Internal Hernia Through the Pars Flaccida: A Rare Intraoperative Finding.
Article in The American journal of 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
BACKGROUND Internal hernias through the pars flaccida of the lesser omentum are rare variants that pose unique diagnostic and therapeutic challenges, representing less than 1% of all internal hernias. Diagnosis is particularly challenging due to their nonspecific presentation and subtle radiological features. CASE REPORT We present a case of successful laparoscopic repair of a pars flaccida internal hernia in a 52-year-old woman with complex surgical history, including previous colorectal cancer surgery. We detail our systematic surgical approach and conducted a comprehensive literature review of laparoscopically managed pars flaccida hernias using the PubMed database. The patient presented with recurrent episodes of epigastric pain and nausea. Diagnostic laparoscopy revealed herniation of the small bowel through the pars flaccida anterior to the stomach, along with a secondary mesenteric defect. Both defects were successfully repaired laparoscopically using non-absorbable sutures. Key technical elements included strategic 5-port placement, systematic adhesiolysis, and meticulous reduction of the herniated bowel. The patient's symptoms resolved after repair. CONCLUSIONS Laparoscopic repair of pars flaccida hernias is feasible with appropriate technical expertise. Success depends on careful preoperative planning, strategic port placement, and thorough inspection for additional defects. This case highlights the importance of considering internal hernias in patients with intermittent abdominal pain following previous surgery, even when initial imaging is inconclusive.
