Brief Summary

Screening colonoscopy for colorectal cancer is essential to diagnose and remove adenomas, precancerous stages of colorectal cancer. Unfortunately approximately 25 % of all adenomas are missed during the examination. Recently a new colonoscopy accessory, the Endorings-2 (EndoAid Ltd., Casearea, Israel), has been designed to improved the detection of adenomas during colonoscopy (adenoma detection rate). Endorings-2 is a silicone-rubber device that is fitted on the colonoscope and is equipped with circular flexible silicon rings mechanically stretching the colonic folds during withdrawal. This study aims to evaluate the efficacy of Endorings-2 to improve the adenoma detection rate in a prospective, blinded clinical trial. 292 patients with an indication for a screening colonoscopy shall be included (1:1 randomization in standard colonoscopy versus Endorings-2-assisted colonoscopy).

Outcome Measures

Primary Outcomes (1)

  • Evaluation of the adenoma detection rate during screening colonoscopy

    The primary outcome of this study is the adenoma detection rate of the standard colonoscopy in comparison to the Endorings-assisted colonoscopy.

    Intraoperative. Adenomas detected directly during the examination.

Study Arms (2)

Endorings-assisted screening colonoscopy

EXPERIMENTAL

146 patients with an indication for screening endoscopy will receive an Endorings-2-assisted colonoscopy.

Device: Endorings-2

Standard screening colonoscopy

NO INTERVENTION

146 patients with an indication for screening endoscopy will receive a standard colonoscopy.

Interventions

292 patients with an indication for screening colonoscopy will be included. 146 patients will receive a standard colonoscopy and 146 patients will receive an Endorings-2 assisted colonoscopy (1:1 standard colonoscopy vs Endorings-2-assisted colonoscopy).
