Purpose: To evaluate the effect of different surgical methods in the treatment of high complex anal fistula by systematic review and network meta-analysis. Methods: Randomized controlled trials that met the inclusion criteria in PubMed, Cochrane Library, Embase, Web of Science, CBM, CNKI, WANFANG DATA, VIP were searched from the date of database construction to May 23, 2023. Results: Among the 48 randomized controlled trials (RCTs), 4205 patients were included in the network meta-analysis. Incision thread-drawing counter-drainage procedure (ITCP) in improving the effective rate, the cure rate; reduce the recurrence rate, reduce the anal canal damage has a huge advantage. Directional line-hanging method (DLM) is optimal for safety and postoperative pain relief. Directional line-hanging method (ITSS) protect the optimal anal function after surgery. Sphincter preserving thread-hanging method (SPTM) has a significant advantage in accelerating wound healing time. Main tube incision combined with thread-hanging branch tube drainage (MIBD) is second only to incision thread-drawing counter-drainage procedure (ITCP) in improving effective rate, cure rate, reducing recurrence rate and reduce complication rate. Conclusion: In general, different thread-drawing surgery methods have good clinical effect for the treatment of high complex anal fistula. In general, these methods provide evidence-based medical evidence for early treatment in terms of improving clinical efficacy, relieving anal pain and reducing wound healing time. However, there are differences in the number of included literature studies, and further verification by large-sample, high-quality, multicenter RCTS is still needed in the next stage.
