title: Formalin treatment of radiation-induced hemorrhagic proctitis.
abstract: A 71-year-old man developed severe hemorrhagic proctitis 1 year after pelvic irradiation for carcinoma of the urinary bladder. Conservative treatment as well as performance of a colostomy failed to control the rectal bleeding. After irrigation of the rectum with a formalin solution the bleeding stopped, and no recurrence has been observed for the next 14 months.
