ERCP and Direct Cholangioscopy with Gastroscope in Patients with Ectopic Opening of the Bile Duct into the Duodenal Bulb: A Report of 3 Cases.

Ectopic openings of the common bile duct into the duodenal bulb, which are associated with biliary tract disease or recurrent/refractory duodenal ulcers, are rare. We report three such cases, all of which were documented with gastroscope, and two of which were managed with endoscopic retrograde cholangiopancreatography (ERCP) via gastroscope. We suggest that ERCP can be performed with gastroscope, since it may offer a better working position in certain cases. [ABSTRACT FROM AUTHOR]
