This meta-analysis aims to compare the efficacy and economic impact of chemonucleolysis (CN) and discectomy in the management of LDH. An extensive search of Embase, PubMed, and Cochrane databases yielded 391 records. Following strict inclusion and exclusion criteria, twenty-one studies suitable for a comparative analysis between CN and discectomy were included. This selection was based on patient improvement, including pain scores, complications, and differences in cost and surgery time. A total of 2436 patients were included in this study. Among them, 1,121 patients (46%) underwent discectomy, while 1,315 patients (54%) received the CN approach. Our analysis revealed that discectomy had a significantly higher improvement rate compared with chymopapain CN (OR: 0.45; 95%CI 0.23,0.88) and non-chymopapain CN (OR: 0.61; 95%CI 0.38,0.97). A non-significant inclination towards complication rates was observed with chymopapain CN (OR: 1.90; 95%CI 0.68,5.29).
