1. Biliary duct injury are a relatively frequent complication of hepatobiliary surgery, most comonly laparoscopic cholecystecomy. 2. Prior to the development of more sophisticated endoscopic interventions, repeat surgery was often necessary for the management of biliary leaks. 3. Advances in technique and technology in gastroenterology endoscopy have largely replaced surgery as the first line intervention for biliary leak. 4. Most practices utilize endoscopic plastic biliary stent placement alone and are efficacious and equivalent to the biliary stent placement with endoscopic biliary sphincterotomy. 5. An area of variation is in whether biliary stent should cross the papilla ( with a shorter stent) versus the site of the bile leak (with a longer stent). 6. Our objective is to assess whether placing a biliary stent across the leak versus across the papilla alone improves the treatment of biliary leaks.
