Abstract

Two cases are herein reported involving patients with ectopic gallstones which were discharged into the stomach and duodenum through a cholecystoduodenal fistula and successfully removed by endoscopic therapy. In the first case, a 75-year-old man was admitted with epigastric pain. Simple abdomen film demonstrated a round laminated calcification and air biliarygram in the RUQ. Endoscopic examination revealed a fistula on the posterior wall of the duodenal bulb and a brown stone (about 5 cm in diameter) was found in the second portion of the duodenum, It was demolished through endoscopic electrohydraulic lithotripsy (EEH1) and discharged with the stool. In the second case, a 55-year-old man was admitted with epigastric pain. A CT scan revealed an ovoid laminated calcification in the dependent portion of the stomach. Endoscopic examination revealed a fistula on the anterior wa11 of' the duodenal bulb and a black pigmented stone (about 2.5 cm in diameter) was found in the stomach. This stone was removed orally by an endoscopic snare. These patients were discharged and remained asymptomatic. (Korean J Gastrointest Endose 2000;20:491-495)
