    BackgroundAn anastomotic biliary stricture is a complication of living donor liver transplantation (LDLT) performed using duct-to-duct anastomosis. Despite advances in treating this complication, there is no one established treatment protocol.ObjectiveTo investigate the safety, effectiveness, and mid-term outcome of magnetic compression anastomosis (MCA) for treating biliary obstruction after LDLT when the obstruction cannot be resolved by using percutaneous or peroral methods.DesignRetrospective, observational study with standardized treatment and follow-up.SettingTertiary-care academic medical center.PatientsTwelve patients underwent MCA procedures to treat anastomosis site stricture after LDLT.InterventionsMCA.Main Outcome MeasurementsBile duct patency, technique performance, and complications were evaluated.ResultsWe achieved magnet approximation at the anastomotic stricture in 10 of 12 patients (83.3%). The magnets failed to approximate in 2 patients. We achieved recanalization of the stricture site in 10 of 10 patients. We removed an internal catheter in 9 patients. The mean interval from magnet approximation to removal was 74.2 days (range 14-181 days). The mean time from recanalization to removal of the internal catheter was 183 days (range 51-266 days). Patients were examined regularly after removing the internal catheter with a mean follow-up period of 331 days (range 148-581 days). The observed MCA-related complications consisted of 1 case of mild cholangitis and 1 recurrence of the anastomotic stricture.LimitationsNonrandomized study design.ConclusionsMCA safely and effectively resolved post-LDLT biliary duct-to-duct anastomotic strictures that could not be resolved using conventional methods, such as ERCP and percutaneous transhepatic biliary drainage.Copyright © 2011 American Society for Gastrointestinal Endoscopy.
