Abstract

Endorings is a distal attachment consisting of two layers of circular flexible rings that evert mucosal folds.

Aims: Investigate if Endorings Colonoscopy (ER) improves polyp and adenoma detection compared to standard colonoscopy (SC).

Methods: Multi-centre, parallel group, randomised controlled trial.

Results: Total of 556 patients randomised to ER (275) or SC (281). Colonoscopy completed 532/556 (96%) cases. EndoRings removed in 74/275 (27%) patients. Total number of polyps in ER limb 582 vs 515 in SC limb, p=0.04. Total number of adenomas in ER limb 361 vs 343 for SC limb, p=0.49. A statistically significant difference in the mean number of polyps per patient in both the Intention to Treat (ITT) (1.84 SC vs 2.10 ER, p-value 0.027) and Per Protocol (PP) (1.84 SC vs 2.25 ER, p-value 0.004).

Conclusions: Our study shows promise for the EndoRings device to improve polyp detection.
