Abstract

Introduction: This study evaluated the correlation of the presence of polyps and adenomas with respect to age, gender, and BMI in the context of AA as compared to Non-AA patients in the setting of colonoscopy screening and surveillance. Methods: A retrospective medical chart review was conducted on 1095 screening or surveillance colonoscopy patients in 2017 to determine whether the colonoscopies were completed and if a polyp was removed successfully and sent for pathological examination. Results: There were 376 patients with at least one adenoma and 635 with no adenoma detected (376/1011=37%) with the majority undergoing screening by academic gastroenterologists. Age (OR 2.4) and gender (OR 1.95) were primary risk factors in screening whereas age (OR 5.6) and race (OR 4.07) dominated surveillance. Non-AA patients had an increase in adenoma risk with an increase in BMI (OR 6.58) while AA patients had the opposite result (OR 0.32). AA patients undergoing surveillance were also more likely to have a polyp be an adenoma (78%) than Non-AA patients (37%). Conclusion: The fact that BMI in AA as compared to Non-AA patients was not associated with the risk of adenomas was an unexpected observation. The fact that if a polyp was found on surveillance in AA patients, it was more likely to be an adenoma than in Non-AA patients may suggest an increased emphasis on the importance of repeat colonoscopy after detection of an adenoma in AA patients at shorter intervals.
