When acute cholecystitis is not what it seems: torsion of a free-floating gallbladder.
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
Free-floating gallbladder is a rare anatomic variant characterized by excessive mobility due to an elongated mesentery, predisposing it to torsion and vascular compromise. When torsion occurs, obstruction of the cystic duct and artery may rapidly progress to ischemia, necrosis, and gangrene, constituting a surgical emergency. Preoperative diagnosis is challenging because clinical, laboratory, and imaging findings often mimic uncomplicated acute cholecystitis. We report the case of an 87-year-old male with liver cirrhosis presenting with diffuse abdominal pain and elevated inflammatory markers. Ultrasonography and computed tomographic angiography were consistent with acute cholecystitis. However, laparoscopic exploration revealed a torsioned, necrotic, gangrenous free-floating gallbladder. Laparoscopic cholecystectomy was successfully performed, and recovery was uneventful. This case highlights the diagnostic limitations of imaging in rare anatomic variations and underscores the importance of early surgical intervention and intraoperative vigilance.
