Abstract
The present study is a prospective cohort study evaluating the role of multi-detctor CT and CT enterography in the evaluation of inflammatory bowel disease, ulcerative colitis, and Crohn’s disease. The study included 30 patients with inflammatory bowel disease.
The mean age of our participants was 39.50±13. 13 years ranged from 20 to 68 years. Out of 30 studied participants, 13 (43%) were males and 17 (57%) were females.
The most common clinical presentations were abdominal pain and diarrhea, which were found in 15 (50%) of our studied participants, followed by weight loss in 12 (40%), melena in 10 (33%), bleeding per rectum in 7 (23%), fever, and positive family history in only one case (3%). The most commonly involved part of the colon was the right-sided colon (17,57%), followed by the left-sided colon (7,23%), and diffuse involvement of the colon in 6 (20%) of patients.
As regard the length of involvement, no cases suffered from focal involvement (< 5 cm), 13 (43%) had segmental involvement (6–40 cm), and 17 (57%) had diffuse involvement (>40 cm). Rectal involvement was observed in 12 (40%) of the studied patients. 19 (63%) cases showed mild (3–4 mm) bowel wall thickening, 9 (30%) cases showed moderate (5–9 mm) bowel wall thickening, and only two cases (7%) showed marked (> 10 mm) bowel wall thickening. Halo signs were observed in 8 (27%) and peri-colonic fat straining was observed in 22 (73%) of the studied patients.
10 (33%) have no lymph node involvement, 13 (43%) have no suspicious lymph node involvement (<1 cm), and 7 (23%) have suspicious lymph node involvement (≥1 cm). The Comb sign was observed in 19 (63%) of the studied patients. Also, CT enterography was able to detect small bowel involvement, extra-intestinal IBD manifestations, and complications.
