INTRODCUTION:
Although colonoscopy is considered the optimal procedure for bowel cancer screening, it remains an imperfect tool for cancer prevention, due to missed adenomas and early cancers. The Endocuff is a simple device attached at the end of the colonoscope that opens the field of view by retracting folds during withdrawal. Little is known regarding the Endocuff’s impact on a colonoscopist’s performance.

AIMS and METHODS:
The aim of this study was to evaluate the impact of the Endocuff-visionTM (ARC Design Ltd, UK) on the quality indicators for each operator. A prospective observational evaluation study was performed from April 2013 to September 2014, divided in three consecutive periods: pre-cuff (no device used), during-cuff (device used) and post-cuff (no device used). Four screening endoscopists (BPS, STG, NS, AH) utilized the Endocuff-visionTM at their own discretion when device was available to them. Quality colonoscopy indicators {(Adenoma Detection Rate (ADR), Mean number of adenomas per procedure (- MAP), Caecal intubation time (CIT)} were analyzed (t-test two sample assuming equal variances) in equivalent number of procedures. The total number of procedures performed was 399, 133 per period (BPS/26, STG/53, NS/31, AH/23).

RESULTS:
The mean ADR was 55.13% in the pre-cuff period, 68.98% in the during-cuff period and 61.74% in the post-cuff period. All four operators showed significant improvement in detection when using the device, which resulted in an overall increased ADR of13.8%(p!0.05). During the post-cuff period, the detection performance of the three endoscopists declined while maintaining a high detection rate. The mean MAP was 1.2 in the pre-cuff period, 2.2 in the during-cuff period and 1.55 in the post-cuff period. The mean MAP increased significantly in all four operators at the during-cuff period (83%,p!0.05). During the post-cuff, 3 endoscopists returned almost to the baseline MAP pre-cuff level. The mean CIT was 9.66 min in the pre-cuff period, 7.5 min in the during-cuff period and 9.54 min in the post-cuff period. A decrease in mean CIT was featured (22.36%, p!0.005) to all operators when using the device, returning to about the pre-cuff levels afterwards. No complications were reported from the use of the Endocuff-vision although it was electively removed in 4 cases with severe sigmoid colon diverticulosis and one case due to anal discomfort.

CONCLUSION:
In this study, use of the Endocuff-visionTM improved overall performance by making colonoscopy a quicker (CIT) and more efficient (MAP/ADR) procedure. Further randomized evaluation of this simple novel device is warranted.

  • The Endocuff is feasible, safe, reliable and easy to handle and might have potential to reduce the incidence of colorectal cancer

  • My colleagues and I have definitely found polyps that they didn’t see with the forward view. We feel we were doing an excellent exam with current colonoscopy and that this made it better.
