Superior Mesenteric Artery Syndrome After Previous Nuss Procedure: A Case Report of Anatomical Realignment With Unintended Consequences.

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
Background: Superior mesenteric artery (SMA) syndrome is a rare condition resulting from compression of the third segment of the duodenum. The condition is associated with a reduction of the aortomesenteric angle and distance between the SMA and the abdominal aorta, often due to weight loss or anatomical changes. The Nuss procedure, a minimally invasive corrective procedure for pectus excavatum, may inadvertently alter this anatomy. Case Presentation: We report a case of a 22-year-old male with a history of pectus excavatum who presented with two weeks of abdominal pain and vomiting. Abdominal A CT scan and esophagogastroduodenoscopy examinations were performed, revealing duodenal compression with a narrowed aortomesenteric distance of 6 mm, which is consistent with SMA syndrome. The patient then underwent laparoscopic duodenojejunostomy anastomosis bypass after failed conservative management with complete symptom resolution. Conclusion: Clinicians should be aware of the potential development of SMA syndrome in patients following the Nuss procedure. Monitoring nutritional status and prompt evaluation of gastrointestinal symptoms are essential to early diagnosis and intervention.
