Contribution of Colonoscopy After an Episode of Complicated Diverticular Disease

Aims Computed tomography (CT) is commonly used for the diagnosis of complicated diverticular disease. However, colonoscopy is generally recommended after an episode of complicated diverticular disease to rule out an underlying malignancy. The aim of our study is to investigate the value of this examination in patients with complicated diverticular disease of the colon.

Methods This is a retrospective study including all patients explored by colonoscopy after an episode of complicated diverticular disease between January 2017 and December 2019. Patients with colonic diverticular bleeding were excluded from our study.

Results We included 42 patients with a mean age of 61.5 years (43-85 years). These patients were divided into 18 men and 24 women. Diverticulosis was complicated by diverticulitis in 29 cases (69 %), perforation in 10 cases (24 %) and deep abscess in 3 cases (7 %). A favorable outcome was obtained after the introduction of antibiotic therapy in 76 % of cases. The remaining patients underwent surgical treatment (34 %). Colonoscopy was performed within 54 days after the acute episode (20 to 90 days). It showed diverticula in the sigmoid colon in 36 cases, the left colon in 25 cases, the transverse colon in 5 cases, the right colon in 5 cases and diffuse in 4 cases. Colonic polyps were present in 10 patients (24 %) with a mean size of 8 mm (5 to 12 mm). Histological examination showed two tubular adenomas with low grade dysplasia and two tubular adenomas with high grade dysplasia . No case of malignancy was observed.

Conclusions In our study, after an episode of complicated diverticulosis, colonoscopy was pathological in 24 % of cases. No cases of malignancy were observed.
