Intraoperative donor cholangiography.

Biliary drainage has long been called the Achilles' heel of liver transplantation, and biliary complications compromise the success of liver transplantation by increasing graft loss and the rates of a required second operation, morbidity, and mortality. One cause of complications is unrecognized anomalous biliary anatomy. We examined 73 intraoperative donor duct cholangiograms (IODDCs) to assess our ability to identify biliary anomalies intraoperatively. Normal anatomy was seen in 42% (31/73); some part of the right-sided biliary system drained into the left bile duct in 22% (16/73); trifurcated systems with a single branch point for the right posterior, right anterior, and left ducts appeared in 16% (12/73); low insertion of a right segmental duct to the hepatic duct was seen in 11% (8/73); and drainage of a right segmental duct into the cystic duct or into the hepatic duct at the cystic duct origin was noted in 8% (6/73). It was believed that the last group represented a condition that dictated extra caution in biliary reconstruction. The incidence of radiographic recognition of these anomalies was more than twice the clinical recognition in our patient population, implying that many such "problem" ducts usually go unrecognized. IODDCs facilitate training of transplant fellows. Costs are low, and morbidity is nil. Copyright 1998 W.B. Saunders Company.
