long-term, population-based study underline that the risk of non-fatal CVD and all-cause mortality was significantly higher in individuals with asymptomatic MetS. Present results support previous studies that early identification of MetS with screening programs might open a window of opportunity for prevention of CVD and premature death in the general population.

- Background: There is substantial evidence that midlife hypertension is a risk factor for late life dementia. Our aim was to investigate if even high blood pressure at a single timepoint in midlife can predict an increased risk for all-cause dementia, Alzheimer's disease (AD), or vascular dementia (VaD) later in life. Methods: The community-based study population comprised 30,102 dementia-free individuals from the Westmannia Cardiovascular Risk Factors Study. The participants were aged 40 or 50 years when the health examination took place in 1990-2000. Diagnose registers from both hospitals and primary healthcare centers were used to identify individuals who after inclusion to the study developed dementia.The association between midlife high blood pressure (defined as systolic blood pressure >140 and/or diastolic blood pressure >90 mmHg) at a single timepoint and dementia was adjusted for age, gender, body mass index (BMI), fasting blood glucose, education, smoking, and physical activity level. Multivariate binary cox regression analyses were used. Results: After a mean follow-up time of 24 years resulting in 662,244 person/years, 761 (2.5%) individuals had been diagnosed with dementia. Midlife high blood pressure at a single timepoint predicted allcause dementia (hazard ratio [HR]: 1.22, 95% confidence interval [CI]: 1.02-1.45) and VaD (HR: 2.10, 95% CI: 1.47-3.00) but not AD (HR: 1.06, 95% CI: 0.81-1.38). Conclusion: This study suggests that even midlife high blood pressure at a single timepoint predicts allcause dementia and more than doubles the risk for VaD later in life independently of established confounders. Even though there was no such association with AD, this strengthens the importance of midlife health examinations in order to identify individuals with hypertension and initiate treatment.

Tidskriftsartikel (refereegranskat)abstract
- Background: An open observational study was performed to investigate changes in the rectal flora and antibiotic susceptibility among faecal bacteria in patients treated with antibiotics for acute intra-abdominal infection. Methods: One hundred and forty patients with acute intra-abdominal infection requiring antibiotic treatment and hospitalization were included. Eight surgical units from the southern part of Sweden participated, between January 2006 and November 2007. Antibiotic treatments were according to local guidelines. Rectal swabs were obtained on admission (sample 1) and 214 days after the end of antibiotic treatment (sample 2). Aerobic bacteria and yeasts were analysed. The material was divided into 2 groups: 1 group with Enterobacteriaceae and 1 group with non-fermentative Gram-negative bacteria. The susceptibility to antibiotics in each group was compared between samples 1 and 2. Results: The main finding of this study on patients with severe intra-abdominal infections was a shift in the aerobic faecal flora following antibiotic treatment, from Escherichia coli to other more resistant Enterobacteriaceae, Enterococcus faecium, and yeasts. The susceptibility to cephalosporins and piperacillintazobactam decreased in Enterobacteriaceae. Conclusions: Following antibiotic treatment, a shift in the aerobic rectal flora to species with intrinsic antibiotic resistance was observed. This indicates that the emergence of resistance is not due to new mutations, but rather to selection of more resistant species. This should be taken into account when designing treatments for secondary intra-abdominal infections.

Disturbed intestinal microbiota (dysbiosis) and micro dynamics in patients treated for appendicitis and diverticulitis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: The human gut microbiota is a large dynamic bacterial community, which is influenced by for instance antibiotic treatment and hospitalization. In patients with inflammatory bowel disease the diversity of gut microbiota is thought to be less diverse. The role of the gut microbiota in acute appendicitis and diverticulitis is still unclear. To investigate the microbial diversity in patients suffering from appendicitis or diverticulitis, and the microbiota dynamics after antibiotic therapy and hospitalization we performed an open observation study.Methods and population: We have performed 16S rRNA sequence analysis on 42 individuals diagnosed with appendicitis and 18 individuals with diverticulitis as well as 33 healthy controls. Cultivation of the aerobic bacterial flora was performed as a complement to sequence analysis.Results: In sequencing data at genus level, there are distinctive differences when comparing healthy controls to patients diagnosed with appendicitis. Healthy controls have a flora dominated by Bacteroides, and Faecalibacterium, Ruminococcus and Prevotella while appendicitis patients show an intestinal flora with a higher abundance of Escherichia/Shigella and unclassified Enterobacteriaceae. The same pattern, however not quite as distinct could be seen for the diverticulitis patients. The microbial diversity increases after treatment with antibiotics and hospitalization.In the cultivated aerobic flora there was a significant loss of Escherichia coli and a significant gain of Citrobacter species, in the appendicitis group. In the appendicitis group as well as in the diverticulitis group there was a significant gain of Enterococcus faecium and Yeasts.Conclusion: The main findings of this study are that patients arriving at the emergency department with acute appendicitis or diverticulitis have an already significant disturbed fecal microbiota previous to antibiotic treatment and hospitalization.

Tidskriftsartikel (refereegranskat)abstract
- Aim The goal of this European Society of Coloproctology (ESCP) guideline project is to give an overview of the existing evidence on the management of diverticular disease, primarily as a guidance to surgeons. Methods The guideline was developed during several working phases including three voting rounds and one consensus meeting. The two project leads (JKS and EA) appointed by the ESCP guideline committee together with one member of the guideline committee (WB) agreed on the methodology, decided on six themes for working groups (WGs) and drafted a list of research questions. Senior WG members, mostly colorectal surgeons within the ESCP, were invited based on publication records and geographical aspects. Other specialties were included in the WGs where relevant. In addition, one trainee or PhD fellow was invited in each WG. All six WGs revised the research questions if necessary, did a literature search, created evidence tables where feasible, and drafted supporting text to each research question and statement. The text and statement proposals from each WG were arranged as one document by the first and last authors before online voting by all authors in two rounds. For the second voting ESCP national representatives were also invited. More than 90% agreement was considered a consensus. The final phrasing of the statements with < 90% agreement was discussed in a consensus meeting at the ESCP annual meeting in Vienna in September 2019. Thereafter, the first and the last author drafted the final text of the guideline and circulated it for final approval and for a third and final online voting of rephrased statements. Results This guideline contains 38 evidence based consensus statements on the management of diverticular disease. Conclusion This international, multidisciplinary guideline provides an up to date summary of the current knowledge of the management of diverticular disease as a guidance for clinicians and patients.

- Purpose: The purpose of this study was to evaluate the disease pattern and treatment of diverticular abscesses. Methods: Patients treated for diverticulitis (K57) in Vastmanland, Sweden were identified for this retrospective population-based study between January 2010 and December 2014. Patients with diverticular abscesses were included. The clinical and radiological data were extracted, and the computed tomography scans were reevaluated. Results: Of the 75 patients (45 women) with a median age of 62 years (range: 23-88 years), abscesses were localized pericolic in 42 patients (59%) and in the pelvis in 33 patients (41%). The median abscess size was 4.8 cm (range: 1.1-11.0 cm). Six patients (8%) required urgent surgical intervention during the index admission. The median follow-up time was 58 months (range: 0-95 months). During follow-up, 40 patients (58%) had disease recurrence and 35 of these patients (88%) presented with complicated diverticulitis. The median time until re-admission was 2 months (range: 3 days-94 months). Patients with pelvic abscesses developed fistulas more frequently, 3 versus 11 patients (p = .003). Twenty-three percent of patients with pericolic abscesses required surgery compared with 40% of patients with pelvic abscesses (p = .09). No patients had a recurrence of abscesses after a colonic resection. Conclusion: The majority of patients with diverticular abscesses had recurrences with repeated admissions regardless of abscess location. An unexpectedly high proportion of patients required surgical intervention during the follow-up period. A liberal approach regarding elective surgery for patients with recurrent diverticulitis abscesses who tolerate surgery seems justified.

- Background: The aim of this study was to identify clinical factors leading to increased diagnostic accuracy for acute colonic diverticulitis. Methods: Patients with clinical suspicion of acute colonic diverticulitis verified with computed tomography (CT) from two hospitals in Sweden between 9 January 2017 and 31 October 2017 were prospectively included. Symptoms, comorbidities, and laboratory results were documented. Candidate variables were analyzed using logistic regression, and the final variable set that yielded the most accurate predictions was identified using least absolute shrinkage and selection operator regression and evaluated using the area under the receiver operating characteristic (ROC) curve. Results: In total, 146 patients were included (73% women; median age 68 years; age range, 50-94 years). The clinical diagnostic accuracy was 70.5%. In the multiple logistic regression analysis, gender (female vs male odds ratio [OR]: 4.82; confidence interval [CI], 1.56-14.91), age (OR, 0.92; 95% CI, 0.87-0.98), pain on the lower left side of the abdomen (OR, 15.14; 95% CI, 2.65-86.58), and absence of vomiting (OR, 14.02; 95% CI, 2.90-67.88) were statistically significant and associated with the diagnosis of CT-verified diverticulitis. With seven predictors (age, gender, urinary symptoms, nausea, temperature, C-reactive protein, and pain left lower side), the area under the ROC curve was 0.82, and a formula was developed for calculating a risk score. Conclusion: We present a scoring system using common clinical variables that can be applied to patients with clinical suspicion of colonic diverticulitis to increase the diagnostic accuracy. The developed scoring system is available for free of charge at https://phille-wagner.shinyapps.io/Diverticulitis_risk_model/.

- Introduction:There are little data on the post-operative outcome of anterior resection (AR) for rectal cancer in men who had received radiotherapy for prostate cancer previously. The aim of this study was to assess the rate of anastomotic leakage (AL) after AR in these patients.Methods:All men who underwent bowel resection because of rectal cancer between 2000 and 2016 and had been diagnosed previously with prostate cancer were identified by linking the Swedish Colorectal Cancer Registry with the National Prostate Cancer Register. The medical records of men who underwent AR and had previously received radiotherapy for prostate cancer were reviewed.Results:In total, 13299 men had undergone a bowel resection for rectal cancer, 188 of whom had previously received radiotherapy for prostate cancer. Among those who had received radiation therapy, 59 men (31%) had an AR: 50 men (85%) received a diverting ileostomy, 42 men (71%) had an American Society of Anesthesiologists score of 1-2 and 36 men (61%) had tumour stage 1-2. AL was found in 12/59 men (20%), one of whom had a re-laparotomy. There was no 90-day mortality.Conclusions:In the combined national population-based registries, a minority of patients with rectal cancer had an AR after previous radiotherapy for prostate cancer. These patients were healthy with early cancer stages and, in this selected group of patients, the AL rate was much lower than that reported previously.

- To describe the postoperative surgical complications in patients with rectal cancer undergoing Hartmann's procedure (HP). Data were retrieved from the Swedish Colorectal Cancer Registry for all patients with rectal cancer undergoing HP in 2007-2014. A retrospective analysis was performed using prospectively recorded data. Characteristics of patients and risk factors for intra-abdominal infection and re-laparotomy were analysed. Of 10,940 patients resected for rectal cancer, 1452 (13%) underwent HP (median age, 77 years). The American Society of Anesthesiologists (ASA) score was 3-4 in 43% of patients; 15% had distant metastases and 62% underwent a low HP. The intra-abdominal infection rate was 8% and re-laparotomy rate was 10%. Multivariable logistic regression analysis identified preoperative radiotherapy (OR, 1.78; 95% CI, 1.14-2.77), intra-operative bowel perforation (OR, 1.99; 95% CI, 1.08-3.67), T4 tumours (OR, 1.68; 95% CI 1.04-2.69) and female gender (OR, 1.73; 95% CI, 1.15-2.61) as risk factors for intra-abdominal infection. ASA score 3-4 (OR, 1.62; 95% CI, 1.12-2.34), elevated BMI (OR, 1.05; 95% CI, 1.02-1.09) and female gender (OR, 2.06; CI, 1.41-3.00) were risk factors for re-laparotomy after HP. The rate of intra-abdominal infection was not increased after a low HP. Despite older age and co-morbidities including more advanced cancer, patients undergoing Hartmann's procedure had low rates of serious postoperative complications and re-laparotomy. A low HP was not associated with a higher rate of intra-abdominal infection. HP seems to be appropriate for old and frail patients with rectal cancer.

Rectal cancer : Aspects of post-operative complications
- 2018
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Aim: The overall aim of this thesis was to study post-operative complications in patients with rectal cancer.Methods: Post-operative complications in patients operated for rectal cancer was retrospectively analyzed in three prospective registers; the local rectal cancer registry in the Västmanland County, Sweden, the Swedish Colorectal Cancer Registry (SCRCR) and the National Prostate Cancer Registry (NPCR). In Papers I and II, the focus was on the complication pattern after Hartmann’s procedure (HP). In Paper III, the incidence of parastomal hernia was assessed during a period when no prophylactic mesh was used (1996-2006) compared with a period when a prophylactic mesh was routinely used (2007-2012). In Paper IV, the anastomotic leakage (AL) rate after anterior resection (AR) for rectal cancer patients who had previously received RT for prostate cancer was assessed with combined data from the SCRCR and the NPCR.Results: In Paper I, patients operated with a HP were significantly older, had a higher ASA-score, a poorer WHO performance score and lower serum albumin levels. Few developed pelvic complications. In Paper II, the intra-abdominal infection rate was 8% and the re-laparotomy rate was 10%. Multi-variable logistic regression analysis identified pre-operative radiotherapy as a risk factor for intra-abdominal infections. In Paper III, we found no difference in the rate of parastomal hernia between patients with and without a prophylactic stoma mesh. In Paper IV, we identified 59 out of 188 patients who had undergone previous radiation therapy for prostate cancer who had been operated with AR. Twelve (20%) developed an AL, of whom only one underwent re-laparotomy and there was no 90-day mortality.Conclusion: The rate of serious post-operative complications was low after HP and it seems to be a safe and appropriate alternative in old and frail patients. Pre-operative radiotherapy was a risk factor for intra-abdominal infections in rectal cancer patients operated with a HP. A prophylactic stoma mesh did not reduce the rate of parastomal hernias. In patients that had previously been irradiated for prostate cancer, a minority underwent an AR. These patients were healthy with early cancer stages and, in this selected group of patients, the AL rate was much lower than previously reported.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To evaluate the diagnostic accuracy of non-enhanced low-dose computed tomography (LDCT) in acute colonic diverticulitis with contrast-enhanced standard-dose CT (SDCT) as the reference method.Materials and Methods: Consecutive patients with clinically suspected diverticulitis were included from two hospitals between January and October 2017. All patients underwent LDCT followed by SDCT. All CT examinations were assessed for signs of diverticulitis, complications, and other diagnoses by three independent radiologists (two radiology consultants and one fourth-year resident) using SDCT as the reference method. Sensitivity, specificity, and agreement were calculated.Results: In total, 149 patients (median age 68, 107 women) were included; 107 had diverticulitis on standard CT. Sensitivity for diverticulitis using LDCT was 100%; the values were 99% for consulting radiologists and 92% for the radiology resident. Specificity was 100% for both consultants and 84% for the resident. Sensitivity for identification of complications was 74%, 60%, and 54%, respectively. Twenty-six patients had other causes of abdominal symptoms on standard CT, 23 (88%) of whom were diagnosed correctly on LDCT. One case of splenic infarction and two cases of segment colitis were missed on LDCT.Conclusion: The diagnostic accuracy of LDCT was high for acute diverticulitis. Therefore, it is recommended as a standard method that should help to reduce radiation dose and cost. LDCT had lower sensitivity for complications, although discrimination between an inflamed diverticulum and small pericolic abscess accounted for a proportion of the discrepancies.

- Objectives: The aim of this study was to describe patient characteristics and results of non-operative management for patients presenting with computed tomography (CT) verified perforated diverticulitis with extraluminal or free air.Methods: All patients treated for diverticulitis (ICD-10: K-57) during 2010–2014 were identified and medical records were reviewed. Re-evaluations of CT examinations for all patients with complicated disease according to medical records were performed. All patients diagnosed with perforated diverticulitis and extraluminal or free air on re-evaluation were included and characteristics of patients having immediate surgery and those whom non-operative management was attempted are described.Results: Of 141 patients with perforated diverticulitis according to medical records, 136 were confirmed on CT re-evaluation. Emergency surgical intervention within 24 h of admission was performed in 29 (21%) patients. Non-operative management with iv antibiotics was attempted for 107 patients and was successful in 101 (94%). The 30-day mortality rate was 2%. The presence of a simultaneous abscess was higher for patients with failure of non-operative management compared with those that were successfully managed non-operatively (67% compared to 17%, p = .013). Eleven out of thirty-two patients (34%) with free air were successfully managed conservatively. Patients that were operated within 24 h from admission were more commonly on immunosuppressive therapy, had more commonly free intraperitoneal air and free fluid in the peritoneal cavity.Conclusions: Non-operative management is successful in the majority of patients with CT-verified perforated diverticulitis with extraluminal air, and also in one-third of those with free air in the peritoneal cavity.

Tidskriftsartikel (refereegranskat)abstract
- Aim To compare the number of appendicitis cases and its complications, during the first months of the COVID-19 pandemic in Sweden and the UK and the corresponding time period in 2019. Method Reports of emergency abdominopelvic CT performed at 56 Swedish hospitals and 38 British hospitals between April and July 2020 and a corresponding control cohort from 2019 were reviewed. Two radiologists and two surgeons blinded to the date of cohorts analyzed all reports for diagnosis of appendicitis, perforation, and abscess. A random selection of cases was chosen for the measurement of inter-rater agreement. Result Both in Sweden (6111) and the UK (5591) fewer, abdominopelvic CT scans were done in 2020 compared to 2019 (6433 and 7223, respectively); p < 0.001. In the UK, the number of appendicitis was 36% lower in April-June 2020 compared to 2019 but not in Sweden. Among the appendicitis cases, there was a higher number of perforations and abscesses in 2020, in Sweden. In the UK, the number of perforations and abscesses were initially lower (April-June 2020) but increased in July 2020. There was a substantial inter-rater agreement for the diagnosis of perforations and abscess formations (K = 0.64 and 0.77). Conclusion In Sweden, the number of appendicitis was not different between 2019 and 2020; however, there was an increase of complications. In the UK, there was a significant decrease of cases in 2020. The prevalence of complications was lower initially but increased in July. These findings suggest variability in delay in diagnosis of appendicitis depending on the country and time frame studied.

Tidskriftsartikel (refereegranskat)abstract
- Background Two RCTs (AVOD and DIABOLO) demonstrated no difference in recovery or adverse outcomes when antibiotics for acute uncomplicated diverticulitis were omitted. Both trials showed non-significantly higher rates of complicated diverticulitis and surgery in the non-antibiotic groups. This meta-analysis of individual-patient data aimed to explore adverse outcomes and identify patients at risk who may benefit from antibiotic treatment.Methods Individual-patient data from those with uncomplicated diverticulitis from two RCTs were pooled. Risk factors for adverse outcomes and the effect of observational management were assessed using logistic regression analyses. P < 0·025 was considered statistically significant owing to multiple testing adjustment.Results In total, 545 patients in the observational group and 564 in the antibiotics group were included. No statistical differences were found in 1-year follow-up rates of ongoing diverticulitis (7·2 versus 5·0 per cent in observation versus antibiotics groups respectively; P = 0·062), recurrent diverticulitis (8·6 versus 9·6 per cent; P = 0·610), complicated diverticulitis (4·0 versus 2·1 per cent; P = 0·079) and sigmoid resection (5·0 versus 2·5 per cent; P = 0·214). An initial pain score greater than 7, white blood cell count exceeding 13·5 × 109/l and previous diverticulitis at presentation were risk factors for adverse outcomes. Antibiotic treatment did not prevent adverse outcomes in patients at high risk of adverse events.Conclusion Observational management of acute uncomplicated diverticulitis is safe. Some statistical uncertainty remains, depending on the thresholds of clinical relevance, owing to small differences, but no subgroup that would benefit from antibiotic treatment was apparent.

- Robotic low anterior resection (R-LAR) for rectal cancer may decrease estimated blood loss compared with open low anterior resection (O-LAR). The aim of this study was to compare estimated blood loss and blood transfusion within 30 days after O-LAR and R-LAR. This was a retrospective matched cohort study based on prospectively registered data from Vastmanland Hospital, Sweden. The first 52 patients operated on using R-LAR for rectal cancer at Vastmanland Hospital were propensity score-matched 1:2 with patients who underwent O-LAR for age, sex, ASA (American Society of Anesthesiology physical classification system), and tumor distance from the anal verge. In total, 52 patients in the R-LAR group and 104 patients in the O-LAR group were included. Estimated blood loss was significantly higher in the O-LAR group compared with R-LAR: 582.7 ml (SD +/- 489.2) vs. 86.1 ml (SD +/- 67.7); p < 0.001. Within 30 days after surgery, 43.3% of patients who received O-LAR and 11.5% who received R-LAR were treated with blood transfusion (p < 0.001). As a secondary post hoc finding, multivariable analysis identified O-LAR and lower pre-operative hemoglobin level as risk factors for the need of blood transfusion within 30 days after surgery. Patients who underwent R-LAR had significantly lower estimated blood loss and a need for peri- and post-operative blood transfusion compared with O-LAR. Open surgery was shown to be associated with an increased need for blood transfusion within 30 days after low anterior resection for rectal cancer.
