ERCP – Biliary

The practice of endoscopic retrograde cholangiopancreatography (ERCP) continues to attract a significant volume of clinical research, with a number of unanswered questions and new concepts being addressed within published literature over the past year. A selection of five important papers published in the past year is presented here.

Paclitaxel metallic stent for malignant biliary obstruction 1 Guide wire versus contrast injection for biliary cannulation: a randomized trial 2 Biliary sphincterotomy plus large balloon dilatation versus sphincterotomy alone for large bile duct stones 3 Plastic versus metal stents for malignant hilar obstruction 4 Complications following ERCP: results from a large, prospective multicenter study 5
