Abstract Background Yield of Endocuff-assisted colonoscopy (EAC) compared with standard colonoscopy is conflicting in terms of adenoma detection rate (ADR). A meta-analysis of randomized controlled trials (RCTs) appears necessary. Methods PubMed and Google Scholar were searched in December 2017. Abstracts from Digestive Disease Week and United European Gastroenterology Week meetings were also searched to 2017. All RCTs comparing EAC with standard colonoscopy were included. Analysis was conducted by using the Mantel–Haenszel models. Heterogeneity was quantified using the I 2 test. Results Of the 265 articles reviewed, 12 RCTs were included, with a total of 8376 patients (EAC group 4225; standard colonoscopy group 4151). In the meta-analysis, ADR was significantly increased in the EAC group vs. the standard colonoscopy group (41.3 % vs. 34.2 %; risk ratio [RR] = 1.20, 95 % confidence interval [CI] 1.06 to 1.36; P = 0.003; I 2 = 79 %), especially for operators with low-to-moderate ADRs (< 35 %): RR = 1.51, 95 %CI 1.35 to 1.69; P < 0.001; I 2 = 43 %). In contrast, this benefit was not reached for operators with high ADRs (> 45 %): RR = 1.01, 95 %CI 0.93 to 1.09; P = 0.87; I 2 = 0.0 %). The mean number of adenomas per patient tended to be higher with EAC (mean difference = 0.11 adenomas/patient, 95 %CI – 0.17 to 0.38). Similar results were shown for polyp detection rates (61.6 % vs. 51.4 %; RR = 1.20, 95 %CI 1.06 to 1.36; P = 0.004). Use of the Endocuff did not impact the cecal intubation rate (95.1 % vs. 95.7 %; P = 0.08), or the procedure time compared with standard colonoscopy. Adverse events related to Endocuff were rare and exclusively mild mucosal erosion (4.0 %; 95 %CI 2.0 % to 8.0 %). Conclusion With moderate-quality evidence, this study showed an improvement in ADR with EAC without major adverse events, especially for operators with low-to-moderate ADRs.

BackgroundHarmful alcohol use leads to a large burden of disease and disability which disportionately impacts LMICs. The World Health Organization and the Lancet have issued calls for this burden to be addressed, but issues remain, primarily due to gaps in information. While a variety of interventions have been shown to be effective at reducing alcohol use in HICs, their efficacy in LMICs have yet to be assessed. This systematic review describes the current published literature on alcohol interventions in LMICs and conducts a meta analysis of clinical trials evaluating interventions to reduce alcohol use and harms in LMICs.MethodsIn accordance with PRISMA guidelines we searched the electronic databases Pubmed, EMBASE, Scopus,Web of Science, Cochrane, and Psych Info. Articles were eligible if they evaluated an intervention targeting alcohol-related harm in LMICs. After a reference and citation analysis, we conducted a quality assessment per PRISMA protocol. A meta-analysis was performed on the 39 randomized controlled trials that evaluated an alcohol-related outcome.ResultsOf the 3,801 articles from the literature search, 87 articles from 25 LMICs fit the eligibility and inclusion criteria. Of these studies, 39 randomized controlled trials were included in the meta-analysis. Nine of these studies focused specifically on medication, while the others focused on brief motivational intervention, brain stimulation, AUDIT-based brief interventions, WHO ASSIST-based interventions, group based education, basic screening and interventions, brief psychological or counseling, dyadic relapse prevention, group counseling, CBT, motivational + PTSD based interview, and health promotion/awareness. Conclusion Issues in determining feasible options specific to LMICs arise from unstandardized interventions, unequal geographic distribution of intervention implementation, and uncertain effectiveness over time. Current research shows that brain stimulation, psychotherapy, and brief motivational interviews have the potential to be effective in LMIC settings, but further feasibility testing and efforts to standardize results are necessary to accurately assess their effectiveness.
