Endoscopic diagnosis and resection of type B choledochocele. (A) Endoscopic view of second portion of duodenum demonstrates a pendulous mass in the duodenal lumen (asterisk). (B) The ampullary orifice (arrow) is located proximal to the lesion. (C) Cholangiography demonstrates filling of the choledochocele (asterisk) via a narrow communication with the intra-ampullary common channel (arrow). (D) After partially deflating the lesion with an aspiration needle, a snare is positioned around the neck of the cyst.
