Strangulated transomental hernia causing small bowel obstruction in a virgin abdomen.

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
Transomental hernia is a rare cause of small bowel obstruction and may be missed before surgery, particularly in a virgin abdomen. We report a 75-year-old woman with no previous abdominal operation who presented with 4 days of abdominal pain, vomiting, distension, constipation, and reduced urine output. She had leukocytosis and acute kidney injury. Because of renal dysfunction, computed tomography was performed without intravenous contrast. It showed dilated ileal loops, a pelvic transition point, mild ascites, and twisting of mesenteric vessels at the transition point, suggestive of volvulus or closed-loop obstruction. Internal hernia was not diagnosed preoperatively. Emergency laparotomy revealed ileum strangulated through a 3 cm greater omental defect. Approximately 120 cm of gangrenous ileum was resected, the defect was excised, and single-layer extramucosal hand-sewn end-to-end anastomosis was performed. The case emphasizes that closed-loop obstruction in a virgin abdomen should prompt early consideration of internal hernia.
