The experience of biliary tract complications after liver transplantation

AIM: To report the morbidity and mortality of patients who undergo liver transplantation with or without T-tube implantation after choledochocholedochostomy as well as to discuss management of biliary complications. PATIENTS AND METHODS: We performed a retrospective review of 104 liver transplantations from August 2001 to February 2006, including 51 patients who underwent choledochocholedochostomy with a T-tube (group A) and 53, without a T-tube (group B). We compared the clinical characteristics, operative methods, biliary complications, morbidity, mortality, and management of complications. RESULTS: Between the two groups, there were no significant differences in clinical characteristics, including sex, age, and indication for liver transplantation (hepatitis B virus, hepatitis C virus, alcoholic liver cirrhosis, or hepatocellular carcinoma), Child-Pugh classification, Model for End-stage Liver Disease score, and operative macroscopic/microscopic findings. Additionally, there was no significant difference in biliary complications. Among these 104 patients, 14 (13.5%) developed biliary complications: seven anastomotic strictures, two intrahepatic duct strictures, two anastomotic stricture combined intrahepatic duct stricture, one bile leakage, one bile leakage combined with anastomotic stricture, and one external biliary compression. Nine patients with anastomotic stricture underwent endoscopy with a stent, which was successful only in two patients. The other six patients underwent choledochojejunostomy with excellent results. CONCLUSIONS: This study showed choledochocholedochostomy with or without a T-tube after liver transplantation did not influence the biliary complications. The biliary complications of anastomotic stricture after liver transplantation can be managed by endoscopy with a stent. If endoscopy fails, surgical intervention should be considered immediately.
