RESUMO
OBJECTIVE: To assess whether non-pharmacologic conservative therapeutic interventions are beneficial in improving pain intensity and quality of life in women with endometriosis compared with placebo. METHODS: A systematic review with meta-analysis was designed. A literature search was performed in the following databases: PubMed, PEDro, Embase, CINAHL, Isi Web of Science, Enfispo, and Cochrane. Randomized controlled trials included women with endometriosis treated with conservative treatment versus placebo. The quality of the studies was assessed using the PEDro scale, and the risk of bias of the individual studies was assessed using the Cochrane Risk of Bias tool. For the overall quality of the studies, the GRADE guidelines were used. RESULTS: Meta-analysis included six studies. Significant results were obtained for pain intensity (standardized mean difference [SMD] -0.89; 95% confidence interval [CI] -1.21 to -0.57; I2 69%) and concerning quality of life, significant results were only obtained for the sub-variable physical function (SMD -1.49; 95% CI -2.88 to -0.10; I2 95%). No statistically significant differences were found for the rest of the variables analyzed. CONCLUSION: Non-pharmacologic conservative therapies are a therapeutic option for women with endometriosis for improving pain intensity and physical function.
