The effect of adding gentamicin to contrast media for prevention of cholangitis after biliary stenting for non-calculous biliary obstruction, a randomized controlled trial.

Aim: Cholangitis is the most common infectious complication of ERCP. In vitro studies showed that addition of aminoglycosides to contrast medium was effective in reducing cholangitis but the results of clinical trials are conflicting. We studied the effect of adding gentamicin to contrast medium in reducing the rate of post-ERCP cholangitis in patients with non-calculous obstructive jaundice.
