Presentation and Surgical Management of Duodenal Duplication in Adults

Figure 2

Preoperative endoscopic imaging. The second and third portions of the duodenum were noted to be markedly dilated with an accompanying finding of three downstream orifices. At this time, it was felt that the medial orifice (1) was the duplication and the lateral orifice (2) was the true lumen and that orifice (3) represented a distal common channel. White arrow denotes area of biliopancreatic ampulla which was proximal to the duplication.
