Percutaneous transhepatic treatment for biliary stricture after duct-to-duct biliary anastomosis in living donor liver transplantation: a 9-year single-center experience.
Article in European radiology, 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
objectivesTo investigate clinical outcomes of percutaneous transhepatic treatment for biliary stricture after duct-to-duct biliary anastomosis in living donor liver transplantation (LDLT).
methodsThis retrospective study examined baseline characteristics, procedural details, clinical outcomes, drainage catheter removal rate within 8 months, and recurrence after catheter removal using patients' medical records and images. Risk factors for failure of drainage catheter removal within 8 months and recurrence of biliary stricture after drainage catheter removal were assessed via univariable and multivariable analyses.
resultsA total of 112 patients (53.4 ± 8.79 years, 91 men) were evaluated. Multiple drainage catheters were placed in 75 patients (70.0%). Drainage catheters were successfully removed in 107 patients (95.5%). Failure of drainage catheter removal within 8 months was associated with hepatic artery complications (p = 0.034) and strictures requiring alternative passage techniques (p = 0.034). The cumulative primary patency rates after drainage catheter removal at 1, 2, 3, and 5 years were 85.4%, 79.8%, 75.8%, and 68.4%, respectively. Recurrence of biliary stricture was associated with the presence of an untreated isolated sectoral duct (aHR, 3.632; 95% CI, 1.086-12.150, p = 0.037) and with concurrent bile leaks (aHR, 2.475; 95% CI, 1.090-5.621, p = 0.031).
conclusionPercutaneous transhepatic treatment was effective for the treatment of biliary strictures after duct-to-duct biliary anastomosis in LDLT. Multiple drainage catheter maintenance was needed because multiple strictures often occurred in these patients. KEY POINTS: • Percutaneous transhepatic treatments are useful and effective for the treatment of biliary stricture after duct-to-duct biliary anastomosis in living donor liver transplantation (LDLT), although an endoscopic approach is available for this type of reconstruction. • Multiple drainage catheters were frequently placed in these patients because of multiple complex strictures. • We found that recurrence after drainage catheter removal was associated with isolation of the sectoral duct and with concurrent bile leaks.
