ID: 3523296 COMBINED FORWARD AND RETROFLEXION WITHDRAWAL DURING COLONOSCOPY USING A SECOND-GENERATION SHORT-TURN RADIUS COLONOSCOPE

Abstract:

Methods a non-randomized, single-center prospective trial. Patients were submitted first to a standard high-definition screening colonoscopy. Then, a second procedure on the same patient combining forward and retroflexion was performed by a different operator. Lesions detected on the second procedure were considered as originally missed during standard colonoscopy. We calculated the polyp detection rate and the adenoma detection rate of both standard and combined colonoscopy techniques. Statistical analysis was performed on R. 4.0. 3. Results A total of 203 patients were included for analysis. The median age was 57 years, 66% were female. The reason for colonoscopy was diagnostic on 81.3%, screening on 15.8%, and 3.0% for surveillance. Regarding the size of the lesions, 74.5% of lesions detected on forward-viewing were< 5 mm. Whereas, on retroflexion 65.3% sized< 5mm and 34.7% between 5 …
