Endosopic view of the opening site of common bile duct (CBD) in the duodenal bulb

Slit – like ectopic openings of common bile duct (upper hole) and pancreatic duct (lower hole) with guide-wires inserted for the better demonstration.

"Excessive bile and/or bile precipitates in the gastric lumen was realized in all patients with ectopic opening of the common bile duct (CBD) into the duodenal bulb. Both the site and appearance of the choledochal entry in the bulb were unusual anatomically looking quite different from the major duodenal papilla. It was frequently located in the posterior wall of the bulb or close to the apex, slightly elevated from the mucosal surface and in some cases, like a cleft on level with the surface. In all visualized cases, pancreatic duct was opening separately next to the biliary orifice and was in a similar anatomic appearance. There was a deformity and stenosis in the bulb secondary to past ulcers in 26 subjects (49%) with an active duodenal ulcer in 8 of them.(Figure 2) In another 8 patients, anastomosis of a prior gastroenterostomy was observed. Gastric ulcer was seen in a single patient."
