Giant Type IV hiatal hernia with intrathoracic migration of abdominal viscera and atypical clinical presentation: a case report.
Article in Journal of 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
The Type IV paraesophageal hernia is the rarest and most treacherous hiatal hernia: herniated viscera compressing the chest cavity can imitate cardiopulmonary symptoms convincingly enough to derail the diagnostic workup. We describe a 57-year-old man in whom a Type IV hiatal hernia, which found incidentally 25 years earlier, had enlarged into a giant 15 × 12 cm defect with a 180-degree organoaxial gastric volvulus. He presented not with reflux but with orthopnoea, nocturnal cough, postprandial palpitations, and muffled heart sounds; only after a normal cardiac workup did computed tomography reveal stomach, colon, and small bowel within the thorax. Laparoscopic reduction, sac excision, cruroplasty, Nissen fundoplication, and mesh hiatoplasty resolved every symptom, with an intact repair confirmed at three years. This case captures the natural history of a neglected hernia and argues for early cross-sectional imaging when cardiopulmonary symptoms outlast a normal cardiac and pulmonary evaluation.
