[Radiologic-endoscopic correlation in ulcerative colitis].

Double-contrast irrigoscopies (DCI) performed in 32 patients with confirmed ulcerative colitis are reviewed and correlated with colonoscopy. Whereas endoscopy proved more efficient in assessing superficial changes of the mucosa, DCI was found to be superior in the detection of deeper mucosal lesions and changes in the anatomic aspect of the colon wall. Moreover, DCI showed advantages in the evaluation of the entire colon including the coecum; examination of the coecum by endoscopy was achieved in 31% only of the scrutinised cases.
