Abstract
A case of a large duodenal leiomyoma removed by endoscopic polypectomy is reported. A 36-year-old female was admitted to our hospital, complaining of epigastric colic. A diagnosis of cholecystolithiasis was made by ultrasonography, and cholecystectomy was carried out. However, the complaint persisted after the operation. Upper gastro-intestinal radiography performed again demonstrated a large duodenal tumor. Duodenoscopy revealed a giant, spherical tumor possessing a short, broad pedicle, a small ulcer at the top, and was covered with smooth mucosa. For the purpose of histopathological diagnosis and treatment, the tumor was removed by endoscopic polypectomy. The polypectomy was carried out twice, taking 30 minutes each time and being careful not to burn the duodenum. A part of the tumor remained but no massive hemorrhage was encountered, and the complaint disappeared. Histopathologically, the tumor was benign leiomyoma. The patient is at present being kept under close medical observation.
