| Popis: | Introduction Anastomotic biliary strictures (ABS) have been reported in approximately 13% of patients undergoing orthotopic liver transplantation (OLT). Without treatment these can lead to progressive graft failure. Endoscopic management of these strictures with temporary fully covered self-expanding metal stents (SEMS) offers a non-surgical option for their management. This retrospective case series describes the outcomes of ABS managed using SEMS at our centre. Unit standard practice is to reserve endoscopic management for early ABS and undertake a biliary sphincterotomy to reduce pancreatitis risk. Methods The electronic records of all patients who underwent both OLT and endoscopic retrograde cholangiopancreatography (ERCP) between January 2013 and March 2020 were reviewed. Patients were selected from this group if they were found to have an ABS as diagnosed by biochemical liver function test derangement and corresponding characteristic radiological findings. Demographic data, technical aspects of the procedure, success rate, and complications were recorded. Results A total of 36 transplant recipients were diagnosed with ABS. This group underwent a total of 45 ERCP procedures. The median time from transplant to ABS diagnosis was 6 months (interquartile range (IQR) 2 – 22 months). There was a balloon dilatation prior to stent placement in 13 procedures (29%). There was a sphincterotomy either at the time of stent placement or during a preceding procedure in 33 cases (92%). There were ten cases of pancreatitis (22%), four cases of cholangitis (9%) and two of bile leak (4%). There were eight cases of pancreatitis in the group of 33 who had undergone sphincterotomy (24%) and two cases of pancreatitis in the group of three who had not (67%). There was one case of bleeding following sphincterotomy (3%) that occurred immediately and did not require transfusion. The median time to stent removal was 105 days (IQR 67 – 125). Only one case (3%) required surgical biliary reconstruction. The avoidance of the need for biliary reconstruction was regarded as the key outcome for successful endoscopic management of ABS and this was achieved in 35 cases (97%). Conclusion Early ABS following OLT were effectively managed using endoscopically placed biliary stents in the majority of cases. The rate of pancreatitis was lower in the sphincterotomy group. These data support the practice of temporary SEMS placement for early ABS and sphincterotomy to reduce pancreatitis risk. |
