Duplicate gallbladder masquerading as a choledochal cyst: a case of single-port robotic surgery.
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
Gallbladder duplication is a rare congenital anomaly (1 in 4000 births) that can mimic other biliary pathologies, risking iatrogenic injury. A 61-year-old male presented with fever, right upper quadrant pain, and elevated aminotransferases. Contrast-enhanced computed tomography and magnetic resonance imaging initially suggested a 3.6-cm Todani type II choledochal cyst posterior to the gallbladder. Suspecting duplication, surgeons utilized a single-port robotic approach via the da Vinci SP system. Intraoperatively, two distinct gallbladders with independent cystic ducts were identified and successfully resected without complications. The operative time was 65 min, and histopathology confirmed chronic cholecystitis in both specimens. This case highlights the difficulty of differentiating gallbladder duplication from a type II choledochal cyst using cross-sectional imaging. Single-port robotic cholecystectomy offers enhanced visualization and articulating instrumentation, facilitating the safe, precise management of complex biliary anomalies.
