Congenital intrinsic proximal jejunal obstruction caused by a mucosal web near the duodenojejunal junction in a neonate: a case report and literature review.

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
Congenital intrinsic obstruction at or near the duodenojejunal junction is exceptionally rare and most commonly results from incomplete embryonic recanalization, leading to the formation of a mucosal web. We report a 7-day-old term male neonate (birth weight 3350 g) who presented with persistent feeding intolerance and intermittent bilious vomiting since birth. Abdominal radiography showed marked dilation of the stomach and duodenum with distal bowel gas. An upper gastrointestinal contrast study revealed a conical narrowing at the duodenojejunal junction. Surgical exploration revealed a mucosal web located immediately distal to the duodenojejunal junction. Given the marked luminal disparity, simple web excision was deemed inadequate, and segmental resection with primary end-to-end jejunojejunal anastomosis was performed. Postoperative recovery was uneventful. Proximal jejunal webs near the duodenojejunal junction are rare but surgically correctable causes of neonatal bilious vomiting and should be considered in the differential diagnosis.
