Abstract
BACKGROUND: Biliary complication is one of the major donor complications during and after hepatectomy in living donor liver transplantation (LDLT). We evaluated risk factors for donor biliary complication in adult-to-adult LDLT. PATIENTS AND METHODS: From March 2002 to November 2016, 126 consecutive patients who underwent donor hepatectomy in adult-to-adult LDLT were divided into 2 groups according to biliary compilations: nonbiliary complication (non-BC) group (n = 114) and biliary complication (BC) group (n = 12). RESULTS: Among 126 donor hepatectomies, 35 patients (28%) experienced perioperative complications, including 10 (7.9%) with Clavien-Dindo classification grade III. Biliary complications occurred in 12 patients (9.5%): bile leakage in 10 and intraoperative bile duct injury in 2. Additional computed tomography- and/or ultrasound-guided drainage or exchange of original drain was required in 7 patients. In comparison between BC and non-BC groups, future remnant liver volume was significantly higher in the BC group than in the non-BC group (63% vs 40%; P = .02). In multivariate analysis, larger future remnant liver volume (P = .005) and shorter operating time (P = .02) were identified as independent risk factors for biliary complications. We had 2 patients with intraoperative bile duct injury: both were successfully treated by duct-to-duct biliary anastomosis with insertion of biliary stent or T-tube. CONCLUSION: Large remnant liver volume was a significant risk factor for biliary complications, especially biliary leakage, after donor hepatectomy. For intraoperative bile duct injury, duct-to-duct anastomosis with biliary stent is a feasible method to recover.
