Median Arcuate Ligament Syndrome (MALS) is a rare condition caused by external compression of the coeliac artery by the median arcuate ligament (MAL), leading to postprandial abdominal pain, nausea, vomiting, and weight loss. This study aims to compare outcomes of robotic (RMALR) and laparoscopic (LMALR) MAL release. A systematic search of PubMed/MEDLINE, Scopus, and Embase databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to compare perioperative and postoperative outcomes of LMALR versus RMALR. Comparative studies including adult patients undergoing either approach were included. Outcomes assessed were conversion to open surgery, resolution of pain, length of admission, postoperative complications, symptom recurrence and time to recurrence. Five retrospective comparative studies comprising 158 patients were included. No differences were found between laparoscopic and robotic approaches in conversion to open, resolution of pain, postoperative complications, length of admission, or overall time to recurrence. However, RMALR showed a significantly longer time to symptom recurrence (9.04 months, 95% CI 4.18-13.89; p = 0.0003). Both LMALR and RMALR are safe and effective for MALS, with comparable perioperative and postoperative outcomes. The longer symptom-free interval after robotic surgery may reflect greater precision in dissection around the coeliac axis. However, further prospective studies with standardised follow-up are needed to validate these findings.
