The aim of this study is To investigate long-term symptom improvement and health-related quality of life (HRQOL) after operative intervention for median arcuate ligament syndrome (MALS). Clinical data of all consecutive patients treated by operative management of MALS from 1999 to 2018 were reviewed. A cross-sectional questionnaire using the Visick score, the Gastrointestinal Quality of Life Index, and Short Form (SF)-12v2 questionnaires was performed to assess long-term outcomes. The SF-12 HRQOL domains were compared between symptom-free and symptomatic patient groups and to averages for the US general population. Treatment failure was defined as no relief after surgery and Visick category 3 to 4 symptoms. Freedom from symptoms was estimated at 5 years.
The most common presenting symptom was abdominal pain in 99 patients with postprandial exacerbation in 85. One patient treated by laparoscopic release required conversion for an aortic injury, which was treated by primary repair and splenectomy. Forty-six patients responded to the questionnaire with a mean follow-up of 8 ± 4 years. Initial symptom resolution or improvement was reported by 38 patients (83%), whereas 8 patients (17%) reported treatment failure.
