IDDF2022-ABS-0227 Quantifying the impact of symptoms on colonoscopy findings: patients with change in bowel habits are twice more likely to have high-risk adenomas

BackgroundThis study aims to determine the prevalence rates of polyps and adenomas in patients with a change in bowel habits (CIBH) using a tertiary single-institution endoscopic database.Methods80,651 consecutive patients undergoing colonoscopy at National University Hospital, Singapore, between March 2014 – December 2019 were included. 5929 patients with CIBH suggestive of colonic disease without evidence of gastrointestinal bleeding were compared against 13164 asymptomatic patients undergoing screening colonoscopy. Endoscopic data of polyps were verified with histological reports to determine cases of adenoma and dysplasia.Results7.35% of colonoscopies were performed for patients with CIBH. Patients with CIBH were slightly older (59.4±12.9 vs 59±10.1 years old, p=0.01), but of similar gender (male: 53.9% vs 53%), compared to asymptomatic controls undergoing screening. Patients with CIBH have lower polyp rates (34.6% vs 40.9% p
