内視鏡的に切除できた十二指腸腺腫の1症例

Abstract

A 51-year-old man was found to have an abnormal polypoid lesion on UGIs of a health examination and was adrnitted to our hospital. Duodenogram showed a pedunculated polypoid lesion (12mm in diameter) in the third portion of the duodenum and endoscopic examination revealed that the surface was villous. The histological diagnosis of a biopsy specimen was villous adenoma. Endoscopic polypectomy was performed without any accidental complications. Histology of resected specimen revealed tubulo-villous adenoma with no malignancy. Although opportunities to detect duodenal polypoid lesions are increasing recently, tubulo-villous adenoma of the third portion of the duodenum is rare.
