"Hepar divisum"--as a rare donor complication after intraoperative mortality of the recipient of an intended living donor liver transplantation.

In this study, we present our experience with 4 healthy donors having the rare condition of "hepar divisum" after the intraoperative death of the recipient of an intended right adult living donor liver transplantation (LDLT). The study included 4 donors and 4 intended right LDLT recipients affected by neuroendocrine tumor (n = 2), hepatocellular carcinoma (n = 1), and cryptogenic cirrhosis (n = 1). All 4 recipients died intraoperatively. At the time of recipient death, the dissection of the donor liver parenchyma was complete, the vessels intact, and the hepatic duct(s) already divided. In each case, reconstruction of the donor biliary tract was performed: hepaticojejunostomy (HJ) in 2 cases, each with 3 ducts, and duct-to-duct anastomosis in 2. Of the donors receiving the HJ, 1 had a cut surface bile leak and the other experienced an anastomotic leak, treated by percutaneous drainage and reoperation, respectively. The latter patient experienced recurrent HJ stenosis at 44 months and 50 months after the operation and was treated by percutaneous balloon dilatation. One duct-to-duct reconstruction was complicated by early stenosis (postoperative day 6) and treated with endoscopic stenting. In conclusion, in the case of intraoperative death of the recipient of an intended LDLT, when the parenchyma and the hepatic duct of the donor have already been divided, the options are completion of the donor hepatectomy or the status of "fegatum divisum" with reconstruction of biliary tract. The high incidence of biliary complication, however, is of concern. When more than 1 hepatic duct is present, the donor hepatectomy should be completed and the graft reallocated according to the policy of the transplant institution. Copyright 2006 AASLD
