Table of Contents

Pyogenic granuloma is a polypoid form of capillary hemangioma that occurs mostly on the skin and the mucous membranes of the nasal and oral cavities [1]. Although pyogenic granuloma in the digestive tract excluding the oral cavity is a rarity, it can cause significant gastrointestinal bleeding, and curative resection is required for treatment in most cases [2]. We describe a case of pyogenic granuloma of the common bile duct (CBD) that was observed on endoscopy and was successfully treated by endoscopic snare polypectomy.

A 69-year-old woman was admitted to our hospital with a 1-day history of right upper quadrant pain. She had a history of cholecystectomy and CBD exploration with side-to-side choledochoduodenostomy and recurrent attacks of cholangitis. On endoscopic retrograde cholangiography (ERC) using an Olympus duodenoscope (JF-240; Olympus Optical Co., Tokyo, Japan), the CBD was cannulated with a balloon catheter through the wide stoma of the side-to-side choledochoduodenostomy ([Fig. 1] a) and the CBD visualized. A nonmovable, small, round filling defect was noted in the dilated distal CBD ([Fig. 1] b). Because of the wide stoma of the choledochoduodenostomy and the dilated CBD, it was possible to insert a forward-viewing endoscope (Olympus GIF-Q260; Olympus Optical Co.) through the stoma into the distal CBD. This showed a semipedunculated, smooth polypoid lesion that was 5 mm in diameter, hyperemic, and dark red in the distal CBD, with a tinge of blood on its surface ([Fig. 2] a). The lesion was removed by snare polypectomy without any complications ([Fig. 2] b). On the basis of histopathological analysis of the resected tissue ([Fig. 3]), the lesion was diagnosed as a pyogenic granuloma. To the best of our knowledge, this is the first reported case of pyogenic granuloma in the bile duct.
