Twelve patients underwent colonoscopy in addition to 9 patients who were examined by rigid rectoscopy. Endoscopic polypectomy was performed in 4 patients.Intravenous sedation was given to all cases. No life threatening complications occurred. Endoscopic procedures appeared more sensitive than barium contrast studies in the diagnosis of gastrointestinal diseases.
