BackgroundInflammatory bowel diseases are gaining more interest in the past few years. Ulcerative colitis (UC) is a chronic disease that requires accurate follow-up for a good treatment plan. Colonoscopy alone cannot be efficient to detect disease extent and has a high risk of perforation in acute severe UC and toxic megacolon. Computed tomographic enterocolonography (CTE) is widely used now to detect intramural, extra-intestinal involvement and intestinal complications. Hence, this study aimed to evaluate CTE in the assessment of the degree of activity of UC.Patients And MethodsThis cross-sectional study was carried on 50 UC patients, divided into 36 males and 14 females presented at the Gastroenterology Unit, Alexandria Main University, Faculty of Medicine. Assessment of UC activity was done to all patients on three levels; the ulcerative colitis disease activity index for the clinical level, ulcerative colitis endoscopic index of severity by endoscopy and pathologically by degree of neutrophilic invasion, crypt abscess or cryptitis, presence of oedema and mucosal surface ulceration, then CTE was done and the findings were compared with the histopathological findings. Bowel wall thickening in CTE was divided into: normal (<3 mm, score 0), mild (3-6 mm, score 1), moderate (6-9 mm, score 2) and severe (>9 mm, score 3). Mesenteric hyperaemia, mucosal hyper enhancement and enlarged pericolic lymph nodes were recorded.ResultsCTE findings in the form of bowel wall thickening and hyper enhancement were found in 74% of active cases and were correlated with all histopathological findings investigated in this study with high statistical significance except in chronic stages, whereas lymph node enlargement and mesenteric hyperaemia did not show statistical significance with disease activity.ConclusionCTE is a good tool for diagnosing disease activity in UC.© 2021 John Wiley & Sons Ltd.
