Background: Acupuncture and related therapies are effective and safe ways to relieve the pain, and improve the health and quality of life in women with endometriosis-related pain. However, it is still unclear which treatment is the most effective. Our study aims to summarize the evidence and determine the most effective and safe method to treat the endometriosis. Methods: We searched PubMed, EMBASE, Cochrane Library, and Web of science, China Biology Medicine, China National Knowledge Infrastructure, Wan fang Data, Chinese Scientific Journal Database and conducted manual searches of relevant papers, summarized randomized clinical trials of acupuncture-related therapies for endometriosis from database inception to 21 April 2024. After independent literature screening and data extraction that pain VAS was selected as the primary outcome measure. The quality evaluation was conducted by Review Manager 5.4. Perform network meta-analysis (NMA) used Stata 15.0 software. Results: Forty-two eligible trials involving six acupuncture-related interventions and 3,635 participants were included in this NMA. Pairwise meta-analyses show that combination therapy was more efficacious than western medicine and Chinese herb medicine for pain VAS scores, serum CA125 level and response rate results. The NMA estimates indicated that: for pain VAS scores, acupuncture (SMD: -2.33; 95% CI: -4.37, -0.29) and combination therapy (SMD: 1.79 95% CI: 1.21, 2.41) were superior to western medicine. For serum CA125 level, acupoint application (SMD: -11.33 95% CI: -20.28, -2.97) and combination therapy (SMD: 6.20; 95% CI: 1.60, 10.75) were associated with better efficacy when considered alongside western medicine. For response rate, combination therapy (SMD: 0.20; 95% CI: 0.14, 0.29) and auricular therapy (SMD: 8.01; 95% CI: 2.08, 45.37) were more efficacious than western medicine. The comprehensive ranking results show that acupoint catgut embedding was the best performing at lowering pain VAS scores, acupoint application was identified as the most effective in reducing serum CA125 level, and auricular therapy was ranked first in improving the response rate. Conclusion: Acupoint catgut embedding, auricular therapy, acupoint application and combination therapy may be the best solutions for the treatment of endometriosis. Additional trials are needed to develop higher-quality evidence and optimal regimens.
