BACKGROUND: Radiotherapy within pelvis is a vital component of curative therapy for urological, gynecological and rectal malignances. Rectum is especially vulnerable to secondary radiation injury resulting in proctitis. The most common and life-threatening symptom is rectal hemorrhage. Formalin application into the rectum causes local cauterization of telangiectatic mucosal vessels. The aim of our study was to assess the efficacy of local formalin application in patients with hemorrhagic radiation proctitis. METHODS: A solution of 4.0% formalin was used in the treatment of 20 patients with clinical and proctoscopic evidence of radiadion proctitis. Treatment involved direct application of 4.0% formalin into the rectum. All patients were followed-up in terms of complete resolution of symptoms or recurrences of bleeding. RESULTS: A total of 20 patients with a mean age of 69.7 (range, 57-80) years were followed for 51.2 (range, 1-93) months. The mean duration of symptoms was 4.5 (range, 1-10) months and the interval between the end of radiotherapy and symptoms was mostly between 5 and 30 months. Patients required an average of 2 (range, 1-5) formalin treatments. Of the 20 patients, 10 had complete resolution of their symptoms after their first treatment. In 10 patients bleeding recurred and they were offered another formalin instillation and/or 5-ASA suppositories and argon therapy. Complete resolution of symptoms was achieved in all patients. CONCLUSIONS: Topical formalin instillation is effective, safe, and well-tolerated method for the patients with radiation proctopathy. This therapy may be repeated in case of recurrent bleeding and combined with other methods of treatment.
