Hybrid intervention with angio-CT for percutaneous transhepatic biliary drainage (PTBD).
Article in Abdominal radiology (New York), 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
purposeTo evaluate a hybrid angiography-CT (angio-CT) system for percutaneous transhepatic biliary drainage (PTBD) in patients with biliodigestive anastomosis, aerobilia, and the need for external biliary drainage. MATERIALS AND
methodsTen patients with bile duct leakage and aerobilia underwent angio-CT-guided PTBD. The angio-CT enabled combined CT and fluoroscopic imaging in a single procedural setting. Aerobilia facilitated bile duct visualization, particularly in left-sided ducts. Key steps included CT-guided puncture, fluoroscopic catheter placement, and integration of both modalities to streamline workflow.
resultsSuccessful biliary access and drainage were achieved in all cases. The combined imaging approach allowed for short intervention times (mean: 25 min) and ensured safety without complications. Aerobilia, improved visualization and precision were key contributors to the technique's success.
conclusionAngio-CT may improve procedural precision and safety when aerobilia is present.The integration of CT and angiography within a single system offers a reliable solution for challenging biliary interventions. Larger studies are needed to confirm these findings.
