    Abstract:
    INTRODUCTION: Median arcuate ligament syndrome has been known anatomically for approximately 100 years and results from a compression of the coeliac axis by fibrous attachment of the diaphragmatic crura. Owing to the rarity of the disease and limited available data, many aspects of treatment are controversial. Currently, laparoscopic decompression is considered by several authors as standard surgical procedure. We present an analysis of the clinical routine of MALS therapy. METHODS: We conducted a prospective observational trial in patients with MALS between March 2016 and August 2018, in which clinical symptoms, diagnostic evaluation, procedures with complication analysis and follow-up data were recorded. RESULTS: A total of 18 patients (12 female, 6 male) with MALS, aged between 15 and 65 years, were included in this study. All patients presented with long-standing abdominal pain. Preoperative Doppler ultrasonography showed a flow velocity of the coeliac artery averaging 289.9cm/second in mid-position of the diaphragm, 285.9cm/second in expiration and 199.0cm/second in inspiration. All operated patients underwent laparoscopic decompression; two patients received an angiographic intervention. Postoperatively, a significant decrease of the flow velocity in mid-position of the diaphragm was detected (P = 0.018). At follow-up after 5.2 months, 50.0% of the patients were pain-free, 37.5% reported symptomatic relief and 12.5% showed evidence for a recurrence. CONCLUSION: MALS is challenging both diagnostically and therapeutically. Laparoscopy with release of the median arcuate ligament is an essential part of the therapy and can be confirmed by Doppler ultrasonography. Disease outcome is also influenced by several predictive factors.
