Biliary complications following orthotopic liver transplantation.

The gall-bladder conduit anastomosis (choledocho-cholecysto-choledochostomy) has been the most frequently used technique for the biliary tract anastomosis in the Cambridge/King's College Hospital joint liver transplantation programme since 1976. Cholangiograms and interventional biliary procedures performed over a 3 year period were reviewed retrospectively. Seventy-six of 148 patients managed post-operatively at King's College Hospital were studied (79 transplants). Cholangiograms were abnormal in 63 (80%) transplants with biliary strictures; inspissated bile formation, bile leak and T-tube malposition occurring in 50, 23, 14 and three transplants respectively. Anastomotic strictures occurred most frequently, predominantly at the proximal anastomosis, and the presence of inspissated bile and the T-tube in relation to these contributed towards subsequent biliary obstruction. Non-anastomotic strictures in the donor biliary tract were associated with a high position of the T-tube tip at or above the liver hilum. Saline irrigation of the bile ducts for inspissated bile or its removal via the endoscope were effective measures in the management of biliary obstruction but percutaneous balloon dilatation and endoscopic stent insertion for biliary strictures were found to have a limited role.
