Meta-analysis: the comparison of clinical results between vaginal and laparoscopic myomectomy.
Summary of "Meta-analysis: the comparison of clinical results between vaginal and laparoscopic myomectomy."
To evaluate the clinical results of vaginal myomectomy and laparoscopic myomectomy (LM).
The database of PubMed, EMBASE, Web of Science, ProQuest, Cochrane library and China Biological Medicine Database (CBM), Chinese National Knowledge Infrastructure (CNKI), Wanfang (Chinese) and VIP (Chinese) were searched using the keywords "laparoscopic", "laparoscopically", "vaginal", "trasvaginal", "myomectomy", "randomized", "randomised" and "randomly" to identify randomized controlled trails which compared vaginal myomectomy and LM. Studies are also searched by hand. No language restrictions were made.
Four trials were studied and the analysis was performed using Review Manager Version 5 and R software Version 2.11.1. The results had shown that vaginal myomectomy was associated with less operation time significantly, but reduced blood loss, hospital stay and gas recovery and more minor complications without significant difference.
This meta-analysis was not powerful to form an accurate conclusion because of less number, low quality of included studies and no data on major complications and long-term outcomes such as recurrence and pregnancy. Hence, more studies and data should be awaited and involved for further evaluation.

Medical and Biotech [MESH] Definitions
Works consisting of studies using a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of literature.
A quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc., with application chiefly in the areas of research and medicine.
Comparison of outcomes, results, responses, etc for different techniques, therapeutic approaches or other inputs.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
The influence of study results on the chances of publication and the tendency of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or strength of the study findings. Publication bias has an impact on the interpretation of clinical trials and meta-analyses. Bias can be minimized by insistence by editors on high-quality research, thorough literature reviews, acknowledgement of conflicts of interest, modification of peer review practices, etc.
