Purpose. The aim of the research was to evaluate the efficacy and safety associated with Fuke Qianjin tablet combined with conventional therapy in the treatment of pelvic inflammatory diseases and associated complications (endometritis) using a meta-analysis approach. Patients and Methods. We searched 8 electronic databases up to December 31, 2019, including PubMed, the Cochrane Library, Embase, Web of Science, CNKI, WanFang, VIP, and SinoMed. Eligible studies were clinical trials of Fuke Qianjin tablet combined with conventional therapy used in the treatment of acute pelvic inflammatory disease, chronic pelvic inflammatory disease, and endometritis. The meta-analysis was performed using STATA15 software. Results. A total of 125 RCTs (n = 14,494) were shortlisted for the meta-analysis, which included 23 trials for acute pelvic inflammatory disease, 69 trials for chronic pelvic inflammatory disease, and 33 trials for endometritis. The overall analysis illustrated Fuke Qianjin tablet combined with conventional therapy was significantly more efficacious than conventional therapy alone across all types of antibiotics treatment for acute pelvic inflammatory disease (OR = 5.57, 95% CI 4.09–7.58, Z = 10.90, p = 0.001 ), chronic pelvic inflammatory disease (OR = 4.70, 95% CI 4.07–5.42, Z = 21.21, p = 0.001 ) and endometritis (OR = 5.09, 95% CI 4.03–6.43; Z = 13.63, p = 0.001 ) in both primary endpoints and secondary endpoints. There is also a trend that Fuke Qianjin tablet combined with conventional therapy has lower adverse reaction rates than conventional therapy alone. Conclusion. Fuke Qianjin tablet combined with conventional therapy showed better clinical efficacy in the treatment of acute pelvic inflammatory disease, chronic pelvic inflammatory disease, and endometritis. There were no obvious drug-related adverse reactions. Fuke Qianjin tablet presented advantages in shortening the remission time of clinical symptoms, reducing the concentration of serum inflammatory factors, improving endometrial thickness, menstruation, and reducing relapse rate.
