Abstract

Background: Postcholecystectomy syndrome (PCS) has become a common postoperative syndrome that requires systematic and comprehensive therapy to achieve adequate clinical control. Acupuncture and related therapies have shown clinical effects for PCS in many studies. However, systematic reviews/meta-analyses (SRs/MAs) for them are lacking.

Objective: To evaluate the efficacy and safety of acupuncture in the treatment of PCS using randomized controlled trials (RCTs).

Methods: Potentially eligible studies were searched in the following electronic databases up to 1 February 2020: PubMed, Embase, Cochrane Library, Web of Science (WoS), Chinese databases (Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), WanFang Database (WF), and China Science and Technology Journal Database (VIP)), and other sources (WHO ICTRP, ChiCTR, Clinical Trials, and Grey Literature Database). The RevMan 5.3 was employed for analyses. The Cochrane Collaboration' risk of bias tool was used to assess the risk of bias (ROB). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach was used to assess the quality of the evidence.

Results: A total of 14 RCTs with 1593 participants were included in this SR. MA showed that acupuncture in combination with conventional medicine (CM) did not show statistical differences in reduction in pain. However, acupuncture in combination with CM significantly reduced the incidence of postoperative nausea and vomiting (PONV) (RR, 0.71; 95% CI, 0.55-0.92) and improved gastrointestinal function recovery compared to the CM group. Acupuncture combined with traditional Chinese medicine and CM, and acupuncture as monotherapy may improve gastrointestinal function recovery with acceptable adverse events.

Conclusion: Acupuncture may be an effective and safe treatment for PCS. However, this study lacks conclusive evidence due to poor quality evidence, limited data, and clinical heterogeneity of acupuncture methods in the included studies.
