No results posted yet for this study

Summary

A prospective multicenter randomized controlled trial (RCT) comparing water exchange (WE) colonoscopy and carbon dioxide (CO2) insufflation in terms of right colon combined adenoma miss rate (AMR) and hyperplastic polyp miss rate (HPMR) by tandem inspection.

Conditions

  • Right Colon Adenoma Miss Rate
  • Right Colon Hyperplastic Polyp Miss Rate

Interventions

PROCEDURE

Colon Polypectomy

Polyp search and resection will be performed entirely during the withdrawal phase in both WE and CO2 groups. Insertion inspection and polypectomy will not be performed. All polyps in the proximal colon, defined as cecum, ascending colon, hepatic flexure, and transverse colon, will be removed irrespective of their size and appearance.
