    Abstract:
    The outcome after living donor liver transplantation (LDLT) using grafts with multiple bile ducts (BDs) remains unclear. We analyzed 510 patients who received an adult-to-adult right lobe LDLT between 2000 and 2015 and compared outcome parameters of those receiving grafts with 2 BDs (n = 169) with patients receiving grafts with 1 BD (n = 320). Additionally, patients receiving a graft with 3 BDs (n = 21) were analyzed. Demographic variables and disease severity were similar between the groups. Roux-en-Y reconstruction was significantly more common in the 2 BD group (77% versus 38%; P < 0.001) compared with the 1 BD group. No difference was found in biliary complication rates within 1 year after LDLT (1 BD versus 2 BD groups, 18% versus 21%, respectively; P = 0.46). In the 2 BD group, 82/169 (48.5%) patients were reconstructed with 2 anastomoses. The number of anastomoses did not negatively impact biliary complication rates. Recipients' major complication rate (Clavien ≥ 3b) was similar between both groups (1 BD versus 2 BD groups, 21% versus 24%, respectively; P = 0.36). Furthermore, no difference could be found between the 1 BD, the 2 BD, and the 3 BD groups in the frequency of developing biliary complications within 1 year (18%, 21%, 14%, respectively; P = 0.64), BD strictures (15%, 15%, 5%, respectively; P = 0.42), or BD leaks (10%, 11%, 10%, respectively; P = 0.98). In addition, the 1-year (90% versus 91%), 5-year (82% versus 77%), and 10-year (70% versus 66%) graft survival rates as well as the 1-year (92% versus 93%), 5-year (84% versus 80%), and 10-year (75% versus 76%) patient survival rates were comparable between the 1 BD and the 2 BD groups (P = 0.41 and P = 0.54, respectively). In conclusion, this study demonstrates that selected living donor grafts with 2 BDs can be used safely without negatively impacting biliary complication rates and graft or patient survival rates.
