ABSTRACT
Biliary complications (BCs) following living donor liver transplantation (LDLT) can lead to significant morbidity and occasional mortality. The present study describes our experience of the all-knots-outside technique (AKOT) of biliary reconstruction (BR) and its impact on BCs. A retrospective analysis was performed using prospectively collected data of 330 consecutive adult patients undergoing LDLT from July 2011 to February 2018 with a minimal follow-up of 24 months. Only 2.8% required hepaticojejunostomy and were excluded. In an initial 122 patients, BR was performed with the standard technique (ST), and AKOT was performed in the subsequent 208 patients. In the AKOT group, a single anastomosis was attempted even for multiple ducts whenever feasible. A major BC was defined as requiring endoscopic, percutaneous, or surgical interventions. In the AKOT group, significantly more patients received a left lobe graft (5.7% versus 18.3%; P = 0.001), had shorter warm ischemia time (44.6 versus 27 minutes; P < 0.001), and had a left hepatic artery (LHA) in the right lobe that was used for arterial reconstruction (48 [39.3%] versus 122 [58.6%]; P = 0.003). The incidence of BCs in the entire cohort was 47 (14.2%). For the ST versus AKOT groups, the overall BCs (27/122 [22.1%] versus 20/208 [9.6%]; P = 0.003) and major BCs (20.5% versus 6.7%; P < 0.001) decreased significantly. In the multivariate analysis, the number of bile ducts (hazard ratio [HR], 4.18; 95% confidence interval [CI], 1.62-10.78; P = 0.003), number of anastomoses (HR, 2.03; 95% CI, 1.03-4.02; P = 0.04), and technique of anastomosis (HR, 0.36; 95% CI, 0.19-0.68; P = 0.002) predicted BCs. In conclusion, in adult LDLT, with standardization of the donor and recipient surgery, preferential use of LHA for right lobe arterial reconstruction, reduction in the number of anastomoses, and AKOT for BR significantly decreased the incidence of BCs.
