In situ dye injection bile leakage test of the graft in living donor liver transplantation

Bile leakage after living donor liver transplantation (LDLT) remains a serious problem, resulting in lower survival rates. The aim of this study is to clarify the benefits of in situ leakage testing of the cut surface of grafts in LDLT. A total of 135 LDLTs were analyzed. The patients were divided into the following two groups according to the in situ dye injection leakage test of the cut surface: test group (n=40) and control group (n=40). The incidence of bile leakage and the risk factors were identified by analyzing the recipients, donors, and transplantation variables. Bile leakage occurred in 12.5% (10/80) of LDLTs. In the control group, there were nine cases of bile leakage (22.5%). On the other hand, there was only one case (2.5%) of bile leakage in the test group (P
