Biliary Radiofrequency Ablation and Sphincterotomy Restenosis: A Unique Case of Biliary Obstruction.
Article in ACG case reports journal, 2025. 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
Biliary radiofrequency ablation is an emerging adjunctive and palliative therapy for patients with ampullary and biliary tumors. Given the high mortality for these malignancies, data on long-term complications are limited. We report a unique case of sphincterotomy restenosis causing biliary obstruction in a 98-year-old woman with a history of ampullary adenocarcinoma treated with papillectomy and biliary radiofrequency ablation (RFA). Endoscopic retrograde cholangiopancreatography revealed restenosis at the sphincterotomy site, managed successfully with repeat sphincterotomy and stenting. This case highlights sphincterotomy restenosis as a potential late complication of biliary RFA and emphasizes the need for awareness of delayed biliary obstruction in post-RFA patients.
