9 Minutes for Colonoscopy Withdrawal

Status Completed

Clinical Trial Summary

A withdrawal time of at least 6 minutes has been considered to be necessary to guarantee the adenoma detection rate and the critical quality criterion of colonoscopy. However, several large observational investigations demonstrated that 9 minutes will be in favor of higher adenoma detection rate and lower risk of interval colorectal cancer, when compared with 6-minute withdrawal. Meanwhile, a few studies also indicated that no significant benefit were observed in longer withdrawal time. Up to now, no randomized controlled trials have been conducted to give a definitive conclusion. Therefore, we performed a multicenter, prospective, randomized Controlled trial to compare adenoma detection rate of 6-minute and 9-minute withdrawal in colonoscopy.
