RÉSUMÉ
PURPOSE: Living donor liver transplantation (LDLT) has several difficulties in biliary reconstruction of the small and thin bile duct, the short stump, and multiple openings. METHODS: 76 cases of LDLT performed in Asan Medical Center from Jan. 1999 to Feb. 2000 were reviewed retrospectively. RESULTS: The causative diseases in this group were hepatitis B associated cirrhosis 47, hepatoma 16, fulminent hepatic failure 6, secondary biliary cirrhosis 3, alcoholic cirrhosis 2, hepatitis C associated cirrhosis 1, and Wilson's disease 1cases. Right lobe graft was done in 54 cases, and a left lobe graft was done in 22. All bile duct reconstructions were done as Roux-en-Y hepaticojejunostomy, single anastomosis in 59, a double anastomosis in 15, and a triple anastomosis in 2cases. Biliary leakage occurred in 7 cases (10.4%), and percutaneous drainage subsequently being done. Post leakage bile duct stricture occurred in 2 cases (2.6%). Delayed bile duct stricture occurred in 3 cases. All stricture cases were treated with PTBD and repeated balloon dilatation. There was no difference between the right and left lobe graft in terms of bile leakage. However, stricture, occurred only in the right lobe graft. Bile duct stricture occurred more frequently in the multiple bile ducts (5% in single duct, 13.3% in double ducts, but there's no significance). CONCLUSION: The prevalence of biliary complication of LDLT was about 10%. In addition, there were more complicationsin the right lobe and multiple bile duct openings. Therefore, careful design and delicate hepatic parenchymal dissection is important to obtain a single duct and safe cut surface of the graft. To avoid severe complications such as an intrahepatic abscess or stone, early diagnosis and treatment of biliary complications is essential.
