Case Report: Endoscopic ultrasound in the diagnosis and endoscopic treatment of a delayed-presentation duodenal web in a toddler.

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
Duodenal web is rare in children, and reports of symptomatic cases with delayed presentation are even scarcer. This paper reports a 19-month-old female toddler admitted to hospital due to recurrent vomiting. Imaging examinations suggested duodenal obstruction, with an initial consideration of superior mesenteric artery syndrome or space-occupying lesion of the duodenum. In this case, circumferential thickening of the muscular layer of the duodenal wall was detected by endoscopic ultrasound (EUS), and pathological biopsy was performed simultaneously. Neoplastic lesions were systematically excluded, and the diagnosis of delayed-presentation duodenal web was established. The toddler successfully underwent endoscopic web incision eventually, avoiding open surgery. Postoperatively, the vomiting symptom was completely relieved without any complications. EUS clearly delineates the layered structure of the duodenal wall, thereby helping to elucidate the etiology of the obstruction and rule out neoplasms. This provides a direct basis for informed clinical decision-making regarding minimally invasive treatment of atypical, delayed-presentation duodenal obstruction.
