BACKGROUND/AIMS: Biliary tract complications are a common cause of morbidity and mortality after orthotopic liver transplantation. We report our experience in the use of ERCP in the treatment of post liver transplantation biliary complications. METHODOLOGY: Retrospectively we evaluated 34 patients who had undergone ERCP out of 460 who received a liver transplantation between January 1999 and December 2004. Eighteen patients presented biliary strictures, anastomotic in 12 cases and hilar in 6 cases; seven patients presented a biliary fistula and fifteen presented biliary stones in 8 cases associated to stricture and in 1 case to a fistula. Finally three patients underwent ERCP do to jaundice. The 18 patients with biliary strictures underwent sphincterotomy, dilation and stenting; the seven cases with fistulas were treated with a plastic biliary stent without sphincterotomy and the patients with biliary stones underwent sphincterotomy and endoscopic toilette of the common bile duct. RESULTS: An ERCP success rate of 97.7% was achieved without any significant complications. We obtained the resolution of all the biliary anastomotic strictures; resolution of hilar strictures was obtained in 66.6%. Biliary leak healed in 85.7% of patients. Complete endoscopic toilette was achieved in all the patients with biliary stones. CONCLUSIONS: In our experience ERCP has proved to be safe and effective in the treatment of post liver transplant biliary complications.
