Objective: This meta-analysis aimed to evaluate whether EndoCuff-assisted colonoscopy (EAC) could improve adenoma detection rate (ADR) compared with standard colonoscopy (SC).
Methods: PubMed, EMBASE, Scopus, Cochrane Library, and Google Scholar databases were searched for articles published up to March 2019. All pure randomized controlled trials comparing ADR between EAC and SC groups were included. Dichotomous data were pooled to obtain the odds ratio with a 95% confidence interval (CI), whereas continuous data were pooled using a mean difference with 95% CI. Review Manager Version 5.3 was used for data analysis.
Results: Thirteen randomized controlled trials consisting of 9038 patients (EAC: 4574; SC: 4464) were included. The EAC group showed significant superiority over the SC group in ADR (odds ratio 1.37, 95% CI 1.15-1.62). However, there were no differences between the EAC and SC groups in adverse events, cecal intubation rate, and cecal intubation time.
Conclusions: EAC could significantly improve ADR without increasing adverse events, especially for operators with low ADRs. In addition, no significant difference was observed in cecal intubation time and cecal intubation rate between EAC and SC.
