Gastroenterology fellows detect more polyps, and more advanced lesions, when they use underwater colonoscopy instead of air insufflation, a new study shows.
The study, involving 29 GI fellows at the University of California, Irvine, over a five-year period, found that underwater colonoscopy resulted in rates of polyp detection (PDR), adenoma detection (ADR) and identification of sessile serrated adenomas (SSADRs) that exceed traditional air insufflation (Table, Figure).
