Performing median arcuate ligament release surgery in celiac artery compression syndrome: Insights from a tertiary care hospital.

Abstract

Median arcuate ligament syndrome (MALS), also known as Dunbar syndrome or celiac artery (CA) compression syndrome, is a rare condition characterized by persistent post-meal or post-exercise abdominal discomfort, often more pronounced during expiration. Additional symptoms include nausea, vomiting, and weight loss. To document the clinical presentation, diagnostic process, and treatment outcomes of seven patients diagnosed with MALS and to evaluate the effectiveness of surgical release of the median arcuate ligament (MAL) over a follow-up period of at least six months. The study included seven patients diagnosed with MALS from 2019 to 2021. Diagnosis was based on the presence of chronic abdominal pain and associated symptoms, absence of alternative diagnoses after various clinical assessments, and angiographic evidence of CA compression. The primary treatment involved surgical decompression of the CA by releasing the MAL through either open or laparoscopic techniques. All seven patients underwent successful surgical release of the MAL. The patients were followed up for at least six months post-surgery. The study evaluated the persistence of symptoms and the need for additional interventions such as revascularization techniques. Surgical release of the MAL is the primary treatment for MALS, providing relief for many patients. However, long-term follow-up is essential as some patients may continue to experience symptoms post-surgery, necessitating further interventions.
