Endoscopic bilateral revision after metal stent deployment for hepatic hilar obstruction using molting technique (with videos).
Article in Therapeutic advances in gastroenterology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: After multiple uncovered self-expandable metal stent (UCSEMS) deployments, endoscopic revision becomes complex and potentially challenging. A novel stent delivery system with a dilation function has recently been developed in Japan. This study evaluated the technical feasibility of this device for patients with unresectable malignant hilar biliary obstruction (MHO) after multiple UCSEMS deployments. Method: Participants comprised consecutive patients with unresectable MHO who had undergone multiple UCSEMS deployments and required endoscopic revision for the right or left hepatic bile ducts, as decided by cholangiography under endoscopic retrograde cholangiopancreatography (ERCP) guidance. Results: A total of 14 patients requiring endoscopic revision of right and left hepatic bile ducts were enrolled in this study. Among these 14 patients, guidewire insertion through the mesh of previously placed stents failed in 2 patients. As a result, these two patients underwent only unilateral UCSEMS deployment. Because clinical success was not obtained, transmural placement of the UCSEMS under Endoscopic Ultrasound (EUS) guidance to the segment of the liver not being drained was performed in those patients. The molting technique was attempted in 12 patients, proving successful in all patients. The technical success rate was therefore 92.8% (12/14). Mean procedure time was 23.2 min. Conclusion: This novel stent delivery system with a dilation function may be useful in endoscopic revision techniques for bilateral UCSEMS deployment.
