The computed tomography scan characteristics of colonic diverticulitis

SUMMARY

Purpose: Describe the computed tomography (CT) scan characteristics of colonic diverticulitis (CD). Classification of colonic diverticulitis the World Emergency Surgery Society (WSES), and to compare computed tomography findings of right vs. left colonic diverticulitis.

Methods: Retrospective studies described case series of patients diagnosed Colonic Diverticulitis at University Medical Center hospital and there was CT scan between January and December 2018. Clinical features, treatmentwere collected and assess the characteristics CT scan of Colonic diverticulitis

Results: There were 104 patients, 75 right CD and 29 left CD. Mean age 46, ratio male/female 1,6. Inflamed diverticulum 89,4%; pericolic air bubbles19,2%; pericolic fluid 51,9%; abscess 1,7%; fistula 1,9%; bowel obstruction 1%. The classification of acute diverticulitis by the WSES, uncomplicated acute diverticulitis and complicated acute diverticulitisstage 1a, 1b, 2 a, 2b respectively of 48% and 39,2%; 6,9%; 4,9%; 1%. None of the complicated diverticulitis stage 3,4. Compare CT findings of right vs. left CD: Mean age (41 vs. 61), inflamed diverticulum (96% vs. 72,4%), pericolic air bubbles(8% vs. 48,3%), pericolic fluid (45,3% vs. 69%), abscess(4% vs. 31%), they differed significantly between the two groups (P < 0,05).

Conclusions: Diverticulitis is often right-sided, mild in severity. Most are uncomplicate and complicated diverticulitis stage 1a by the classification of WSES. Right CD occurs in younger and lower complications compared to left CD

Key words: Colonic diverticulitis,pericolic air, abscess,computed tomography findings, WSES.
