Robotic surgery for median arcuate ligament syndrome: technical aspects and imaging correlation.

backgroundMedian arcuate ligament syndrome (MALS) is an uncommon condition characterized by chronic and intermittent abdominal pain, typically postprandial, and weight loss, caused by extrinsic compression of the celiac trunk by the median arcuate ligament. The pathophysiology of the disease is not fully understood. Diagnosis is challenging due to nonspecific symptoms, and requires a careful correlation between clinical findings and imaging studies.

aimsTo demonstrate the feasibility, safety, and technical aspects of robotic median arcuate ligament release using a case-based approach with detailed imaging correlation.

methodsThe authors report the technical aspects in an elderly male patient with typical symptoms of MALS, who underwent robotic-assisted median arcuate ligament release using the da Vinci X platform. Preoperative evaluation included CT angiography and color Doppler ultrasound, demonstrating focal proximal celiac trunk stenosis.

resultsThe robotic approach allowed precise dissection and complete decompression of the celiac trunk without intraoperative complications. Postoperative imaging demonstrated resolution of the stenosis and normalization of Doppler flow parameters. The patient experienced complete symptom resolution, and remained asymptomatic after one year of follow-up.

conclusionsRobotic median arcuate ligament release is a safe and effective minimally invasive option, providing excellent visualization and precise dissection in a challenging anatomical region. This technique should be considered a valuable approach for selected patients with MALS. CENTRAL MESSAGE: Robotic surgery, due to the surgeon's ergonomics and the stability of the arms and instruments, wrist movement, and magnified threedimensional vision, allows for facilitated and safe access to the origin of the celiac artery as well as the dissection of fibrous tissues, innervation, and lymphatic vessels surrounding it. Given this, robotic surgery becomes feasible, effective, and safe for treating this syndrome, and it should be considered a preferred option in selected patients. PERSPECTIVES: The median arcuate ligament syndrome should be considered in cases of abdominal pain with no defined causes. A high index of suspicion can diagnose and treat more cases. Moreover, it is expected that robotic surgery will become increasingly accessible, allowing for an expansion of its indications.
