Massive Bleeding from the Ileum: a Late Complication of Pelvic Radiotherapy
Blood Coagulation Factors
Lupus Erythematosus, Systemic
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.
