Introduction: Previous reviews have suggested that the effectiveness of acupuncture for inflammatory bowel disease (IBD) has not well been demonstrated due to the limited randomised controlled trials (RCTs). In recent years, the growing research on acupuncture for IBD make it possible to conduct a further systematic review and synthesise more sufficient clinical data to evaluate the effectiveness and safety of acupuncture for IBD.
Methods and analysis: Nine electronic databases without language restriction will be retrieved from inception to March 2021, including the Cochrane Library, MEDLINE, EMBASE, Ovid, the Allied and Complementary Medicine Database, China National Knowledge Infrastructure, Chinese Biomedical Literature Database, the Chongqing Chinese Science and Technology Periodical Database and Wanfang Database. The RCTs on acupuncture for IBD will be included. The data screening, data extraction and the assessment of risk bias will be performed respectively by two reviewers. The quality of evidence will be evaluated by using the Grading of recommendation Assessment, Development and Evaluation application. The meta-analysis will be performed if heterogeneity analysis conducted on the RevMan software (V.5.3) is insignificant. The primary outcome was symptoms alleviation after acupuncture treatment or even in the follow-up.
Ethics and dissemination: Ethical approval will not be needed because data of this review are not involved in patient's information and privacy. The results will be published and diffused in a peer-reviewed journal or relative conferences.
Trial registration number: CRD42020157903.
