Cholangioscopy with Spyglass DS using percutaneous transhepatic cholangiography access: a retrospective cohort study.
Article in Annals of medicine and surgery (2012), 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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: Conventional peroral methods to visualize biliary strictures are not feasible in some patients with altered anatomy or biliary obstruction, and percutaneous transhepatic cholangioscopy can be used as an alternative procedure. This study aimed to retrospectively review the use of percutaneous transhepatic cholangiography using the SpyGlass DS technology (S-PTCS) during a 5-year period at a Danish tertiary referral centre. Materials and methods: All patients who underwent S-PTCS at a single Danish tertiary referral centre between 2016 and 2021 were retrospectively analyzed. The visual, technical, and overall success rates of S-PTCS were analyzed, as well as the complication rate. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of S-PTCS were calculated. Results: Twenty-two patients were included in the study. Visual, technical, and overall success of S-PTCS was achieved in 17/22, 22/22, and 21/22 patients, respectively. S-PTCS yielded a sensitivity of 83.3%, a specificity of 100%, a PPV of 100%, a NPV of 94.1%, and an accuracy of 95.4%. Complications occurred in 1/22 patients. Conclusion: S-PTCS is a safe modality, with high success rates, high predictive values, and a low rate of complications. This study suggests that S-PTCS is an alternative to conventional methods in patients with indeterminate biliary strictures where conventional methods were unfeasible.
