Routine endoscopic retrograde cholangiography in the detection of early biliary complications after liver transplantation.

Abstract

The value of routinely performing endoscopic retrograde cholangiography (ERC) to detect biliary complications in patients undergoing orthotopic liver transplantation (OLT) with duct-to-duct anastomosis without a T-tube is not known. Eighty-nine of 171 liver transplant recipients (61 men; mean age, 49.9 years) underwent ERC 14.5 +/- 4.5 (SD) days after surgery between January 1997 and August 1999. Findings of ERC and need for intervention for biliary complications were noted. ERC was successful in 71of 89 patients (80%). Nineteen patients (21%) required intervention for biliary complications (stricture, 13 patients; bile leak, 6 patients). Protocol ERC detected eight of these complications (42%). In 4 patients, ERC failed, and 7 patients with a normal ERC result subsequently required intervention (2 patients in the same admission, and 5 patients after discharge). Sensitivity, specificity, and positive and negative predictive values for successful ERC in detecting early biliary complications were 80%, 98%, 89%, and 97%, whereas those for predicting the overall rate of biliary complications were 53%, 98%, 89%, and 89%, respectively. Although highly specific and moderately sensitive in detecting early biliary complications, ERC performed routinely has low sensitivity in predicting the overall risk for biliary complications in patients undergoing OLT with unsplinted duct-to-duct anastomosis.
