- W2912054745 abstract "Introduction: Underwater colonoscopy has been associated with increased patient tolerance and decreased need for sedation compared to traditional air-insufflation colonoscopy. The effect of underwater colonoscopy on polyp detection has not been as thoroughly assessed, especially among those in gastroenterology fellowship. Our objective was to determine if GI fellows performing underwater colonoscopies have higher detection rates of polyps, adenoma and sessile serrated adenomas compared to fellows performing air-insufflation colonoscopies.Figure: Percent Improvement in Detection Rates with Underwater vs. Air-Insufflation Colonoscopy.Table: Table. Baseline CharacteristicsTable: Table. Average Polyp Detection Rates in Underwater vs. Air-Insufflated ColonoscopyMethods: Colonoscopy quality data was collected prospectively at our single tertiary referral center from June 2012 to May 2017 using Qualoscopy (Docbot, Inc.). 29 GI fellows performed 2270 colonoscopies (1237 underwater (UW) and 1033 air-insufflation (AI)). UW and AI cases were compared for detection rates of polyps (PDR), adenomas (ADR), and sessile serrated adenoma (SSADR), as well as procedure times and cecal intubation rates. Subgroup analysis included polyp location. Significance was determined by a two-tailed Fischer's exact test and T-test. Results: UW compared to AI was associated with a higher PDR (77.0% vs. 69.3%, P=0.0001), ADR (53.1% vs. 48.2%, P=0.02) and SSDAR (15.6% vs. 10.2%, P=0.0001) among fellow-performed colonoscopies. Significant differences were retained in the left colon for ADR (29.2% vs. 23.6%, P=0.003) and SSADR (7.10% vs. 3.20%, P=0.0001). In the right colon, significant differences were retained for PDR (60.9% vs. 50.5%, P=0.0001) and SSADR (13.0% vs. 9.60%, P=0.01). Insertion time (14.1 vs. 13.9min, P=0.96), withdrawal time (24.5 vs. 21.9min, P=0.29), total time (38.6 vs. 35.8min, P=0.46) and cecal intubation rates (98.9% vs. 98.8%, P=0.44) were similar within UW and AI colonoscopy, respectively. Conclusion: GI fellow-performed UW colonoscopy compared to air-insufflation colonoscopy is associated with higher PDR, ADR and SSDAR. This data supports future prospective randomized studies to verify improved polyp detection with underwater colonoscopy and suggest that underwater techniques should be included in the training curriculum of GI fellows to further improve colonoscopy quality and reduce interval colorectal cancers." @default.
