A systematic review on the efficacy of treatment of the Median Arcuate Ligament Syndrome.

This systematic review suggests a sustainable symptom relief above 70% after treatment for MALS in the majority of the adult and paediatric studies but due to the heterogenicity of the inclusion criteria and outcome parameters the risk of bias is high and a formal meta-analysis cannot be performed. To improve care for patients with MALS the next steps would be to deal with reporting standards, outcome definitions and consensus descriptions of the intervention(s) after which an appropriate randomized controlled trial can be performed.
