- BACKGROUND: Tobacco smoking is a known risk factor for recurrence of Crohns disease after surgical resection. OBJECTIVE: This study assessed the effect of smoking cessation on long-term surgical recurrence after primary ileocolic resection for Crohns disease. DESIGN: A retrospective review of a prospectively maintained database was conducted. SETTINGS: Patient demographic data and medical and surgical details were combined from 2 specialist centers. After ethical approval, patients were contacted in case of missing data regarding smoking habit. PATIENTS: All patients undergoing ileocolic resection between 2000 and 2012 for histologically confirmed Crohns disease were included. Those with previous intestinal resection, strictureplasty for Crohns disease, leak after ileocolic resection, or who were never reversed were excluded. MAIN OUTCOME MEASURES: The primary end point was surgical recurrence measured by Kaplan-Meier survival analysis and secondary medical therapy at time of follow-up. RESULTS: Over a 12-year period, 290 patients underwent ileocolic resection. Full smoking data were available for 242 (83%) of 290 patients. There were 169 nonsmokers (70%; group 1), 42 active smokers at the time of ileocolic resection who continued smoking up to last follow-up (17%; group 2), and 31 (13%) who quit smoking after ileocolic resection (group 3). The median time of smoking exposure after ileocolic resection for group 3 was 3 years (interquartile range, 0-6 y), and median follow-up time for the whole group was 112 months (9 mo; interquartile range, 84-148 mo). Kaplan-Meier survival analysis showed a significantly higher surgical recurrence rate for group 2 compared with group 3 (16/42 (38%) vs 3/31 (10%); p = 0.02; risk ratio = 3.9 (95% CI, 1-12)). In addition, significantly more patients in group 2 without surgical recurrence received immunomodulatory maintenance therapy compared with group 3 (12/26 (46%) vs 4/28 (14%); p = 0.01; risk ratio = 3.2 (95% CI, 1-9)). LIMITATIONS: The study was limited by its retrospective design and small number of patients. CONCLUSIONS: Smoking cessation after primary ileocolic resection for Crohns disease may significantly reduce long-term risk of surgical recurrence and is associated with less use of maintenance therapy.

- BACKGROUND: Functional outcomes after ileoanal pouch creation have been studied; however, there is great variability in how relevant outcomes are defined and reported. More importantly, the perspective of patients has not been represented in deciding which outcomes should be the focus of research. OBJECTIVE: The primary aim was to create a patient-centered definition of core symptoms that should be included in future studies of pouch function. DESIGN: This was a Delphi consensus study. SETTING: Three rounds of surveys were used to select high-priority items. Survey voting was followed by a series of online patient consultation meetings used to clarify voting trends. A final online consensus meeting with representation from all 3 expert panels was held to finalize a consensus statement. PATIENTS: Expert stakeholders were chosen to correlate with the clinical scenario of the multidisciplinary team that cares for pouch patients, including patients, colorectal surgeons, and gastroenterologists or other clinicians. MAIN OUTCOME MEASURES: A consensus statement was the main outcome. RESULTS: One hundred ninety-five patients, 62 colorectal surgeons, and 48 gastroenterologists or nurse specialists completed all 3 Delphi rounds. Fifty-three patients participated in online focus groups. One hundred sixty-one stakeholders participated in the final consensus meeting. On conclusion of the consensus meeting, 7 bowel symptoms and 7 consequences of undergoing ileoanal pouch surgery were included in the final consensus statement. LIMITATIONS: The study was limited by online recruitment bias. CONCLUSIONS: This study is the first to identify key functional outcomes after pouch surgery with direct input from a large panel of ileoanal pouch patients. The inclusion of patients in all stages of the consensus process allowed for a true patient-centered approach in defining the core domains that should be focused on in future studies of pouch function.

Ileorectal Anastomosis Versus IPAA for the Surgical Treatment of Ulcerative Colitis: A Markov Decision Analysis
- 2020
-
Ingår i: Diseases of the Colon & Rectum. - : LIPPINCOTT WILLIAMS & WILKINS. - 0012-3706 .- 1530-0358. ; 63:9, s. 1276-1284

- BACKGROUND: Ileorectal anastomosis in patients with ulcerative colitis results in decreased postoperative morbidity and better functional outcome but leads to increased risk for rectal cancer compared with IPAA. OBJECTIVE: This study aims to compare ileorectal anastomosis with IPAA in ulcerative colitis by using a decision model. DESIGN: A Markov simulation model was designed to simulate clinical events of ileorectal anastomosis and IPAA over a time horizon of 40 years with time cycles of 1 year. All probabilities and utilities were derived from observational studies, identified after a systematic literature search using MEDLINE. Primary outcomes were life-years and quality-adjusted life-years. Deterministic and probabilistic sensitivity analyses were performed. SETTINGS: A decision model using Markov simulation was designed. PATIENTS: The base case was a 35-year-old patient with ulcerative colitis and a relatively preserved rectum. MAIN OUTCOMES MEASURES: The primary outcome measures were (quality-adjusted) life-years. RESULTS: The model resulted in lower life-years (36.22 vs 37.02) and higher quality-adjusted life-years (33.42 vs 31.57) for ileorectal anastomosis. This was confirmed after probabilistic sensitivity analysis. The model was sensitive to the utility of ileorectal anastomosis, IPAA, and end-ileostomy. A higher proportion of patients with ileorectal anastomosis will develop rectal cancer (7.6% vs 3.2%) and 43.5% of all patients with ileorectal anastomosis will end with an ileostomy as opposed to 23.0% of all patients with IPAA. LIMITATIONS: The study was limited by characteristics inherent to modeling studies, including assumptions necessary to build the model, data input based on best available but often limited evidence, and unavoidable extra- and interpolation of data. CONCLUSIONS: Ileorectal anastomosis was the preferred treatment option when quality-adjusted life-years were the outcome, with higher life-years for IPAA. This model highlights that both surgical strategies are useful in patients who have ulcerative colitis with a relatively spared rectum. See Video Abstract at http://links.lww.com/DCR/B249.

High Risk of Low Anterior Resection Syndrome in Long-term Follow-up After Anastomotic Leakage in Anterior Resection for Rectal Cancer
- 2022
-

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Low anterior resection syndrome is common after sphincter-sparing surgery, but it is unclear to what extent anastomotic leakage after anterior resection contributes to this condition. OBJECTIVE: The aim of this study is to assess the long-term effect of anastomotic leakage on the occurrence of major low anterior resection syndrome. DESIGN: This is a retrospective observational cohort study evaluating low anterior resection syndrome 4 to 11 years after index surgery. After propensity score-matching using the covariates sex, age, tumor stage, comorbidity, neoadjuvant treatment, extent of mesorectal excision, and defunctioning stoma at index surgery, the effect of anastomotic leakage on low anterior resection syndrome was investigated using relative risk and 95% CI. SETTINGS: This multicenter study included patients from 15 Swedish hospitals between 2007 and 2013. PATIENTS: Patients who underwent anterior resection for rectal cancer were included. MAIN OUTCOME MEASURES: Outcome measures included patient-reported major low anterior resection syndrome, obtained via a postal questionnaire that included a question on stoma status. RESULTS: Among 1099 patients, 653 (59.4%) responded in at a median of 83.5 (interquartile range 66 to 110) months postoperatively. After excluding patients with residual stoma or incomplete responses, 544 remained; of these, 42 had anastomotic leakage. Patients with anastomotic leakage were more likely to have major low anterior resection syndrome (66.7% [28/42]) than patients without leakage (45.8% [230/502]). After matching, anastomotic leakage was significantly related to major low anterior resection syndrome (relative risk 2.3; 95% CI 1.4-3.9) and the individual symptom of urgency (relative risk 2.1; 95% CI 1.1-4.1). LIMITATIONS: This study was limited by its retrospective observational study design. CONCLUSIONS: In long-term follow-up, major low anterior resection syndrome is common after anterior resection for rectal cancer. Anastomotic leakage appears to increase the risk of major low anterior resection syndrome, with urgency as a major contributing symptom. See Video Abstract at http://links.lww.com/DCR/B868.

- Background: It is still not clear whether anastomotic leakage after anterior resection for rectal cancer affects long-term functional outcome.Objective: To evaluate how anastomotic leakage following anterior resection for rectal cancer influences defecatory, urinary and sexual function.Design: In this retrospective population-based cohort study, patients were identified through the Swedish Colorectal Cancer Registry, which was also used for information on the exposure variable anastomotic leakage, and covariates.Settings: A nationwide register was used for including patients.Patients: All patients undergoing anterior resection for rectal cancer in Sweden from April 2011– June 2013 were included.Main Outcome Measures: Outcome was any defecatory, sexual or urinary dysfunction, assessed two years after surgery by a postal questionnaire. The association between anastomotic leakage and function was assessed in multivariable logistic and linear regression models, with adjustment for confounding.Results: Response rate was 82%, resulting in 1180 included patients. Anastomotic leakage occurred in 7.5%. A permanent stoma was more common among leak patients (44% vs. 9%; p<0.001). Leakage patients had an increased risk of aid use for fecal incontinence (OR 2.27; 95% CI 1.20-4.30) and reduced sexual activity (90% vs. 82%; p=0.003), while the risk of urinary incontinence was decreased (OR 0.53; 95% CI 0.31-0.90). A sensitivity analysis assuming that a permanent stoma was created due to anorectal dysfunction strengthened the negative impact of leakage on defecatory dysfunction.Limitations: Limitations include the used questionnaire not having been previously validated, underreporting of anastomotic leakage in the register, and small patient numbers in the analysis of sexual symptoms.Conclusions:a Anastomotic leakage was found to statistically significantly increase the risk of aid use due to fecal incontinence and reduced sexual activity, though the impact on defecatory dysfunction might be underestimated, as permanent stomas are sometimes fashioned due to anorectal dysfunction. Further research is warranted, especially regarding urogenital function.

- BACKGROUND: To avoid a permanent stoma, restorative surgery is performed after the colectomy. Previous studies have shown that less than half of patients with ulcerative colitis undergo restorative surgery.OBJECTIVE: The primary aim was to explore the association between socioeconomic status and restorative surgery after colectomy.DESIGN: This was a nationwide register-based cohort study.SETTINGS: The study was conducted in Sweden.PATIENTS: All Swedish patients with ulcerative colitis who underwent colectomy between 1990 and 2017 at the age of 15 to 69 years were included.MAIN OUTCOME MEASURES: The main outcome was restorative surgery, and the secondary outcome was failure of the reconstruction (defined as the need for a new ileostomy after the reconstruction or nonreversal of a defunctioning stoma within 2 years of the reconstruction). To calculate HRs for restorative surgery after colectomy, as well as failure after restorative surgery, multivariable Cox regression models were performed (adjusted for sex, year of colectomy, colorectal cancer diagnosis, education, civil status, country of birth, income (quartiles 1 to 4, where Q4 represents highest income), hospital volume, and stratified by age).RESULTS: In all, 5969 patients with ulcerative colitis underwent colectomy, and of those, 2794 (46.8%) underwent restorative surgery. Restorative surgery was more common in patients with a high income at the time of colectomy (quartile 1, reference; quartile 2, 1.09 (0.98-1.21); quartile 3, 1.20 (1.07-1.34); quartile 4, 1.27 (1.13-1.43)) and less common in those born in a Nordic country than in immigrants born in a non-Nordic country (0.86 (0.74-0.99)), whereas no association was seen with educational level and civil status. There was no association between socioeconomic status and the risk of failure after restorative surgery.LIMITATIONS: The study was restricted to register data.CONCLUSIONS: Restorative surgery in ulcerative colitis appears to be more common in patients with a high income and patients born in a non-Nordic country, indicating inequality in the provided care.

- BACKGROUND: Lymph node metastasis is the single most important prognostic risk factor for recurrence in patients with colon cancer who have undergone curative surgery. The routine method for detecting disseminated tumor cells in lymph nodes is microscopic examination of one or a few hematoxylin and eosin-stained tissue sections by a trained pathologist. This method, however, is insensitive mainly because less than 1% of the lymph node volume is examined, leading to misclassification.OBJECTIVE: This study aimed to investigate whether analysis of a selected group of biomarker mRNAs improves detection and characterization of lymph node metastases/micrometastases compared with the routine method.DESIGN: This study is a side-by-side comparison of biomarker mRNA analysis and histopathology of 185 lymph nodes from patients with colon cancer representing stages I to IV, and an investigation of the importance of lymph node tissue volume for tumor cell detection.SETTINGS: This is a collaborative study between a high-volume central hospital and a preclinical university institution.PATIENTS: Fifty-seven patients who had undergone tumor resection for colon cancer were included.MAIN OUTCOME MEASURES: The primary outcomes measured were mRNA copies per 18S rRNA copy of CEACAM5, KLK6, SLC35D3, POSTN, and MUC2 by multiplex assay and metastases/micrometastases detected by histopathology.RESULTS: The number of tumor cell-positive lymph nodes was 1.33-fold higher based on CEACAM5 mRNA levels compared with histopathological examination. Increasing the tissue volume analyzed for CEACAM5 levels from an 80-µm section to half a lymph node increased the number of positive nodes from 34 of 107 to 80 of 107 (p < 0.0001). Similarly, the number of positive nodes for the aggressiveness marker KLK6 increased from 9 of 107 to 24 of 107.LIMITATIONS: Only a limited number of individual lymph nodes per patient was available for analysis.CONCLUSIONS: mRNA analysis of CEACAM5, KLK6, and SLC35D3 improves the detection of tumor cells in lymph nodes from patients surgically treated for colon cancer, and, together with POSTN and MUC2, it further allows characterization of the tumor cells with respect to aggressiveness and the tumor cell environment.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: There have been conflicting reports regarding a protective effect of statin therapy after colon cancer surgery.OBJECTIVE: This study aimed to evaluate the association between statin therapy and the postoperative mortality following elective colon cancer surgery.DESIGN: This population-based cohort study is a retrospective analysis of prospectively collected data from the Swedish Colorectal Cancer Register.SETTINGS: Patient inclusion was achieved by inclusion through a nationwide register.PATIENTS: All adult patients undergoing elective surgery for colon cancer between the period of January 2007 and September 2016 were included in the study. Patients who had received and collected a prescription for statins pre- and postoperatively were allocated to the statin positive cohort.MAIN OUTCOME MEASURES: The primary and secondary outcomes of interest were 90-day all-cause mortality and 90-day cause-specific mortality.RESULTS: A total of 22,337 patients underwent elective surgery for colon cancer during the study period, of whom 6,494 (29%) were classified as statin users. Statin users displayed a significant survival benefit despite being older, having a higher comorbidity burden, and less fit for surgery. Multivariate analysis illustrated significant reductions in the incidence risk for 90-day all-cause mortality (Incidence Rate Ratio = 0.12, p < 0.001) as well as 90-day cause-specific deaths due to sepsis, multiorgan failure, or of cardiovascular and respiratory origin.LIMITATIONS: The limitations of this study include its observational retrospective design, restricting the ability to perform standardized follow-up of statin therapy. Confounding from other uncontrolled variables cannot be excluded.CONCLUSIONS: Statin users had a significant postoperative benefit regarding short-term mortality following elective colon cancer surgery in the current study, however, further research is needed to ascertain if this relationship is causal.
