Background and study aim Different techniques have been introduced to improve the endoscopist’s view and enhance the detection of polyps. The endocuff is a polymer sleeve cap that is connected to the tip of the colonoscope in order to improve visualization of the mucosa during colonoscopy. The aim of the study was to compare adenoma detection rates (ADR) of endocuff-assisted colonoscopy and conventional colonoscopy.

Patients and methods Patients 50 years or older were randomized into two groups: an endocuff-assisted colonoscopy group and a conventional colonoscopy group without the endocuff.

Results A total of 337 patients were included: 174 in the endocuff group and 163 in the conventional group. The median age was 61 years (interquartile range 55 – 70 years), and 74 % were women. The ADR was higher in the endocuff group than in the conventional group (22.4 % vs. 13.5 %; P = 0.02). The mean number of adenomas was 0.30 (SD 0.25) in the endocuff group and 0.21 (SD 0.26) in the conventional group ( = 0.02). The rate of ileal intubation was lower in the endocuff group (73 % vs. 87 %; P < 0.001). No serious adverse events occurred with the use of the endocuff.

Conclusions Endocuff colonoscopy achieved a greater ADR than conventional colonoscopy.
