title: The diagnosis of colitis by colonoscopy with biopsy and X-ray examination. A blind comparative study.
abstract: The examinations were performed in 40 outpatients, of whom 21 were women. From the rectal and colonic mucosa 185 biopsies were obtained. The X-ray examination was performed within one week from the colonoscopy, using a conventional barium enema. A complete agreement between the colonoscopic diagnosis and that of the directed biopsy was found in 33 cases (80 per cent), and minor disagreements in 3 cases. A complete agreement between the colonoscopic and X-ray diagnoses was obtained in 22 patients (55 per cent), and minor disagreements in 16 cases, most of whom showed "unspecific" non-ulcerative colitis. In 3 cases with ulcerative colitis a normal colon was found by X-ray. A higher percentage of cases showed decreased haustration by X-ray examination than by colonoscopy, whereas a fairly equal percentage of ulceration was detected by the two methods. Erosions, mucus covering, oedema, vascular injection, and bleedings were not detected by X-ray examination.
