Real-life experience of colonic polyps’ detection rate and adenoma detection rate with their characteristics in a cohort of Egyptian patients

Abstract

Background

Data on the prevalence of colonic polyps and adenomas in the Egyptian population are scarce. This study aimed to determine the prevalence of colonic polyps among Egyptian patients aged 50 years and older who underwent colonoscopy for a variety of reasons.

Patients and methods

This study is a retrospective one that was conducted with the use of an endoscopic reporting database of patients presenting at Cairo University Hospital. The considered variables were age, gender, clinical presentation, polyps’ characteristics, and diagnosis. Polyps were retrieved and sent for histopathological examination.

Results

Among 4861 patients whose clinical presentation necessitated colonoscopic examination between 2012 and 2019, 850 consecutive patients aged 50 years and older were enrolled in this study. The median age was 65 ± 9 SD. The male gender was slightly predominant (50.8%). The polyp detection rate was 23.1%, while the adenoma detection rate was 14.7%, and they were mostly encountered on the left side of the colon. By regression analysis, the most important predictors of adenoma were age ≥ 65 years, diabetes, and the presence of a polyp in the right colon. Diabetics and older people (≥ 65 years) had two times increased risk for adenoma, while patients with polyps in the right side of the colon had 30 times increased risk of adenoma.

Conclusion

PDR and ADR among the Egyptian population are matched to the target ADR set by the ASGE. We recommend ADR and PDR as key quality indicators of colonoscopy quality.
