自然脱落が推定された早期大腸癌の1例

抄録

A 44-year-old woman was admitted to our hospital because of bright bleeding per anus. After colonoscopy, it was suggested that the cause of bleeding was due to autoamputation of semipedunculated polyp in the transverse colon. Initially, endoscopic clipping was performed to prevent re-bleeding. Laparoscopic partial resection was performed because the pathological diagnosis of the biopsy specimen taken from the lesion suggested highly carcinoma. The residual lesion was well differentiated adenocarcinoma limited in the mucosal layer.
