252 – A Prospective Randomized Tandem Colonoscopy Study of Linked Color Imaging Or Narrow Band Imaging for Detection of Colorectal Polyp

Colorectal sessile serrated lesion detection using linked-color imaging versus narrow-band imaging: a parallel randomized controlled trial

“…So far, only one study has reported a comparison between NBI and LCI for colorectal polyp detection 12 . The authors performed a prospective, randomized, tandem colonoscopy study and showed that NBI resulted in a higher PDR, ADR, and percentage of serrated lesions than LCI.…”

“…The sample size calculation was performed using PASS software (version 15.0; NCSS, USA). According to a recent study that investigated LCI versus NBI for colorectal polyp detection, the serrated lesion detection rate was 22.1 % by LCI and 34.6 % by NBI 12 . The required sample size was calculated in an inequality test for two independent proportions using a two-sided Z test (unpooled), with a significance level of 0.05 and a statistical power of 80 %.…”

Advanced diagnostic endoscopy for colorectal tumors: Challenges that need to be solved in the years to come

“…Currently, distal attachment devices, especially Endocuff, have been shown to be effective in detecting lesions behind the folds in areas that are difficult to explore, and in increasing ADRs 6 7 . As for electronic chromoendoscopy, the first challenge for scientific societies such as ESGE is to decide if the use of these devices (and which ones?)…”

“…Currently, there is a certain policy of juxtaposition of technologies and non-aggression between the different endoscope companies. It would be preferable to move towards a policy of homogenization but to maintain a certain degree of competition 7 . A difficult challenge politically speaking!…”
