Preoperative Suspicion of Internal Hernia and Laparoscopic Repair of a Congenital Transmesocolic Hernia Presenting as Closed-Loop Small-Bowel Obstruction: A Case Report.
Article in Surgical case reports, 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
introductionTransmesocolic hernia is a rare cause of small-bowel obstruction, and preoperative diagnosis remains difficult because of nonspecific clinical and radiologic findings. CASE PRESENTATION: A 69-year-old woman presented with abdominal pain and vomiting. Contrast-enhanced CT demonstrated a closed-loop small-bowel obstruction adjacent to the ligament of Treitz, raising suspicion of an internal hernia. Emergency laparoscopic exploration revealed incarceration of a 12-cm segment of jejunum through a transverse mesocolic defect. The bowel was successfully reduced laparoscopically without resection, and the defect was closed using a continuous barbed suture. Direct laparoscopic inspection demonstrated no communication between the defect and the lesser sac, suggesting that the incarcerated bowel remained confined within the transverse mesocolon. The postoperative course was uneventful, and the patient was discharged on POD 8.
conclusionsThis case highlights the value of early laparoscopic intervention for transmesocolic hernia and provides additional insight into the anatomical variability of transverse transmesocolic hernias.
