Transhepatic Biliary Catheterization Before Graft Implant in Living Donor Liver Transplantation

Abstract

Aim Despite the evolution in surgical technique, the biliary anastomosis remains the technical Achilles' heel of liver transplantation, especially in living donor liver transplantation. Interventional radiology or endoscopic procedures constitute the most common options to treat complications from the biliary anastomosis. We report a novel technique to prevent biliary complications following the transplant. Methods During the donor procedure a wire guide was introduced in the severed duct, left or right, in retrograde fashion. The liver surface was then perforated and the wire guide exposed. A 4F catheter was then attached to the wire guide and pulled into the bile duct passing through the end-to-end duct-to-duct anastomosis or hepaticojejunostomy. Results This technique was performed in six living donor grafts: one right lobe, two left lobes, and three left lateral segments. All patients had no complications from the stent placement, biliary strictures, or leaks. One developed a hepatic artery thrombosis on the posttransplant day 14 with no major biliary complications.
