| Abstract: | Abstract: We report two duodenal adenoma cases treated by endoscopic polypectomy. Case 1, a 59-year-old male, visited our hospital for further examination of a duodenal polyp found elsewhere. X-ray examination revealed a semi-pedunculated polyp with an irregular surface in the second portion of the posterior wall of the duodenum. Case 2, a 68-year-old male, was admitted to our hospital for endoscopic polypectomy of a duodenal polyp. Upper GI series demonstrated a semi-pedunculated round polyp with a shallow central depression. Endoscopic polypectomy was performed for both lesions and the polyps were successfully removed. The resected polyps were 11 × 10 mm and 13 × 12 mm in size, respectively. The polyps were histologically diagnosed as tubulovillous and tubular adenomas, respectively, with no evidence of malignancy. Endoscopic polypectomy provides histological confirmation of adenoma of the gastrointestinal tract, and it is frequently applicable to the duodenum. |
