title: An impacted clamshell in the duodenum mistaken for a gall stone.
abstract: Although most ingested foreign bodies pass through the gastrointestinal tract spontaneously, those that are sharp, pointed, or large require removal to avoid serious complications. Here we report an interesting case of a 60-year-old man who swallowed a clamshell that passed through the pylorus and was caught in the duodenum. Radiologic findings made it look like a biliary stone. Endoscopic retrieval of the clamshell with a Dormia Basket was performed safely and the patient was discharged uneventfully on the day of the procedure.
