ADENOMA MISS RATE IN BACK-TO-BACK ENDOCUFF-ASSISTED COLONOSCOPY. A SINGLE-CENTER PROSPECTIVE STUDY. PRELIMINARY RESULTS

Aims To conduct a back-to-back endoscopy study and to evaluate the contribution of endocuff assisted colonoscopy to the detection of missed adenomas in a mixed population of colorectal cancer (CRC) screening/surveillance and symptomatic patients. To the best of our knowledge, this is the first study on this issue.

Methods It is a prospective study conducted from March 2021 to November 2021 in a tertiary endoscopy department. Two consecutive same day, endocuff assisted, colonoscopies were performed in 93 patients.

ClinicalTrials.gov Identifier: NCT04805567

Results 93 patients were enrolled (54.8% male/ median age 60 years). All examinations were complete (100% cecum intubation, 59.1% ileal intubation). The indications were CRC screening (62 patients, 66.7%), post-polypectomy surveillance (14 patients, 15.1%) and diagnostic assessment (17patients, 18.3%). 49.5% of the patients had diverticulosis. 257 polyps were overall found, 225 (87.54%) in the first examination in 73 patients and 32 (12.46%) in the second examination in 28 patients. Only 4 patients with no adenoma found in the first examination had one adenoma found in the second examination. The overall miss rate for adenomas was 12.65% and 13.89% for adenomas≥10mm.

Conclusions This back-to-back study has shown that endocuff- assisted colonoscopy has a low adenoma miss rate. These data further strengthen the existing evidence recommending the use of endocuff for decreasing the adenoma miss rate.
