ERCP in orthotopic liver transplanted patients

BACKGROUND/AIMS: Biliary complications after orthotopic liver transplantation (OLT) are still common. The aim of the study was to assess the effectiveness of ERCP as a diagnostic and treatment tool in the management of biliary tract OLT complications. METHODOLOGY: The diagnostic and treatment effectiveness of ERCP in the management of biliary tract OLT complication from 1/1995 to 12/2001 was reviewed. RESULTS: 24/251 (9.6%) OLT patients presented biliary complications. These patients underwent a total of 31 ERCP (seven patients received two ERCP). The ERCP indication was cholestasis in 25 (80.6%). The success rate of these 31 ERCPs was 87%. In the 25 ERCPs indicated in patients with cholestasis, the procedure revealed strictures of the biliary anastomosis in 3, hepatic hilum strictures in 5, SOD in 4, lithiasis in 7 and sclerosing cholangitis in one. The final diagnosis of three patients with normal biliary tract was intrahepatic cholestasis. In three of the four patients with biliary leaks the ERCP's confirmed the diagnosis. The final treatment efficacy was 100% (7/7 patients), 50% (2/4 p.), 0% (0/3 p.), 75% (3/4 p.) and 100% (4/4 p.) for patients with biliary stones, strictures of the hilum, anastomotic strictures, biliary leaks and SOD, respectively. In the acute pancreatitis and in the PSC endoscopic treatment was not indicated. There were two mild cases of pancreatitis. CONCLUSIONS: Because of its availability, diagnostic accuracy, treatment efficacy and safety, ERCP should be used as the first-line procedure for treatment of biliary tract complications after OLT.
