Introduction: There has been conflicting evidence regarding the role of surveillance colonoscopy after an episode of acute diverticulitis. Due to the paucity of clear recommendations; we aimed to determine the malignancy and polyp detection rates in patients over the age of 35 who had a recommended colonoscopy post an episode of diverticulitis. Method: This study was a single centre retrospective longitudinal study carried out at Tweed Hospital in New South Wales. Study approval was obtained from the Northern NSW LHD ethics committee. The study included all patients admitted with diverticulitis between January 2022 – 2023. Data was retrospectively collected and assessed as per our inclusion and exclusion criteria. Results: 108 patients were included in the study. 73 patients (68%) had uncomplicated diverticulitis and 35 patients (32%) had complicated diverticulitis. 60% of patients with complicated diverticulitis (n= 21) had a follow up colonoscopy and polyp detection rate was 38%. In the uncomplicated diverticulitis group, 75% of patients (n=55) had a follow up colonoscopy and the polyp detection rate was 35%. There were no malignancies found in the study. The overall follow up rate of this cohort was 70%. Conclusion: There were no malignancies found in this patient cohort following routine surveillance colonoscopy. The risk of polyps appears to be similar in patients with uncomplicated and complicated diverticulitis. Overall, the rate of polyp detection appeared to be slightly higher than the general screening population.
