We report a case of endoscopic removal of a denture with clasps impacted in the ileocecum. The patient was a 63-year-old man hospitalized at another center with aspiration pneumonia. He had a history of cerebral bleeding, inflicted permanent damage with left hemiplegia, and dysphagia. Abdominal radiography for localization of a catheter in the femoral vein revealed a denture in the right lower quadrant of the abdomen. He was subclinical and could not recall when he might have swallowed the denture. The patient was brought by ambulance to our institution. Computed tomography showed a foreign body with the density of metal in the ileocecum without any severe complications such as obstruction or perforation. Following intestinal lavage from a nasogastric tube, we performed colonoscopy and successfully retrieved the denture. The patient showed no complications associated with endoscopic therapy and returned to the previous hospital 3 days after endoscopic removal of the denture.
