The Adenoma Detection Rate (ADR) is one of the quality measures in screening colonoscopy. The lower the ADR, the higher is the risk of cancers after colonoscopy. Endocuff is an endoscopic cap with plastic projections which permits to ﬂatten the colonic fold during withdrawal. Endocuff-Assisted colonoscopy (EAC) is potentially able to ameliorate the ADR which is crucial especially in a screening population.
To compare in a screening population: ADR, advanced adenoma detection rate (AADR) and number of adenoma detected between EAC and Standard colonoscopy (SC). Methods: We compared the performance of SC (from January to September 2014) and EAC (from January to September 2015) both in consecutive Fecal Immunochemical Test (FIT) positive and endoscopical FUP screening participants. Colonoscopy was performed by the same team of endoscopists in both 2014 and 2015. ADR was deﬁned as the number of colonoscopy with at least one adenoma divided by the total number of colonoscopies; mean number of adenoma per patient was deﬁne as the total number of detected adenomas divided by the number of colonoscopies; AADR as the number of colonoscopy with at least one advanced adenoma (deﬁned as an adenoma of 1cm or grater, or with villous/tubule- villous components or with high grade dysplasia) divided by the number of colonoscopies.
403 (198 F, mean age: 60.4 years, 49-70) and 445 (186 F, 60.2, 49-70) subjects performed SC and EAC respectively. ADR was 46% in SC and 53% in EAC, p<0.05. Mean number of adenoma per patient who undertook SC and EAC was 0.9 (range: 0-8) and 1.1 (range: 0-13) respectively, p<0.05. Advanced adenoma detection rate was 27% and 23% in SC and EAC respectively.
EAC increases both adenoma detection rate and the number of polyps detected. However, it does not ameliorate advanced adenoma detection rate.
