- BACKGROUND AND AIMS: Non-operative management (NOM) of blunt liver trauma is currently, if possible, the preferred treatment of choice. The present study evaluates the experience of blunt liver injury in adults in a Swedish university hospital. MATERIAL AND METHODS: Forty-six patients with blunt liver trauma were treated from January 1994 through to December 2004. Patient charts were reviewed retrospectively to examine injury severity score (ISS), liver injury grade, diagnostics, treatment and outcome. RESULTS: Thirty-five patients (76%) were initially treated non-operatively and 11 (24%) patients had immediate surgery. In four (11%) patients, NOM failed and the patients required surgery 8-72 h after admission. Patients failing non-operative care had a significantly lower systolic blood pressure on admission as compared with patients with successful NOM (P = 0.001). Patients immediately operated upon had higher ISS (P < 0.001) and were haemodynamically unstable to a greater extent (P < 0.001) as compared with patients initially considered for NOM. Operated patients had increased transfusion requirements (P < 0.001), longer total hospital stay (P = 0.011) and stay in the intensive care unit (ICU) unit (P < 0.001) as compared with NOM. One immediately operated and one failed NOM died (total mortality 4%). Seventeen patients in the NOM group were successfully treated without surgery despite the presence of at least one described risk factor. CONCLUSIONS: Most patients with blunt liver trauma can be treated without surgery, and non-operative management may be performed even in the presence of established risk factors.

Fast-track programmes for hepatopancreatic resections: where do we stand?
- 2011
-
In: HPB. - : Elsevier BV. - 1477-2574 .- 1365-182X. ; 13:12, s. 833-838
-
Journal article (peer-reviewed)abstract
- Background: Fast-track (FT) programmes represent a series of multimodal concepts that may reduce surgical stress and speed up convalescence after surgery. The aim of this systematic review was to evaluate FT programmes for patients undergoing hepatopancreatic surgery. Methods: PubMed, Embase and the Cochrane Library databases were searched for studies of FT vs. conventional recovery strategies for liver and pancreatic resections. Results: For liver surgery, three cohort studies were included. Primary hospital stay was significantly reduced after FT care in two of the three studies. There were no significant differences in rates of readmission, morbidity and mortality. For pancreatic surgery, three cohort studies and one case-control study were included. Primary hospital stay was significantly shorter after FT care in three out of the four studies. One study reported a significantly decreased readmission rate (7% vs. 25%; P= 0.027), and another study showed lower morbidity (47.2% vs. 58.7%; P < 0.01) in favour of the FT group. There was no difference in mortality between the FT and control groups. Conclusions: FT rehabilitation for liver and pancreatic surgical patients is feasible. Future investigation should focus on optimizing individual elements of the FT programme within the context of liver and pancreatic surgery.

Magnetic resonance imaging flowmetry demonstrates portal vein dilatation subsequent to oxaliplatin therapy in patients with colorectal liver metastasis
- 2013

Journal article (peer-reviewed)abstract
- Objectives: Sinusoidal injury (SI) after oxaliplatin-based therapies for colorectal liver metastasis (CRLM) can increase postoperative morbidity. Preoperative methods to estimate SI are lacking. The aim of this study was to identify SI by evaluating portal vein haemodynamics. Methods: Magnetic resonance imaging flowmetry (MRIF) was used to estimate portal vein haemodynamics in 29 patients with CRLM before liver surgery. Sinusoidal injury was evaluated from resected non-tumorous liver parenchyma according to the combined vascular injury (CVI) score of ≥3. Results: All patients with SI (six of 29) received oxaliplatin; however, a significant association could not be proven (P= 0.148). Oxaliplatin-treated patients showed portal vein dilatation in both the SI and non-SI groups compared with patients who had not received oxaliplatin (Bonferroni corrected P= 0.003 and P= 0.039, respectively). Mean portal velocity tended to be lower in patients with SI compared with oxaliplatin-treated patients without SI (Bonferroni corrected P= 0.087). A mean portal velocity of ≤14.35 cm/s together with a cross-section area of ≥1.55 cm2 was found to predict SI with sensitivity of 100% and specificity of 78%. Conclusions: Oxaliplatin treatment was associated with portal vein dilatation. Patients with SI showed a tendency towards decreased mean portal flow velocity. This may indicate that SI is associated with an increased resistance to blood flow in the liver parenchyma. Portal vein haemodynamic variables estimated by MRIF can identify patients without SI non-invasively.

Are liver function tests, pancreatitis and cholecystitis predictors of common bile duct stones? : Results of a prospective, population-based, cohort study of 1171 patients undergoing cholecystectomy
- 2011
-
In: HPB. - : Elsevier BV. - 1365-182X .- 1477-2574. ; 13:8, s. 519-527
-
Journal article (peer-reviewed)abstract
- Objective: The purpose of this study was to explore the accuracy of elevated liver function values, age, gender, pancreatitis and cholecystitis as predictors of common bile duct stones (CBDS). Methods: All patients operated on for gallstone disease over a period of 3 years in a Swedish county of 302 564 citizens were registered prospectively. Intraoperative cholangiography (IOC) was used to detect CBDS. Results: A total of 1171 patients were registered; 95% of these patients underwent IOC. Common bile duct stones were found in 42% of patients with elevated liver function values, 20% of patients with a history of pancreatitis and 9% of patients with cholecystitis. The presence of CBDS was significantly predicted by elevated liver function values, but not by age, gender, history of acute pancreatitis or cholecystitis. A total of 93% of patients with normal liver function tests had a normal IOC. The best agreement between elevated liver function values and CBDS was seen in patients undergoing elective surgery without a history of acute pancreatitis or cholecystitis. Conclusions: Although alkaline phosphatase (ALP) and bilirubin levels represented the most reliable predictors of CBDS, false positive and false negative values were common, especially in patients with a history of cholecystitis or pancreatitis, which indicates that other mechanisms were responsible for elevated liver function values in these patients.

Acute pancreatitis - from cellular signalling to complicated clinical course.
- 2007
-
In: HPB. - : Elsevier BV. - 1477-2574 .- 1365-182X. ; 9:6, s. 414-420
-
Journal article (peer-reviewed)abstract
- Acute pancreatitis (AP) is a common disease that has a mild to moderate course in most cases. During the last decade, a change in diagnostic facilities as well as improved intensive care have influenced both morbidity and mortality in AP. Still, however, a number of controversies and unresolved questions remain regarding AP. These include prognostic factors and how these may be used to improve outcome, diagnostic possibilities, their indications and optimal timing, and the systemic inflammatory reaction (systemic inflammatory response syndrome - SIRS) and its effect on the concomitant course of the disease and potential development of organ failure. The role of the gut has been suggested to be important in severe AP, but has recently been somewhat questioned. Despite extensive research, pharmacological and medical intervention of proven clinical value is scarce. Various aspects on surgical interventions, including endoscopic sphincterotomy, cholecystectomy and necrosectomy, as regards indications and timing, will be reviewed. Last, but not least, are the management of late complications and long-term outcome for patients with especially severe AP.

Journal article (peer-reviewed)abstract
- Introduction. Iatrogenic bile duct lesions following cholecystectomy represent a feared complication occurring in up to 0.9%. The aim of the present study was to estimate the total cost associated with both minor and major bile duct injuries. Material and methods. Detailed information on 24 consecutive patients, out of which 14 were considered to have minor and 10 patients considered as having major bile duct injury, provided the underlying information that rendered calculations on average individual costs for both groups of injuries. Results and discussion. Calculating individual costs for minor and major bile duct injuries with actual incidences of cholecystectomies performed and the incidence of iatrogenic bile duct injury demonstrated that the total costs, including in-hospital cost, sick leave and loss of production, were substantial. For the management of minor bile duct injuries costs were within the range of 136,787-159,585 EUR and for the management of major bile duct injuries from 336,903-449,204 EUR per million inhabitants and year. The total costs for the management of all types of bile duct injuries were thus within the range of 473,690-608,789 EUR per million inhabitants annually for the society.

Immunomodulation in surgical practise
- 2006
-
In: HPB. - : Elsevier BV. - 1477-2574 .- 1365-182X. ; 8:2, s. 116-123
-
Journal article (peer-reviewed)abstract
- Background. Immunomodulation may represent a potential way to improve surgical outcome. These types of interventions should be based on detailed knowledge of the underlying mechanisms involved. The aim of the present review is to summarize some experience on the acute phase response, potential ways of intervention and experiences from critical illness and HPB disease. Discussion. Mechanisms of the acute phase response are discussed including the individual parameters and local changes that take part. Mechanisms involved in failure of the gut barrier are presented and include changes in gut barrier permeability, effects on gut-associated immunocompetent cells, and systemic implications. As examples of HPB disease, mechanisms of the acute phase response and potential ways of intervention in obstructive jaundice and acute pancreatitis are discussed. Nutritional pharmacology and lessons learned from immunomodulation and immunonutrition in critical illness and major abdominal surgery, including upper GI and HPB surgery, are referred to. Overall, immunomodulation represents a potential tool to improve results but requires a thorough mapping of underlying mechanisms in order to achieve individualized treatment or prevention based on patients' specific needs.

Preoperative staging and evaluation of resectability in pancreatic ductal adenocarcinoma.
- 2004
-
In: HPB. - : Elsevier BV. - 1477-2574 .- 1365-182X. ; 6:1, s. 5-12
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Cancer of the pancreas is a common disease, but the large majority of patients have tumours that are irresectable at the time of diagnosis. Moreover, patients whose tumours are clearly beyond surgical cure are best treated non-operatively, if possible, by relief of biliary obstruction and percutaneous biopsy to confirm the diagnosis and then consideration of oncological treatment, notably chemotherapy. These facts underline the importance of a standard protocol for the preoperative determination of operability (is it worth operating?) and resectability (is there a chance that the tumour can be removed?). Recent years have seen the advent of many new techniques, both radiological and endoscopic, for the diagnosis and staging of pancreatic cancer. It would be impracticable in time and cost to submit every patient to every test. This review will evaluate the available techniques and offer a possible algorithm for use in routine clinical practice. DISCUSSION: In deciding whether to operate with a view to resecting a pancreatic cancer, the surgeon must take into account factors related to the patient, the tumour and the institution and team entrusted with the patient's care. Patient-related factors include age, general health, pain and the presence or absence of malnutrition and an acute phase inflammatory response. Tumour-related factors include tumour size and evidence of spread, whether to adjacent organs (notably major blood vessels) or further afield. Hospital-related factors chiefly concern the volume of pancreatic cancer treated and thus the experience of the whole team. Determination of resectability is heavily dependent upon detailed imaging. Nowadays conventional ultrasonography can be supplemented by endoscopic, laparoscopic and intra-operative techniques. Computed tomography (CT) remains the single most useful staging modality, but MRI continues to improve. PET scanning may demonstrate unsuspected metastases and likewise laparoscopy. Diagnostic cholangiography can be performed more easily by MR techniques than by endoscopy, but ERCP is still valuable for preoperative biliary decompression in appropriate patients. The role of angiography has declined. Percutaneous biopsy and peritoneal cytology are not usually required in patients with an apparently resectable tumour. The prognostic value of tumour marker levels and bone marrow biopsy is yet to be established. Preoperative chemotherapy or chemoradiation may have a role in down-staging an irresectable tumour sufficiently to render it resectable. Selective use of diagnostic laparoscopy staging is potentially helpful in determination of resectability. Laparotomy remains the definitive method for determining the resectability of pancreatic cancer, with or without portal vein resection, and should be undertaken in suitable patients without clear-cut evidence of irresectability.

Heterogeneity of management practices surrounding operable gallbladder cancer – results of the OMEGA-S international HPB surgical survey
- 2022
-
In: HPB. - : Elsevier BV. - 1365-182X. ; 24:11, s. 2006-2012
-
Journal article (peer-reviewed)abstract
- Background: Gallbladder cancer (GBC) is an aggressive, uncommon malignancy, with variation in operative approaches adopted across centres and few large-scale studies to guide practice. We aimed to identify the extent of heterogeneity in GBC internationally to better inform the need for future multicentre studies. Methods: A 34-question online survey was disseminated to members of the European-African Hepatopancreatobiliary Association (EAHPBA), American Hepatopancreatobiliary Association (AHPBA) and Asia–Pacific Hepatopancreatobiliary Association (A-PHPBA) regarding practices around diagnostic workup, operative approach, utilization of neoadjuvant and adjuvant therapies and surveillance strategies. Results: Two hundred and three surgeons responded from 51 countries. High liver resection volume units (>50 resections/year) organised HPB multidisciplinary team discussion of GBCs more commonly than those with low volumes (p < 0.0001). Management practices exhibited areas of heterogeneity, particularly around operative extent. Contrary to consensus guidelines, anatomical liver resections were favoured over non-anatomical resections for T3 tumours and above, lymphadenectomy extent was lower than recommended, and a minority of respondents still routinely excised the common bile duct or port sites. Conclusion: Our findings suggest some similarities in the management of GBC internationally, but also specific areas of practice which differed from published guidelines. Transcontinental collaborative studies on GBC are necessary to establish evidence-based practice to minimise variation and optimise outcomes. © 2022 International Hepato-Pancreato-Biliary Association Inc.

Journal article (peer-reviewed)abstract
- Background: Pancreatic cancer remains a leading cause of cancer-related death. To individualise management and improve survival, more accurate prognostic models are needed.Methods: All patients resected for pancreatic ductal adenocarcinoma in a tertiary Swedish centre during 2009-2019 were thoroughly analysed with regards to pathological and clinical parameters including tumour grade, resection margin status, para-aortic lymph node engagement (node station 16), and systemic treatment.Results: The study cohort included 275 patients. Overall median survival was 21.2 months (95% CI 17.5-24.8). Year of resection, margin status (R1 subdivided into R1(1mm)/R1(ink)), perineural invasion, differentiation grade, TNM stage, and adjuvant therapy were independent factors with significant impact on survival. Margin status also significantly affected recurrence-free survival and relapse patterns, with local and peritoneal relapses being associated with R1-status (p < 0.001 and p = 0.007). Presence of paraaortic lymph node metastases was associated with shorter recurrence-free survival as compared to N1 status only.Conclusion: Survival in resected pancreatic cancer is improving over time. Resection margin status is a key factor affecting recurrence patterns and prognosis. Given the poor recurrence-free survival in node station 16 metastasised patients, the rational for resection remains in doubt, and improved treatment strategies for this patient group is necessary.

Is it safe to administer neoadjuvant chemotherapy to patients undergoing hepatectomy for intrahepatic cholangiocarcinoma? : ACS-NSQIP propensity-matched analysis
- 2022
-
In: HPB. - : Elsevier. - 1365-182X .- 1477-2574. ; 24:9, s. 1535-1542

Journal article (peer-reviewed)abstract
- Background: The use of neoadjuvant chemotherapy (NAC) in patients with intrahepatic chol-angiocarcinoma (iCCA) is increasing. The objective of this study was to compare the 30-day post-operative complications and length-of-stay (LOS) between patients undergoing hepatectomy for iCCA with and without NAC.Methods: A retrospective study was conducted using the ACS-NSQIP database queried from 2014 to 2018. Patients with NAC receipt were propensity-score matched into 1:3 ratio with controls using the greedy-matching algorithm and a caliper of 0.2. Logistic and Poisson regression models were used to estimate the effect sizes.Results: A total of 1508 patients who underwent hepatectomy for iCCA were included. 706 patients remained after matching and balance were achieved. The NAC group had 110 (60.1%) complications vs. 289 (55.3%) complications in the non-NAC group (p = 0.29). NAC was not associated with worse 30-day postoperative complications [OR 1.24, 95% CI: 0.87-1.76; p = 0.24]. Post-operative LOS in the NAC group was 8.56 days (mean, SD 7.4) vs. non-NAC group 9.27 days (mean, SD 8.41, p = 0.32). NAC was not associated with longer post-operative LOS [RR 0.93, 95% CI:0.80, 1.08; p = 0.32].Conclusion: NAC may be safely administered without increasing the risk of 30-day complications or post-operative hospital LOS.

Hepatopancreatoduodenectomy –a controversial treatment for bile duct and gallbladder cancer from a European perspective
- 2020
-
In: HPB. - : Elsevier BV. - 1365-182X. ; 22:9, s. 1339-1348
-
Journal article (peer-reviewed)abstract
- Background: Hepatopancreatoduodenectomy (HPD) is an aggressive operation for treatment of advanced bile duct and gallbladder cancer associated with high perioperative morbidity and mortality, and uncertain oncological benefit in terms of survival. Few reports on HPD from Western centers exist. The purpose of this study was to evaluate safety and efficacy for HPD in European centers. Method: Members of the European-African HepatoPancreatoBiliary Association were invited to report all consecutive patients operated with HPD for bile duct or gallbladder cancer between January 2003 and January 2018. The patient and tumor characteristics, perioperative and survival outcomes were analyzed. Results: In total, 66 patients from 19 European centers were included in the analysis. 90-day mortality rate was 17% and 13% for bile duct and gallbladder cancer respectively. All factors predictive of perioperative mortality were patient and disease-specific. The three-year overall survival excluding 90-day mortality was 80% for bile duct and 30% for gallbladder cancer (P = 0.013). In multivariable analysis R0-resection had a significant impact on overall survival. Conclusion: HPD, although being associated with substantial perioperative mortality, can offer a survival benefit in patient subgroups with bile duct cancer and gallbladder cancer. To achieve negative resection margins is paramount for an improved survival outcome.

ALPPS as a salvage procedure after insufficient future liver remnant hypertrophy following portal vein occlusion
- 2017
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 19:12, s. 1126-1129
-
Journal article (peer-reviewed)abstract
- Background: A minimum future liver remnant (FLR) of 30% is required to avoid post hepatectomy liver failure (PHLF). Portal vein occlusion (PVO) is the main strategy to induce hypertrophy of the FLR, but some patients will not reach sufficient FLR hypertrophy to enable resection. Recently ALPPS has emerged as a "Salvage Procedure" for PVO failure. The aim of this study was to report the short term outcomes of ALPPS following PVO failure. Methods: A retrospective analysis of patients enrolled within the international ALPPS Registry between October 2012 and November 2015 (NCT01924741) was performed. Patients with documented PVO failure were included. The outcomes reported included feasibility, FLR growth rate and safety of ALPPS. Complications were recorded as per Clavien-Dindo classification. Results: From 510 patients enrolled in the Registry there were 22 patients with previous PVO failure. Two patients were excluded due to missing data and twenty patients were analysed. All of them completed the proposed ALPPS with a medium FLR increase of 88% (23-115%) between two stages and no 90-day mortality. Conclusion: In experienced centers, ALPPS following PVO failure is feasible and safe. The FLR hypertrophy was similar to other ALPPS series. ALPPS is a potential rescue strategy after PVO failure.

Journal article (peer-reviewed)abstract
- BackgroundThe optimal treatment strategy for patients with synchronous colorectal liver metastases is unclear. The aim of this study was to compare the outcome of the simultaneous, liver-first, and colorectal-first surgical approaches. MethodsAll consecutive patients with synchronous colorectal liver metastases who underwent liver resection with curative intent were included. Data were collected from local databases. Patient and tumour specific characteristics were retrieved, and clinicopathological factors were analysed. A Cox regression model was constructed, and a subgroup intention-to-treat analysis was performed after propensity score matching. ResultsA total of 658 patients were included in the analysis. Ninety-two patients had a simultaneous resection, 163 patients had liver-first, and 403 patients had a colorectal-first approach. After matching, two balanced groups between the simultaneous and liver-first groups were created with 58 patients in each. There were no differences in post-operative complications defined as Clavien-Dindo 3a (p=0.992), and >3a (p=0.999). There were no differences in overall survival between the groups (stratified log rank p=0.455). The median overall survival for liver-first was 42.2 (26.3-58.2) months, and for the simultaneous groups, 56.2 (47.1-65.4). ConclusionThe simultaneous approach was not associated with worse overall survival compared to a staged approach, and had comparable morbidity and mortality.

The prognostic value of C-reactive protein and albumin in patients undergoing resection of colorectal liver metastases. A retrospective cohort study
- 2021
-
In: HPB. - : Elsevier. - 1365-182X .- 1477-2574. ; 23:6, s. 970-978
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The systemic inflammation-based Glasgow Prognostic Score (GPS) and modified GPS (mGPS), as measured by preoperative C-reactive protein (CRP) and albumin, correlate with poor survival in several cancers. This study evaluates the prognostic value of these scores in patients with colorectal liver metastases (CRLM).METHODS: This retrospective study assessed the prognostic role of preoperatively measured GPS and mGPS in patients undergoing liver resection because of CRLM. Clinicopathological data were retrieved from local databases. The prognostic value of GPS and mGPS were compared and a Cox regression model was used to find independent predictors of overall survival.RESULTS: In total, 849 consecutive patients between January 2005 and December 2015 were included. Patients with GPS 0 had a median survival of 70 months compared to 49 months in patients with GPS 1, and 27 months in patients with GPS 2. Multivariable analyses showed that GPS 1 (HR = 1.51, 95%CI [1.14-2.01]) and GPS 2 (HR = 2.78, 95%CI [1.79-4.31]), after correction for age >70 years (HR = 1.75 [1.36-2.26]), and extended resection (HR = 2.53, 95%CI[1.79-3.58]), were associated with poor overall survival.CONCLUSION: A preoperative GPS is an independent prognostic factor in patients with CRLM, and appears to be a better prognostic tool than mGPS.

Sarcopenia predicts reduced liver growth and reduced resectability in patients undergoing portal vein embolization before liver resection-A DRAGON collaborative analysis of 306 patients
- 2022
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 24:3, s. 413-421

Journal article (peer-reviewed)abstract
- Background: After portal vein embolization (PVE) 30% fail to achieve liver resection. Malnutrition is a modifiable risk factor and can be assessed by radiological indices. This study investigates, if sarcopenia affects resectability and kinetic growth rate (KGR) after PVE. Methods: A retrospective study was performed of the outcome of PVE at 8 centres of the DRAGON collaborative from 2010 to 2019. All malignant tumour types were included. Sarcopenia was defined using gender, body mass and skeletal muscle index. First imaging after PVE was used for liver volumetry. Primary and secondary endpoints were resectability and KGR. Risk factors impacting liver growth were assessed in a multivariable analysis. Results: Eight centres identified 368 patients undergoing PVE. 62 patients (17%) had to be excluded due to unavailability of data. Among the 306 included patients, 112 (37%) were non-sarcopenic and 194 (63%) were sarcopenic. Sarcopenic patients had a 21% lower resectability rate (87% vs. 66%, p < 0.001) and a 23% reduced KGR (p = 0.02) after PVE. In a multivariable model dichotomized for KGR >2.3% standardized FLR (sFLR)/week, only sarcopenia and sFLR before embolization correlated with KGR. Conclusion: In this largest study of risk factors, sarcopenia was associated with reduced resectability and KGR in patients undergoing PVE.

Incisional hernias following gallstone surgery : A population-based study
- 2020
-
In: HPB. - : Elsevier. - 1365-182X .- 1477-2574. ; 22:12, s. 1775-1781
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The aim of this study was to determine the incidence of incisional hernia (IH) in a population-based cohort following gallstone surgery and to identify associated risk factors.METHODS: All cholecystectomies registered in the Swedish register for cholecystectomy and ERCP from 2006 to 2014 were identified. Data regarding post-procedural development of IH was obtained from the National Patient Register.RESULTS: A total of 81 964 cholecystectomies were identified. A laparoscopic, open, and minilaparotomy technique was used in 70 031, 10 379 and 1554 procedures, respectively. The five-year cumulative incidence of IH was 1.04 per cent in the laparoscopic group, 3.37 per cent in the open group, and 2.11 per cent in the minilaparotomy group. Obesity (hazard ratio (HR) 4.11, 95 per cent confidence interval [CI] 3.37 to 5.01), open surgical technique (HR 2.97, CI 2.57 to 3.42), liver cirrhosis (HR 2.95, CI 1.58 to 5.51), chronic kidney disease (HR 1.95, CI 1.19 to 3.21), minilaparotomy (HR 1.79, CI 1.23 to 2.60), age > median (HR 1.43, CI 1.25 to 1.65), and chronic pulmonary disease (HR 1.28, CI 1.05 to 1.57) were found to significantly predict the development of IH.CONCLUSION: Laparoscopic cholecystectomy comes with a lower risk of IH compared to open techniques.

Management strategies and treatment results of pediatric choledochal malformations in the Nordic countries
- 2020
-
In: HPB. - : Elsevier BV. - 1365-182X. ; 22:1, s. 161-168
-
Journal article (peer-reviewed)abstract
- Background: Incidence and long-term outcomes of choledochal malformations (CMs) in children remain unclear. Methods: Clinical characteristics, operative details, complications, and follow-up data were collected from eight pediatric surgical centers in Sweden, Norway, Denmark, and Finland, which also answered a questionnaire addressing management practices. Results: During 2000–2017, 126 pediatric CMs were diagnosed, corresponding an incidence of 1:37,400. Diagnostic, treatment, and follow-up practices varied markedly. Of patients with complete clinical data (n = 119), 85% and 11% had type I and IV CMs and were managed by open hepaticojejunostomy at median age of 2.5 (interquartile range 0.46–5.8) years. Associated malformations were more common in fusiform and type IV (23%) than cystic CMs (8%, p = 0.043). Pancreaticobiliary maljunction was more frequently confirmed in patients presenting with pancreatitis (26% vs. 7%, p = 0.005) and with fusiform CMs (56% vs. 25%, p = 0.001). Cholangitis/pancreatitis episodes, occurring in 12% during postoperative follow-up of 4.0 (2.0–7.9) years, associated with longer surveillance (OR 1.32, 95% CI 1.13–1.54, p < 0.001). However, only two thirds of centers continued follow-up until adulthood. No malignancies were reported. Conclusions: CM incidence was higher than traditionally reported among Western populations. Although open hepaticojejunostomy carries good short-term outcomes, long-term morbidity is noteworthy. Standardized evidence-based management strategies and long-term follow-up are encouraged.

Hepatic encephalopathy verified by psychometric testing and EEG in cirrhotic patients : Effects of mesocaval interposition shunt or sclerotherapy
- 2005
-
In: HPB. - : Elsevier BV. - 1365-182X .- 1477-2574. ; 7:1, s. 65-72
-
Journal article (peer-reviewed)abstract
- Background. The aim of this randomised prospective study was to evaluate hepatic encephalopathy after mesocaval interposition shunt operation and after repeated endoscopic sclerotherapy. Methods. Forty-five patients with bleeding oesophageal varices due to liver cirrhosis were randomised to the two treatment groups, 24 to the shunt group and 21 to the sclerotherapy group. The patients were evaluated preoperatively regarding blood tests, hepatic encephalopathy as measured by electroencephalogram with spectral analysis and by a battery of psychometric tests. The direction of portal flow in the shunt group was investigated by shunt phlebography and ultrasonography with Doppler. During follow-up the same investigations were performed twice at median 6.7 and 14.7 months after operation. Results. No statistically significant difference was found during follow-up regarding blood tests and electroencephalography with spectral analysis. Although the preoperative psychometric tests showed that the shunt group performed significantly better than the sclerotherapy group, the first follow-up showed that the shunt group performed statistically worse than the sclerotherapy group in seven of the tests: Synonyms (measuring verbal ability), Block Design Test (measuring visuo-spatial ability), Memory for Design Test, Error Score (measuring memory function), Revised Visual Retention Test, correct answers and the same test error answers (measuring visuo-spatial memory, ability and immediate memory), Digit Symbol Test (measuring perceptual ability) and Trial Making Test B (measuring cognitive motor abilities). Conclusions. Patients treated by mesocaval interposition shunt showed a progressive general reduction in psychometric performance compared with patients treated with repeated sclerotherapy, in whom a general intellectual improvement was observed. This finding corresponds to the reverse direction of the preoperative portal flow to a hepatofugal pattern at first follow-up and at 12 months among two-thirds of the patients. © 2005 Taylor & Francis Group Ltd.

Evidence-based medicine in HBP surgery: Is there any?
- 2005
-
In: HPB. - : Elsevier BV. - 1477-2574 .- 1365-182X. ; 7:3, s. 197-200
-
Journal article (peer-reviewed)abstract
- Background. Evidence-based medicine (EBM) has become widely accepted as a basis for clinical decision in many fields of medicine. This review examines the specific role of EBM in hepato-biliary and pancreatic (HBP) surgery. EBM relies on four main sources, including clinical guidelines, meta-analyses, primary information and clinical experience. Randomized controlled trials (RCTs) constitute the cornerstone of EBM and a recent study reported that there are relatively few RCTs evaluating the effectiveness of surgical therapies and procedures (1,530 out of 45,342 or 3.4% in five leading surgical journals) and only a few in HBP surgery. Although the effort must be to implement EBM as far as possible in HBP surgery, there are several obstacles to conducting RCTs in HBP surgery, including problems associated with standardization of surgical skills, sham-operations often impossible to perform, and the general applicability of specific findings may be uncertain.Discussion. This paper will provide two relevant examples of EBM in HBP surgery in patients with hepatic metastases and pancreatic adenocarcinoma, illustrating some problems but also the potential of introducing EBM in HBP surgery. In the future, our effort must be devoted to implementing EBM in applicable areas of HBP surgery but also remembering that in certain areas accumulated knowledge from observational studies, including drainage of abscesses and surgical treatment of intestinal obstruction, may have similar or even higher clinical value than RCTs.

Complications and chemotherapy have little impact on postoperative quality of life after pancreaticoduodenectomy - a cohort study
- 2022
-
In: HPB. - : Elsevier Science Ltd. - 1365-182X .- 1477-2574. ; 24:9, s. 1464-1473
-
Journal article (peer-reviewed)abstract
- Background: With the poor prognosis of pancreatic cancer and the high rate of postoperative complications after pancreaticoduodenectomy, it is important to evaluate how the operation affects patients quality of life. Methods: This single-centre study included all patients undergoing pancreaticoduodenectomy from 2006 to 2016. Quality of life was measured with two questionnaires preoperatively, and at 6 and 12 months postoperatively. Comparisons between groups were made using a linear mixed models analysis. Results: Of 279 patients planned for pancreaticoduodenectomy, 245 underwent the operation. The postoperative response rates were all 80% or more. Differences were found in one domain between the early and late time periods and three domains between patients receiving and not receiving adjuvant chemotherapy. No significant differences were found between patients with and without severe postoperative complications. However, the demographic variables of age group, sex, preoperative diabetes and smoking all exerted a significant impact on postoperative quality of life. Conclusion: While little or no impact was shown for the factors of postoperative complications, time period and adjuvant chemotherapy, demographic data, such as age, sex, preoperative diabetes and smoking, had considerable impacts on postoperative quality of life after pancreaticoduodenectomy.

Laparoscopic distal pancreatectomy is more cost-effective than open resection: results from a Swedish randomized controlled trial
- 2023
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 25:8, s. 972-979
-
Journal article (peer-reviewed)abstract
- BackgroundLaparoscopic distal pancreatectomy is being implemented worldwide. The aim of this study was to perform a cost-effectiveness analysis from a health care perspective.MethodsThis cost-effectiveness analysis was based on the randomized controlled trial LAPOP, where 60 patients were randomized to open or laparoscopic distal pancreatectomy. For the follow-up of two years, resource use from a health care perspective was recorded, and health-related quality of life was assessed using the EQ-5D-5L. The per-patient mean cost and quality-adjusted life years (QALYs) were compared using nonparametric bootstrapping.ResultsFifty-six patients were included in the analysis. The mean health care costs were lower, €3863 (95% CI: -€8020 to €385), for the laparoscopic group. Postoperative quality of life improved with laparoscopic resection and resulted in a gain in QALYs of 0.08 (95% CI: −0.09 to 0.25). The laparoscopic group had lower costs and improved QALYs in 79% of bootstrap samples. With a cost-per-QALY threshold of €50 000, 95.4% of the bootstrap samples were in favour of laparoscopic resection.ConclusionLaparoscopic distal pancreatectomy is associated with numerically lower health care costs and improvements in QALYs compared with the open approach. The results support the ongoing transition from open to laparoscopic distal pancreatectomies.

Symptoms and life changes after total pancreatectomy : a qualitative study
- 2023
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 25:2, s. 269-277
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Total pancreatectomy (TP) is a major surgical procedure that involves lifelong exocrine and endocrine pancreatic insufficiency. Qualitative evidence is sparse regarding patients' experiences after the operation. The aim of this study was to explore patients' experiences of symptoms that occur after TP and how these symptoms affect their health and life situations.METHODS: A qualitative design with prospective consecutive sampling and an inductive thematic analysis was used. Semistructured interviews were postoperatively performed at 6-9 months with 20 patients undergoing TP in two university hospitals in Sweden.RESULTS: Two main themes emerged from the analysis: "Changes in everyday life" and "Psychological journey". Patients experienced symptoms related to diabetes as the major life change after the operation, and they were also limited by symptoms of exocrine insufficiency, difficulties with food intake and physical weakness. In the psychological journey that patients underwent, the support received from family, friends and the health care system was important. Moreover, patients experienced a general need for more extensive information, especially regarding diabetes.CONCLUSION: Patients experience a lack of sufficient support and education after TP, particularly concerning their diabetes. Further efforts should be undertaken to improve information and the organization of diabetes care for this patient group.

Minimally invasive versus open distal pancreatectomy: an individual patient data meta-analysis of two randomized controlled trials
- 2021
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 23:3, s. 323-330
-
Research review (peer-reviewed)abstract
- Background: Minimally invasive distal pancreatectomy (MIDP) has been suggested to reduce postoperative outcomes as compared to open distal pancreatectomy (ODP). Recently, the first randomized controlled trials (RCTs) comparing MIDP to ODP were published. This individual patient data meta analysis compared outcomes after MIDP versus ODP combining data from both RCTs. Methods: A systematic literature search was performed to identify RCTs on MIDP vs. ODP, and individual patient data were harmonized. Primary endpoint was the rate of major (Clavien-Dindo > III) complications. Sensitivity analyses were performed in high-risk subgroups. Results: A total of 166 patients from the LEOPARD and LAPOP RCTs were included. The rate of major complications was 21% after MIDP vs. 35% after ODP (adjusted odds ratio 0.54; p = 0.148). MIDP significantly reduced length of hospital stay (6 vs. 8 days, p = 0.036), and delayed gastric emptying (4% vs. 16%, p = 0.049), as compared to ODP. A trend towards higher rates of postoperative pancreatic fistula was observed after MIDP (36% vs. 28%, p = 0.067). Outcomes were comparable in high-risk subgroups. Conclusion: This individual patient data meta-analysis showed that MIDP, when performed by trained surgeons, may be regarded as the preferred approach for distal pancreatectomy. Outcomes are improved after MIDP as compared to ODP, without obvious downsides in high-risk subgroups.

Journal article (peer-reviewed)abstract
- Background: There is a lack of consensus on the definition of upfront resectability and use of perioperative systemic therapy for colorectal liver metastases (CRLM). This survey aimed to summarize the current treatment strategies for upfront resectable CRLM throughout Europe. Methods: A survey was sent to all members of the European-African Hepato-Pancreato-Biliary Association to gain insight into the current views on resectability and the use of systemic therapy for upfront Results: The survey was completed by 87 surgeons from 24 countries. The resectability of CRLM is mostly based on the volume of the future liver remnant, while considering tumor biology. Thermal ablation was considered as an acceptable adjunct to resection in parenchymal-sparing CRLM surgery by 77 % of the respondents. A total of 40.2 % of the respondents preferred standard perioperative systemic Conclusion: Among the participating European hepato-pancreato-biliary surgeons, there is a high degree of consensus on the definition of CRLM resectability. However, there is much variety in the use of adjunctive thermal ablation. Major variations persist in the use of perioperative systemic therapy in cases of upfront resectable CRLM, stressing the need for further evidence and a consensus.

- 2022
-
In: HPB. - : Elsevier Science Ltd. - 1365-182X .- 1477-2574. ; 24:7, s. 1091-1099
-
Journal article (peer-reviewed)abstract
- Background: This study compared postoperative outcomes and survival rates of patients who un-derwent simultaneous or staged resection for synchronous colorectal cancer liver metastases. Methods: Between 2005 and 2018, 126 patients were registered prospectively at a university hospital in Sweden, 63 patients who underwent simultaneous resection were matched against 63 patients who underwent staged resection.Results: The length of hospital stay was shorter for the simultaneous resection group, at 11 vs 16 days, p = <0.001. Fewer patients experienced recurrence in the simultaneous resection group 39 vs 50 pa-tients, p = 0.012. There were no significant differences in disease-free survival and overall survival be-tween the groups. Age (hazard ratio [HR] 1.72; 95% CI 1.01-2.94; p = 0.049) and Clavien-Dindo score (HR 2.22; 95% CI 1.06-4.67; p = 0.035) had impact on survival. Conclusion: Colorectal cancer with synchronous liver metastases can be resected simultaneously, and enables a shorter treatment time without jeopardizing oncological outcomes.

Intraductal papillary neoplasms of the bile ducts : a comparative study of a rare disease in Europe and Nagoya, Japan
- 2024
-
In: HPB. - : ELSEVIER SCI LTD. - 1365-182X .- 1477-2574. ; 26:4, s. 565-575

Journal article (peer-reviewed)abstract
- Background: Intraductal papillary neoplasm of the bile ducts (IPNB) is a rare disease in Western countries. The aim of this study was to compare tumor characteristics, management strategies, and outcomes between Western and Eastern patients who underwent surgical resection for IPNB. Methods: A multi-institutional retrospective series of patients with IPNB undergoing surgery between January 2010 and December 2020 was gathered under the auspices of the European-African Hepato-Pancreato-Biliary Association (E-AHPBA), and at Nagoya University Hospital, Japan. Results: A total of 85 patients (51% male; median age 66 years) from 28 E-AHPBA centers were compared to 91 patients (64% male; median age 71 years) from Nagoya. Patients in Europe had more multiple lesions (23% vs 2%, P < .001), less invasive carcinoma (42% vs 85%, P < .001), and more intrahepatic tumors (52% vs 24%, P < .001) than in Nagoya. Patients in Europe experienced less 90-day grade >3 Clavien-Dindo complications (33% vs 68%, P < .001), but higher 90-day mortality rate (7.0% vs 0%, P = .03). R0 resections (81% vs 82%) were similar. Overall survival, excluding 90-day postoperative deaths, was similar in both regions. Discussion: Despite performing more extensive resections, the low perioperative mortality rate observed in Nagoya was probably influenced by a combination of patient-, tumor-, and surgery-related factors.
