title: External biliary fistula in orthotopic liver transplantation.
abstract: During orthotopic liver transplantation (OLT), various situations may occur in which biliary reconstruction is neither technically feasible nor recommended. One bridge to a delayed anastomosis can be an external biliary fistula (EBF). This procedure allows the surgeon to execute hemostatic maneuvers, such as abdominal packing; therefore, biliary reconstruction can be subsequently performed in a bloodless operative field without edematous tissues. EBF can be made by placing in the donor biliary tract a cannula that is fixed to the bile duct using 2-0 silk ties and secured outside the abdominal wall. The biliary anastomosis will be performed within 2 days after the OLT. The aim of this study was to examine the safety of EBF in terms of the incidence of biliary complications compared with a direct anastomosis. Among 1,634 adult OLTs performed in 17 years in our center, 1,322 were carried out with termino-terminal hepaticocholedochostomy (HC-TT); two with side-to-side hepaticocholedochostomy; 208 with hepaticojejunostomy (HJ); 31 with EBF and delayed HC-TT, and 71 with EBF and delayed HJ. Biliary complication rates in the EBF group were 24.5%, including 23.9% in the delayed HJ and 25.8% in the delayed HC-TT. Biliary complication incidence among all OLTs was 24.6% (P = NS). No complications related to the procedure were observed. Therefore, EBF is a safe technique without a higher biliary complication rate. It may be useful when a direct biliary anastomosis is dangerous.
