    Abstract:
    Right lobe (RL) living donor liver transplantation (LDLT) usually includes 2 bile duct anastomosis sites, namely, the right anterior and the right posterior segmental ducts. This study aimed to evaluate the optimal treatment for biliary strictures following RL LDLT with respect to unilateral or bilateral drainage techniques. From January 2005 to December 2017, 883 patients at Seoul National University Hospital underwent RL LDLT. Of these, 110 patients were enrolled who had 2 duct-to-duct anastomosis sites and who were considered at risk of developing biliary anastomotic strictures. Unilateral or bilateral biliary drainage during the follow-up period was identified by endoscopic retrograde cholangiopancreatography (ERCP) and/or percutaneous transhepatic biliary drainage (PTBD). The clinical success, complication, and 180-day mortality rates were compared between the unilateral and bilateral biliary drainage groups according to the initial ERCP findings. The mean age at the time of LDLT was 54.2 ± 8.2 years. The median time from LDLT to initial biliary anastomotic strictures was 177 (interquartile range, 18-1085) days. At the initial ERCP, unilateral drainage was performed in 55 (50.0%) patients, and bilateral drainage was performed in 11 (10.0%) patients. Of the patients who underwent unilateral drainage, 35 (63.6%) patients required conversion to bilateral drainage during follow-up. Overall, 71 (64.5%) patients required bilateral drainage more than once, whereas only 27 (24.5%) patients reached a resolution with unilateral biliary drainage. In this study, most patients required bilateral biliary drainage more than once during follow-up. An active attempt should be made to drain bilaterally in patients with biliary anastomotic strictures following RL LDLT.
