Outcomes of surgical versus conservative treatment in pediatric median arcuate ligament syndrome.
Article in Journal of pediatric gastroenterology and nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesMedian arcuate ligament syndrome (MALS) involves compression of the celiac artery and presents with gastrointestinal symptoms. We evaluated outcomes after surgical versus conservative management in pediatric MALS.
methodsWe reviewed charts of symptomatic patients aged 7-21 years diagnosed by ultrasound and/or computed tomography angiogram. Outcomes were categorized as resolved, improved, unchanged, or worsened at most recent follow-up and compared between conservative and surgical treatment groups.
resultsAmong 34 patients (median age 15 years, 79% female, 94% Caucasian), common symptoms included abdominal pain (85%) and nausea (71%); 36% had psychiatric disorders, 56% met criteria for disorders of gut-brain interaction (DGBI). Ten received conservative therapy (100% pharmacologic, 80% behavioral, 30% botulinum toxin, 20% neurostimulation) with a median follow-up of 5 months. Outcomes were resolution (20%), improvement (40%), unchanged (40%), and none worsened. Of 24 surgical patients (median hospital stays: 4 days), outcomes were: resolution (21%), improved (33%), unchanged (17%), worsened (29%); not significantly different from conservative group (p = 0.21). Postoperative complications occurred in 21%. At median 20-day postoperative follow-up, 52% reported resolution, 35% improved, 9% unchanged, 4% worsened. Pain location differed by group (p = 0.005); other demographics and long-term outcomes did not (p > 0.05). Baseline comorbidities and treatment modalities were not significantly associated with outcome (p > 0.05).
conclusionIn our cohort, 60% of children with MALS improved with conservative DGBI-directed therapy and 54% improved with decompression surgery at long-term follow-up, despite a robust short-term postoperative response (87%). Prospective studies are needed to guide patient selection and assess long-term outcomes.
