Abstract
PURPOSE: To carry out a systematic review and meta-analysis of the efficacy of chemonucleolysis in the treatment of lumbar disc herniation. METHODS: Clinical trials were selected from 3 electronic databases (The Cochrane Controlled Trials Register, MEDLINE, and EMBASE). Data were analyzed with the software STATA, using the meta command. RESULTS: Twenty-two clinical trials were eligible. For chemonucleolysis versus placebo, the summary risk ratio estimate for pain relief as outcome was 1.51 (95% CI: 1.27-1.80). The summary estimate was 1.07 (95% CI: 0.95-1.20) for the comparison between chymopapain and collagenase. Regarding chemonucleolysis with chymopapain versus surgery, the fixed-effect summary estimate of effect for pain relief was 0.93 (95% CI: 0.88-0.98) with surgery as the reference group. In this case, heterogeneity was statistically significant. CONCLUSIONS: Chemonucleolysis with chymopapain was superior to placebo and was as effective as collagenase in the treatment of lumbar disc prolapse. Results for studies comparing chemonucleolysis with surgery were heterogeneous, making it difficult to interpret the summary measure of effect.
OBJETIVO: Avaliar a eficácia da quimonucleólise no tratamento da hérnia de disco lombar por meio de uma metanálise de ensaios clínicos. MÉTODOS: Os ensaios clínicos foram selecionados de três bases de dados eletrônicas( Cochrane, MEDLINE, e EMBASE). Os dados foram analisados por intermédio do aplicativo STATA, com o comando meta. RESULTADOS: trabalhamos com 22 ensaios clínicos. Para a comparação entre quimonucleólise e placebo, a estimativa da razão de riscos, tendo melhora da dor como desfecho, foi de 1,51 (I 95% C: 1,27-1,80). Aquela medida foi de 1,07 (I 95% C: 0,95-1,20) para a comparação entre quimopapaína e colagenase. Em um modelo de efeitos fixos, a razão de risco, para melhora da dor, foi 0,93 (I 95% C: 0,88-0,98), tendo a discectomia como grupo de referência. Nesse caso, um teste de heterogeneidade foi considerado estatisticamente significante. CONCLUSÕES: a eficácia da quimonucleólise foi superior à do placebo e semelhante à da colagenase. Os resultados dos estudos referentes à comparação entre quimonucleólise e cirurgia foram heterogêneos, o que implica interpretação não-trivial da medida de efeito.
