Background:
The isolated bile duct is sometimes observed in the right liver graft of living donor liver transplantation (LDLT). Even though, as a rescue option, it is known to use the recipient's cystic duct (CyD) for duct-to-duct anastomosis, the long-term feasibility of rescue duct-to-CyD (D-CyD) anastomosis remains unclear.
Methods:
We prospectively collected data in the right liver-LDLT cohort and compared rescue D-CyD anastomosis (n = 4) with standard duct-to-hepatic duct (D-HD, n = 45) anastomosis (D-CyD group, n = 4).
Results:
The observation period was over 5 years (range, 68-171 mo) after LDLT. The D-CyD group included the following anastomosis procedures: anastomosis between the intrahepatic bile duct of the graft and the CyD of the recipient and anastomosis between the posterior HD and the CyD. Surgical outcomes between the 2 groups are similar, excluding the time for the biliary reconstruction (D-CyD, 116 ± 13 min vs D-HD, 57 ± 3 min). During the period, one recipient in the D-CyD group exhibited postoperative biliary stricture and biliary stone, and 6 recipients underwent those complications in the D-HD group (D-CyD, 25.0% vs D-HD, 13.3%) All recipients in the D-CyD group are presently alive and have not experienced liver dysfunction.
Conclusions:
Our findings suggest that rescue D-CyD anastomosis for an isolated bile duct in a right liver LDLT is acceptable as a life-saving option in terms of long-term feasibility.
