Two patients are presented in whom ischaemic colitis followed some years after abdomino-perineal excision of the rectum for carcinoma. The first patient was a young man without evidence of arterial disease and the second patient suffered from auricular fibrillation, thought to be due to ischaemic heart disease. Ligation of the inferior mesenteric artery in the operation of abdomino-perineal excision of the rectum may reduce the blood flow through the marginal artery of Drummond rendering the remaining colon more liable to ischaemic damage. Patients who pass bright blood through a colostomy following abdomino-perineal excision of the rectum for carcinoma may have ischaemic colitis rather than a recurrence of the neoplasm.
本文介绍了两名患者，他们在因癌行腹会阴直肠切除术后数年发生了缺血性结肠炎。首例患者为一名无动脉疾病证据的年轻人，第二例患者患有心房颤动，被认为是由缺血性心脏病所致。在腹会阴直肠切除术中结扎肠系膜下动脉可能会减少通过Drummond边缘动脉的血流，使剩余结肠更易发生缺血性损伤。因癌行腹会阴直肠切除术后通过结肠造口排出鲜血的患者可能患有缺血性结肠炎而非肿瘤复发。
