title: [Rectoscopy and Hemoccult II in irritable colon. A prospective study].
abstract: It was investigated whether Hemoccult-II test (H-II) could reduce the number of colonic examinations in patients with the irritable bowel syndrome, with normal rigid proctoscopic findings. A negative H-II was obtained in 299 patients from general practice and a positive test in nine. Colonoscopy was done in 157 and double contrast barium enema in 142 after random allocation. The nine patients with positive H-II all had colonoscopy. Among the 299 with negative H-II, colonic adenomas were detected in ten and an early cancer in an adenoma in the sigmoid colon; overlooked rectal adenomas were found in three, rectal cancer in one, rectal carcinoid in another and a coecal cancer, which could be palpated, in a third patient. Two patients with colonic cancer and one with adenoma were detected among those with positive H-II. All patients were followed by clinical examination after one year. In conclusion, colonic examination should carry a low priority in patients with symptoms of irritable bowel, negative Hemoccult-II and normal rigid proctoscopic findings performed by an experienced examiner. The investigation confirmed the recommendation of total colonoscopy in patients with a positive H-II and added support for increasing number of endoscopy services in contrast to those of diagnostic radiology, which should be reduced.
