A nationwide analysis of median arcuate ligament release between 2010 and 2020: a NSQIP Study.

Abstract

BackgroundMedian arcuate ligament syndrome is a rare disease with overlapping symptoms of broad foregut pathology. Appropriately selected patients can benefit from a laparoscopic or open median arcuate ligament release. Institutional series have reported the outcomes of open and laparoscopic techniques but there are no nationwide analysis comparing both techniques and overall trends in treatment.MethodsCross-sectional study using the American College of Surgeons-National Surgical Quality Improvement Project from 2010 to 2020. Celiac artery compression syndrome cases were identified by International Classification of Diseases (ICD) codes and categorized as open or laparoscopic. Trends in the use of each technique and 30-day complications were compared between the groups.ResultsA total of 578 open cases (76%) and 185 laparoscopic cases (24%) were identified. There was an increase adoption of the laparoscopic approach, with 22% of the cases employing this technique at the end of the study period, compared to 7% at the beginning of the study period. The open group had a higher prevalence of hypertension (26% vs 18%, p = 0.04) and bleeding disorders (5% vs 2%, p 0.03). Laparoscopic approach had a shorter length of stay (2.3 days vs 5.2 days, p < 0.0001), lower major complication rates (0.5% vs 4.0%, p = 0.02) and lower reoperation rates (0% vs 2.6%, p = 0.03). Overall mortality was 0.1%.ConclusionOverall numbers of surgical intervention for treatment of median arcuate ligament increased during this timeframe, as well as increased utilization of the laparoscopic approach. It appears to be an overall safe procedure, offering lower rates of complications and shorter length of stay.
