Efficacy and Safety of Percutaneous Transhepatic Cholangioscopy with the Spyglass DS Direct Visualization System in Patients with Surgically Altered Anatomy: A Pilot Study.
Article in Gut and liver, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 18 papers, 1 of them a synthesis that pooled it.
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/
aims: Percutaneous transhepatic cholangioscopy (PTCS) is used for the diagnosis and treatment of biliary diseases in patients with failed endoscopic retrograde cholangiopancreatography, particularly those with surgically altered anatomy. However, few studies are available on the clinical use of Spyglass DS direct visualization system (SpyDS)-assisted PTCS. This study aimed to assess the efficacy and safety of SpyDS-assisted PTCS in patients with surgically altered anatomy, particularly those with a Roux-en-Y reconstruction.
methodsThirteen patients (six women, median age 71.4 years [range, 53 to 83 years]) with surgically altered anatomy (four Roux-en-Y choledochojejunostomies, seven Roux-en-Y hepaticojejunostomies, and two Roux-en-Y esophagojejunostomies) who underwent SpyDS-assisted PTCS between January 2019 and August 2020 were included and the data was acquired by retrospectively reviewing electronic medical record.
resultsA total of 19 SpyDS-assisted PTCS procedures were performed in the 13 patients: eight had bile-duct stones, and five had biliary strictures. All SpyDS-assisted PTCS procedures were successfully performed. The total procedure time was 42.42±18.0 minutes (mean±standard deviation). Bile duct clearance was achieved in all bile duct stone cases after a median of 2 (range, 1 to 3) procedures. In the five biliary stricture cases, the results of SpyBite forceps-guided targeted biopsy were consistent with adenocarcinoma (100% accuracy). The median hospitalization duration was 20 days (range, 14 to 30 days). No procedure-related morbidity or mortality occurred.
conclusionsSpyDS-assisted PTCS may be a safe, feasible, and effective procedure for the diagnosis and treatment of biliary diseases in patients with surgically altered anatomy, particularly in those with the Roux-en-Y reconstruction requiring a percutaneous approach. However, our findings need to be validated in further studies.
