This systematic review and meta-analysis is aiming at how beneficial, and to what extent MIE resection really will be.MethodsA systematic literature search will be performed through May 31, 2018 using MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and Google Scholar for relevant articles published in any language. Randomized controlled trials, prospective cohort studies, and propensity score matched comparative studies will be included. If data are sufficient, subgroup analyses will be conducted in different surgical procedures of MIE.ResultsThe results of this systematic review and meta-analysis will be published in a peer-reviewed journal.ConclusionThis will be the first systematic review and meta-analysis using data of randomized controlled, prospective, and propensity score matched comparative studies to compare the outcomes between MIE and OE updating to May 31, 2018.
