Abstract

Background and study aims The benefits of the new-generation CF290 (Olympus, Tokyo, Japan) for pancolonic chromoendoscopy (PCC) for colorectal polyp detection and its procedure time remain questionable. We compared the CF290 with the previous CF260 for PCC.

Methods We performed a propensity score-matching study using baseline characteristics such as age, sex, indications, endoscopist, and bowel preparation. We compared the detection of adenomas and sessile serrated polyps (SSPs) and procedure times of two expert endoscopists who performed PCC using the CF290 series (high-quality system with flushing pump) and the CF260 series (high-definition system).

Results We matched 374 patients who underwent PCC using the CF290 and 187 patients who underwent PCC using the CF260. The adenoma detection rate of the 290 series was higher than that of the 260 series, but not significantly. The SSP detection rate for the 290 series was higher than that for the 260 series (P = 0.01). Insertion time required for the 290 series was shorter than that required for the 260 series (P < 0.0001). Withdrawal time of the 290 series was shorter than that of the 260 series (P < 0.0001).

Conclusion Advanced technology can provide accuracy and help save time, and therefore, should be applied whenever possible.
