Efficacy and safety of Buzhong Yiqi decoction combined with surgery for rectal prolapse: A protocol for systematic review and meta analysis.

BACKGROUND: It is extremely easy for rectal prolapse to relapse with surgery alone. Clinical practice indicates that Buzhong Yiqi decoction combined with surgery has certain therapeutic advantages, while there is a lack of evidence-based medicine support. This study aimed to systematically investigate the efficacy and safety of Buzhong Yiqi decoction combined with surgery in the treatment of rectal prolapse. METHODS: The English databases (PubMed, Embase, Web of Science, the Cochrane Library) and Chinese databases (China National Knowledge Infrastructure [CNKI], Wanfang, China Science and Technology Journal Database [VIP], China Biology Medicine disc) were searched by computer. In addition, Baidu Scholar and Google Scholar were searched manually. A randomized controlled clinical study of Buzhong Yiqi decoction combined with surgery in the treatment of rectal prolapse was performed from the establishment of databases to September 2020. Two investigators independently conducted data extraction and assessed the literature quality of the included studies. The Revman5.3 software was used for meta-analysis of the included literature. RESULTS: The efficacy and safety of Buzhong Yiqi decoction combined with surgery in the treatment of rectal prolapse were evaluated in terms of efficiency, symptom score, recurrence rate, adverse reaction rate, and so on. CONCLUSIONS: Thisstudy provides reliable evidence-based support for the clinical application of Buzhong Yiqi decoction combined with surgery in the treatment of rectal prolapse.
