Recurrent massive hemorrhage from the ileum as a late complication of radiotherapy has not previously been documented. We describe two patients with a history of pelvic radiotherapy 18 months and 11 yr before, in whom the source of melena was localized to the small bowel preoperatively. Characteristic serosal appearances of ileal radiation injury were present at laparotomy and resection of the terminal ileum controlled the hemorrhage. Pathological study revealed no ulceration but multiple telangiectatic vessels in the tips of mucosal villi. This cause should be considered in patients with obscure gastrointestinal bleeding previously exposed to pelvic radiotherapy.
回肠反复大量出血作为放疗的晚期并发症此前尚无文献记载。我们描述了两名患者，他们分别在18个月和11年前有盆腔放疗史，术前经检查确定黑便来源为小肠。剖腹手术时可见回肠放射性损伤的特征性浆膜表现，切除末端回肠后出血得到控制。病理研究显示无溃疡形成，但在黏膜绒毛尖端有多个扩张的毛细血管。对于有不明原因胃肠道出血且既往有盆腔放疗史的患者，应考虑这一病因。
