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.

Background: Catgut-embedding therapy combined with minimally invasive surgery has been used for treating slow transit constipation (STC) widely. However, the application effect of catgut-embedding therapy combined with minimally invasive surgery for STC are unclear. This study aims to evaluate the application effect of catgut-embedding therapy combined with minimally invasive surgery for STC. Methods: Randomized controlled trials of catgut-embedding therapy combined with minimally invasive surgery in the treatment of STC will be searched in PubMed, EMbase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WanFang, the Chongqing VIP Chinese Science and Technology Periodical Database, and China biomedical literature database from inception to July, 2020. And Baidu Scholar, Google Scholar, International Clinical Trials Registry Platform, and Chinese Clinical Trials Registry will be searched to obtain more relevant studies comprehensively. Two researchers will perform data extraction and risk of bias assessment independently. Statistical analysis will be conducted in RevMan 5.3. Results: This study will summarize the present evidence by exploring the application effect of catgut-embedding therapy combined with minimally invasive surgery in the treatment of STC. Conclusions: The findings of the study will provide helpful evidence for the application effect of catgut-embedding therapy combined with minimally invasive surgery in the treatment of STC, facilitating clinical practice and further scientific studies. Ethics and dissemination: The private information from individuals will not publish. This systematic review also will not involve endangering participant rights. Ethical approval is not required. The results may be published in a peer-reviewed journal or disseminated in relevant conferences. OSF Registration number: DOI 10.17605/OSF.IO/7HVZB
