Superior Mesenteric Artery Syndrome Following Bariatric Surgery: A Systematic Review.
Synthesis in Obesity surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction caused by compression of the third part of the duodenum following loss of the mesenteric fat pad. This systematic review evaluated the frequency, diagnosis, management, and outcomes of SMA syndrome after Metabolic & Bariatric Surgery (MBS). A PRISMA-guided & PROSPERO registered search identified 11 studies reporting 20 cases, all in female patients, most commonly following Roux-en-Y gastric bypass. Diagnosis was confirmed with CT scan in most cases. Conservative management was successful in 15%, while 85% required surgical intervention, most frequently duodenojejunostomy. Overall symptom resolution occurred in 95%. In conclusion, SMA syndrome, although very rare, should be considered in MBS patients with refractory obstructive symptoms, with surgical management often required for definitive resolution.
