Evaluating the accuracy of three international guidelines in identifying the risk of malignancy in pancreatic cysts: a retrospective analysis of a surgical treated population.

BACKGROUND AND STUDY AIMS: The international consensus Fukuoka guideline (Fukuoka ICG), The European evidence-based guideline on pancreatic cystic neoplasms (European EBG) and the American Gastroenterological Association institute guideline on the diagnosis and management of asymptomatic neoplastic pancreatic cysts (AGA IG) are 3 frequently cited guidelines for the risk stratification of neoplastic pancreatic cysts. The aim of this study was to assess the accuracy of detecting malignant cysts by strictly applying these guidelines retrospectively to a cohort of surgically resected pancreatic cysts. PATIENTS AND METHODS: 72 resected cysts were included in the analysis. Invasive carcinoma, high grade dysplasia and neuro-endocrine tumour were considered as "malignant cysts" for the purpose of the study. RESULTS: 32% of the resected cysts were malignant. The analysis showed that the Fukuoka ICG, European EBG and AGA IG had a sensitivity of 66,8%, 95,5%, 80%; a specificity of 26,8%, 11,3%, 43,8%; a positive predictive value of 31,8%, 35%, 47,1% and a negative predicted value of 61,1%, 83,3%, 77,8% respectively. The missed malignancy rate was respectively 11,3%, 1,5%, 7,7% and surgical overtreatment was respectively 48,4%, 59,1%, 34,6%. CONCLUSION: In this retrospective analysis, the European EBG had the lowest rate of missed malignancy at the expense of a high number of "unnecessary" resections. The Fukuoka ICG had the highest number of missed malignancy. The AGA IG showed the lowest rate of unnecessary surgery at the cost of a high number of missed malignancy. There is need to develop better biomarkers to predict the risk of malignancy.

Treatment of recurrent severe hepatic encephalopathy in patients with large porto-collaterals shunts or transjugular portosystemic shunt.

Patients with hepatic encephalopathy (HE) do not systematically receive priority on the waiting list for liver transplantation. In some patients with cirrhosis, excessive amounts of gut derived ammonia can bypass the liver parenchyma due to large spontaneous portosystemic shunts (SPSS) induced by portal hypertension. A similar but iatrogenic condition can occur after transjugular portosystemic shunt (TIPS) insertion. In these situations HE may develop and can become refractory to standard management. In patients with preserved liver function, embolization of large SPSS has been shown to control HE mostly without aggravation of other portal hypertensive complications. In case of post-TIPS HE endovascular shunt reduction is able to control refractory post-TIPS HE in the majority of the patients. New strategies to prevent post-TIPS, such as the use of controlled expansion endoprosthesis, are currently explored.

Improved survival after LTx-associated acute GVHD with mAb therapy targeting IL2RAb and soluble TNFAb: Single-center experience and systematic review.

Acute graft-versus-host disease (GVHD) after liver transplant (LTx) is a rare complication with a high mortality rate. Recently, monoclonal antibody (mAb) treatment, specifically with anti-interleukin 2 receptor antibodies (IL2RAb) and anti-tumor necrosis factor-α antibodies (TNFAb), has gained increasing interest. However, evidence is mostly limited to case reports and the efficacy remains unclear. Here, we describe 5 patients with LTx-associated GVHD from our center and provide the results of our systematic literature review to evaluate the potential therapeutic benefit of IL2RAb/TNFAb treatment. Of the combined population of 155 patients (5 in our center and 150 through systematic search), 24 were given mAb (15.5%)-4 with TNFAb (2.6%) and 17 with IL2RAb (11%) ("mAb group")-and compared with patients who received other treatments (referred to as "no-mAb group"). Two-sided Fisher exact tests revealed a better survival when comparing treatment with mAb versus no-mAb (11/24 vs 27/131; P = .018), TNFAb versus no-mAb (3/4 vs 27/131; P = .034), and IL2RAb versus no-mAb (8/17 vs 27/131; P = .029). This systematic review suggests a beneficial effect of mAb treatment and a promising role for TNFAb and IL2RAb as a first-line strategy to treat LTx-associated acute GVHD.

Achieving WHO recommendations for Hepatitis C Virus Elimination in Belgium.

BACKGROUD: The World Health Organization (WHO) released updated guidelines for the screening, care and treatment of patients with chronic hepatitis C virus (HCV) infection. METHODS: A previously described HCV disease burden model was used to develop a "WHO scenario" to achieve the WHO recommendations of a 90% reduction in incidence and 65% reduction in liver-related deaths. After determining the steps necessary to achieve this goal, the impact of realistic constraints was modeled. RESULTS: In 2015, there were 66.200 viremic infections, with 43% diagnosed and 1.350 treated. In order to reduce new infections, treatment must be extended to ≥ F0 patients, including people who inject drugs and other individuals at risk of transmitting HCV. -Additionally, diagnosis and treatment of 3.030 and 4.060 patients, respectively, would be required. The largest attenuation of the WHO scenario would occur if no new cases were diagnosed after 2018 (300% more viremic infections by 2030). Limiting treatment to ≥ F2 patients or treating fewer patients (3.000) would result in 220% or 140% more viremic cases, respectively, compared with the WHO scenario. CONCLUSION: Achieving the WHO guidelines in Belgium requires a coordinated effort to scale up treatment and prevention efforts and to allow treatment access to patients of all fibrosis stages. A scale-up of treatment, however, requires patients to be both diagnosed and linked to care, suggesting a need for increased awareness and expanded screening efforts. Finally, prevention of new HCV infections requires a comprehensive understanding of the population at risk of transmitting HCV.

Patients with large-duct primary sclerosing cholangitis and Crohn's disease have a better outcome than those with ulcerative colitis, or without IBD.

BACKGROUND: Approximately 20% of primary sclerosing cholangitis (PSC) patients with concomitant inflammatory bowel disease (IBD) have Crohn's disease (CD). AIM: To compare PSC/CD with other PSC patients. METHODS: Retrospective study of 240 PSC patients diagnosed between 1975 and 2012 (median follow-up 12 years). Activity of PSC at diagnosis was assessed by liver biopsy, Mayo risk and ERC scores. Survival without liver transplantation, number of transplantations and liver-related death were endpoints. RESULTS: Sixty-three per cent of patients had IBD: 105 UC, 32 CD and 14 IBD unclassified (IBDu). IBD was diagnosed before PSC in 50%. The yearly development of PSC after diagnosing IBD was similar in UC, CD or IBDu. Small-duct PSC was present in 28% of PSC/CD compared to 3% of PSC/UC. Small-duct PSC had a markedly better survival than large-duct PSC: no patient developed cholangiocarcinoma or liver-related death, but colorectal cancer occurred in three patients. In large-duct PSC, a more favourable outcome was evident in patients with CD. The liver disease was less progressive: one patient underwent liver transplantation compared to 28% and liver-related deaths were absent compared to 7% in the other PSC groups. CONCLUSIONS: The prevalence of PSC with concomitant Crohn's disease is relatively rare, but the outcome is more benign than PSC with UC or without IBD. Approximately one-fourth has small-duct PSC. In large-duct PSC/CD, liver disease is less aggressive and the outcome is much better. The outcome of PSC patients with UC resembled that of PSC without IBD.

Belgian experience with triple therapy with boceprevir and telaprevir in genotype 1 infected patients who inject drugs.

No data have been reported yet on treatment outcome in persons who inject drugs (PWID) infected with hepatitis C virus treated with boceprevir or telaprevir in combination with peginterferon (Peg IFN) and ribavirin (RBV). Additionally, there are concerns about the safety of boceprevir and telaprevir in some subgroups of patients with hepatitis C (HCV). In a cohort of HCV patients infected with genotype 1 in Belgium, treatment outcome of patients infected due to IV drug use was analyzed and compared with patients who have no history of substance use. The study population consisted of 179 patients: 78 PWID and 101 controls treated with boceprevir (n = 79) or telaprevir (n = 100) additional to Peg IFN and RBV; 53 (30%) had advanced disease (F3, F4) and 79 (44%) had an antiviral therapy previously. There were no significant differences in the baseline characteristics between both groups, except that PWID patients were more frequently infected with genotype 1a (67% vs 21%), were younger and were predominantly male. Psychiatric complaints during follow-up occurred more frequently in the PWID patients: 24% versus 11% (P = .02). Treatment failure for other reasons than absence of viral response was 70% and 64% in PWID and non-PWID respectively. The sustained viral response (SVR) rates were similar in both groups (71% in PWID vs 72% in non-PWID); with a non-inferiority test with -5% margin there is a difference of -1% (95% CI [-15%, 13%]) and P = 0.30. There are no reasons to exclude PWID from treatment with boceprevir, telaprevir and novel antiviral therapies.

Budd-Chiari syndrome: reassessment of a step-wise treatment strategy.

BACKGROUND AND STUDY AIMS: The Budd-Chiari syndrome is a rare disorder characterized by hepatic venous outflow obstruction. A step-wise management was recently proposed. The aim of this study is to reassess our treatment approach and long-term outcome. PATIENTS AND METHODS: The data of 37 Budd-Chiari patients, seen in our unit, were critically analyzed and compared with the ENVIE (European Network For Vascular Disorders of the Liver) data. RESULTS: Most patients had multiple prothrombotic conditions (41%), of which an underlying myeloproliferative neoplasm was the most frequent (59%). The JAK2V617F mutation was associated with more complete occlusion of all hepatic veins (JAK2 mutation +: 70% vs JAK2 mutation -: 23% and a higher severity score. The step-wise treatment algorithm used in our unit, in function of the severity of the liver impairment and the number and the extension of hepatic veins occluded, resulted in the following treatments: only anticoagulation (n = 7.21%), recanalization procedure (n = 4.21%), portosystemic shunts (n = 9.26%) and liver transplantation (n = 14.44%). This resulted in a 10 year survival rate of 90%. Treatment of the underlying hemostatic disorder offered a low recurrence rate. None of the 21 patients with a myeloproliferative neoplasm died in relation to the hematologic disorder. CONCLUSIONS: An individualized treatment regimen consisting of anticoagulation and interventional radiology and/or transplantation when necessary and strict follow-up of the underlying hematologic disorder, provided an excellent long-term survival, which confirm the data of the ENVIE study.

The Disease Burden of Hepatitis C in Belgium : An update of a realistic disease control strategy.

BACKGROUND: This manuscript serves as an update to position papers published in 2014 based on the available Belgian hepatitis C virus (HCV) epidemiological data. METHODS: Building on the current standard of care (2015 : 900 ≥ F3 patients treated with 70-85% SVR), four new scenarios were developed to achieve the goals of near viral elimination and prevention of HCV associated morbidity and mortality by 2026 and 2031. Increases in treatment efficacy were assumed in 2016 (90% SVR) and 2017 (95% SVR). RESULTS: Scenario 1: Treating 6,670 patients annually by 2018 (≥ F0 beginning in 2017) and diagnosing 3,790 patients annually by 2020, a 90% reduction in viremic cases and advanced outcomes was observed by 2026. Scenario 2: Treating 4,300 patients annually by 2018 (≥ F0 beginning in 2020) without increasing the number diagnosed, a 90% reduction in viremic cases and 85%-95% reduction in advanced outcomes was observed by 2031. Scenario 3: Treating 5,000 ≥ F2 patients annually by 2018, and diagnosing 3,620 patients annually by 2020, a 90% reduction in advanced outcomes and 50% reduction in viremic cases was observed by 2026. Scenario 4: Treating 3,100 ≥ F2 patients annually by 2018 without increasing the number diagnosed, a 90%-95% reduction in advanced outcomes and 55% reduction in viremic cases was observed by 2031. CONCLUSIONS: Scenario 2 would provide the most favorable balance of outcomes (90% reduction in viremic prevalence and advanced outcomes) and realistic requirements for implementation (gradual increase in treatment, delayed incorporation of patients with no/mild fibrosis).

Preoperative arterial embolization facilitates multivisceral transplantation for portomesenteric thrombosis.

Multivisceral transplantation (MvTx) for diffuse venous portomesenteric thrombosis is a surgically and anesthesiologically challenging procedure, partly because of the risk of massive bleeding during visceral exenteration. Preoperative visceral artery embolization might reduce this risk. In three consecutive MvTx, the celiac trunk (CT) and superior mesenteric artery (SMA) were embolized immediately pretransplant. We analyzed demographics, serum D-lactate, pH, base excess, hemoglobin, blood pressure, transfused packed cell (PC) units, intervention time and outcome. Results are reported as median (range). All recipients were male (43, 22, 47 years old). Portomesenteric thrombosis followed antiphospholipid syndrome, neuroendocrine tumor and liver cirrhosis. A peritransplant D-lactate peak of 6.1 (5.1-7.6) mmol/L, lowest pH of 7.24 (7.18-7.36) and lowest base excess level of -9.5 (-7.6 to -11.5) were observed. Values normalized within 3 h posttransplant. Embolization and exenteration times were 80 (70-90) min and 140 (130-165) min, respectively, during which blood pressure remained stable, lowest hemoglobin was 6.1 (6.1-7.6) g/dL and three (2-4) PC were administered. All procedures were uneventful. Follow-up was 7 (4-9) months. The first patient died 4 months post-MvTx after an intracranial bleeding; the other patients are doing well. Our experience suggests that preoperative embolization of CT and SMA facilitates native organ resection in MvTx.

The disease burden of hepatitis C in Belgium: development of a realistic disease control strategy.

BACKGROUND: Novel direct antiviral agents (DAAs) will become available soon with higher sustained viral response (SVR), fewer side-effects and higher compliance. Our aim was to evaluate different realistic strategies to control the projected increase in HCV-related disease burden in Belgium. METHODS: Based on literature review, expert opinions and historical assumptions, HCV-disease progression and mortality in Belgium was modeled to 2030. Strategies exploring the impact of increased treatment, treatment delay, and treatment restrictions were developed. RESULTS: Although the overall HCV prevalence is decreasing in Belgium, the burden of advanced stage HCV, including cirrhosis and hepatocellular carcinoma (HCC), is expected to increase under current treatment and cure rates. By increasing SVR to 90% from 2016 onward and the number of treated cases (from 710 to 2,050), in 2030 the cases with cirrhosis, decompensated cirrhosis and HCC would be significantly lower than in 2013. This strategy was found most efficient when applied to F2-F4 cases. To obtain comparable outcomes with F0-F4 cases, 3,490 patients should be treated. A two year delayed access to the DAAs increased HCV related morbidity and mortality by 15% relative to our strategy. CONCLUSIONS: Considering the evolving burden of HCV disease and the need for efficacious usage of healthcare resources, primary application of new DAAs in Belgium should focus on patients with significant and advanced fibrosis (F2-F4), providing these new drugs without delay upon availability and increasing access to therapy.

Hepatitis C epidemiology in Belgium.

BACKGROUND: The burden of hepatitis C virus (HCV) infection is significant and is increasing with the aging population. The results of a modeling study that included Belgium, along with many other countries, was published in April 2014. An in depth discussion surrounding the epidemiology of HCV in Belgium will be presented here. METHODS: A systematic literature review was conducted to assess the historical and current clinical burden of HCV in Belgium. Two expert panels were convened to discuss the strengths and limitations surrounding the available data and to generate consensus regarding the best estimates for total number of HCV cases, number of cases diagnosed, and the number of patients treated and cured, including potential HCV control strategies. RESULTS: Although no national studies exist, there were an estimated 70,000 (10,000-91,000) viremic HCV infections in 1994. By 2010 there were an estimated 22,900 individuals diagnosed with viremic HCV, and in 2011 approximately 710 patients were treated annually. An estimated 13% of liver transplants were attributable to HCV in 2011. Genotype 1 predominated (59%), followed by genotypes 3 (19%) and 4 (14%). CONCLUSIONS: Estimates of HCV prevalence, diagnosed cases and liver transplants due to HCV were available through published studies. However these publications were subject to bias and were occasionally outdated. Improved estimates of HCV prevalence would be useful for informing treatment, prevention and policy efforts in Belgium.

Current and future health and economic impact of hepatitis C in Belgium.

BACKGROUND AND STUDY AIMS: Chronic hepatitis C virus (HCV) infection is a serious global health problem affecting 150 million individuals worldwide. Although infection rates are decreasing, an aging population with progressing disease is expected to result in increased burden of advanced stage disease with high associated costs. This analysis describes the current and projected future economic impact of HCV sequelae in Belgium. METHODS: A previously described and validated model was populated with Belgian inputs and calibrated to project the current and future health and economic burden of HCV. Monte Carlo and sensitivity analyses were run to quantify uncertainty. All estimates exclude the cost of antiviral therapy. RESULTS: Costs associated with HCV were projected to peak in 2026 at Euro126M (Euro30M-Euro257M), while decompensated cirrhosis and hepatocellular carcinoma costs were projected to increase until 2031 and 2034. The projected 2014-2030 cumulative cost of HCV under current conditions was Euro1,850M. Scenarios to reduce the burden of HCV could result in Euro70M-Euro400M in cumulative cost savings. Starting treatment (1,000 patients) in 2015 could result in Euro150M cost savings. The lifetime cost of HCV increases with life expectancy, with highest future costs projected among young females with early stage disease. CONCLUSIONS: The economic burden of HCV and advanced stage disease were projected to further increase. Cost reductions are possible with timely interventions aimed at minimizing the health burden of advanced stage disease.

Combined liver and lung transplantation with extended normothermic lung preservation in a patient with end-stage emphysema complicated by drug-induced acute liver failure.

Isolated lung transplantation (LuTx) and liver transplantation are established treatments for irreversible lung and liver failure. Combined liver and lung transplantation (cLiLuTx) is a less common, but approved therapy of combined organ failure, mostly applied in patients suffering from progressive cystic fibrosis and advanced liver disease. We report a patient who was listed for LuTx due to end-stage chronic obstructive pulmonary disease and who developed drug-induced acute hepatic failure. The only therapeutic option was hyper-urgent cLiLuTx. To correct the poor coagulation in order to reduce the per-operative risk of bleeding, the liver was transplanted first. In anticipation of the longer lung preservation time, cold flushed lungs were preserved on a portable lung perfusion device for ex vivo normothermic perfusion for 11 h 15 min, transplanted sequentially off-pump, and reperfused after a total ex vivo time of 13 h 32 min and 16 h for the first and second lung, respectively. Ten months later, the patient is doing well and no rejection occurred. Normothermic ex vivo lung perfusion may help to prolong preservation time, facilitating long-distance transport and combined organ transplantation.

Ectopic liver tissue in two distinct anatomical regions: a case report.

Extrahepatic liver tissue (ELT) is a rare clinical finding. Few cases are described. The reported location is almost exclusively confined to the subdiaphragmatic region with the gallbladder being the most frequent localisation. This paper describes a unique case with not only two localisations of ectopic liver tissue, but also in anatomical regions where ELT has never been described before.

Spontaneous life-threatening hemobilia during acute liver failure successfully treated with transarterial embolization.

A 28-year-old patient admitted with jaundice, vomiting and deteriorating coagulopathy was diagnosed with acute liver failure. After listing for urgent transplantation, he developed Boerhaave's syndrome and massive hemobilia, two life-threatening complications. Massive hemobilia secondary to a fistula between the right hepatic artery and the right bile duct occurred several days after transjugular biopsy and was controlled with fluid resuscitation, transfusion and arterial embolization. Two days later he was transplanted successfully, and is currently doing well after more than 72 months. Aggressive treatment of potentially reversible complications during acute liver failure whilst awaiting transplantation is mandatory to allow survival of these patients.

Risk factors for bleeding and clinical implications in patients undergoing liver transplantation.

INTRODUCTION: Advanced liver disease is characterized by prolonged global coagulation tests such as prothrombin time (PT). Using Model of End-stage Liver Disease (MELD) score-based allocation, many current transplant recipients show advanced end-stage liver disease with an elevated international normalized ratio (INR). The relationship between abnormalities in coagulation tests and the risk of bleeding has been recently challenged among liver disease patients. In this study we reassessed risk factors for bleeding and the clinical implications for patients who underwent orthotopic liver transplantation (OLT). METHODS: We studied OLT patients between 2005 and 2011 excluding combined transplantations, retransplantations, or cases due to acute liver failure. We collected prospectively pre-OLT, during OLT, and post-OLT clinical and biochemical data to assess the risk for bleeding using linear regression models. RESULTS: The strongest predictor of overall survival among 286 patients with a mean follow-up of 32 months was the number of blood transfusions (P = .005). The risk factor for bleeding during surgery investigated by multivariate analysis only showed the INR (P < .001) and the presence of ascites (P = .003) to independently correlate with the amount of blood transfusion. Receiver operation characteristics (ROC) analysis performed to determine the risk for massive blood transfusion (more than 6 units) revealed a cut-off value for INR ≥ 1.6. Appreciation of the operative field by the surgeon during the intervention as "wet" versus "dry", amounts of blood transfusion and fresh frozen plasma, and stay in the intensive care unit (ICU) and in the hospital were all significantly different (P < .001) for patients with INR <1.6 versus INR ≥ 1.6. CONCLUSIONS: Bleeding during OLT affects the outcome. The risk is independently influenced by the presence of ascites (probably reflecting the degree portal hypertension) and an INR ≥ 1.6. To improve survival after OLT therapeutic interventions should be further explored to reduce the need for blood transfusions.

Septuagenarian and octogenarian donors provide excellent liver grafts for transplantation.

BACKGROUND: Wider utilization of liver grafts from donors ≥ 70 years old could substantially expand the organ pool, but their use remains limited by fear of poorer outcomes. We examined the results at our center of liver transplantation (OLT) using livers from donors ≥ 70 years old. METHODS: From February 2003 to August 2010, we performed 450 OLT including 58 (13%) using donors ≥ 70 whose outcomes were compared with those using donors <70 years old. RESULTS: Cerebrovascular causes of death predominated among donors ≥ 70 (85% vs 47% in donors <70; P < .001). In contrast, traumatic causes of death predominated among donors <70 (36% vs 14% in donors ≥ 70; P = .002). Unlike grafts from donors <70 years old, grafts from older individuals had no additional risk factors (steatosis, high sodium, or hemodynamic instability). Both groups were comparable for cold and warm ischemia times. No difference was noted in posttransplant peak transaminases, incidence of primary nonfunction, hepatic artery thrombosis, biliary strictures, or retransplantation rates between groups. The 1- and 5-year patient survivals were 88% and 82% in recipients of livers <70 versus 90% and 84% in those from ≥ 70 years old (P = .705). Recipients of older grafts, who were 6 years older than recipients of younger grafts (P < .001), tended to have a lower laboratory Model for End-Stage Liver Disease score (P = .074). CONCLUSIONS: Short and mid-term survival following OLT using donors ≥ 70 yo can be excellent provided that there is adequate donor and recipient selection. Septuagenarians and octogenarians with cerebrovascular ischemic and bleeding accidents represent a large pool of potential donors whose wider use could substantially reduce mortality on the OLT waiting list.

Outcomes of liver transplantations using donations after circulatory death: a single-center experience.

INTRODUCTION: Orthotopic liver transplantation (OLT) (LTx) using donation after circulatory death (DCD) donors is increasingly performed, but still considered to risk of poorer outcomes compared with standard donations after brain death (DBD)-OLT. Therefore we reviewed our results of DCD-OLT. PATIENTS AND METHODS: Between 2003 and 2010, we performed 30 DCD-OLT (6% of all OLT). We retrospectively reviewed medical records of donors and recipients after DCD versus DBD-OLT to analyze biliary complications, retransplantation rates, and patient/graft survivals. RESULTS: Median donor age was similar for DCD and DBD-OLT: 51 versus 53 years (P = .244). Median donor warm ischemia time (stop ventilation to cold perfusion in DCD donors) was 24 minutes. Median cold ischemia time was shorter for DCD (6 hours 54 minutes) compared with DBD-OLT (8 hours 36 minutes; P < .0001). Median laboratory model of end-stage liver disease score was 15 for DCD, and 16 for DBD-OLT (P = .59). Median post-OLT Aspartate Aminotransferase (AST) peak was higher after DCD: 1178 versus DBD-OLT 651 IU/L (P = .005). The incidence of nonanastomotic strictures was different: 33.3% for DCD versus 12.5% for DBD-OLT (P = .001). The overall retransplantation rate was 3% after both DCD and DBD-OLT. After DCD-LTx actuarial 1, 3- and 5-year patient survivals were 93, 85 and 85%, and corresponding graft survivals, 90%, 82%, and 82% respectively, and not different compared with DBD-OLT: 88%, 78%, and 72% (P = .348) and 85%, 74%, and 68% (P = .524) respectively. CONCLUSION: Despite substantial ischemic injury (high peak AST and biliary strictures) short- and long-term survival after DCD-OLT was comparable to DBD-OLT. Rapid donor surgery, careful donor and recipient selection, as well as short warm and cold ischemia times are key factors to optimize outcomes after DCD-OLT. However, strategies to reduce biliary complications remain warranted.

An unusual case of rectal perforation after liver transplantation.

We present the case of a 50-year-old patient in whom an anastomotic biliary stricture after liver transplantation was treated endoscopically by sphincterotomy, dilatation and stenting using a plastic biliary stent. A distal migration of the stent caused a perforation of the rectum which was treated following stent extraction per anum -- conservatively with antibiotics and temporary bowel rest.
