Factors Affecting Clinical Course of Postoperative Bile Leakage and Efficacy of Endoscopic Biliary Drainage: A Multi-Center Retrospective Cohort Study.

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
Introduction: Bile leakage is one of the complications after hepatobiliary surgery, causing intra-abdominal infections, and is sometimes difficult to treat. The purpose of our study was to investigate the factors related to severity and to evaluate the efficacy of endoscopic treatment. Methods: This was a retrospective multicenter cohort study conducted at three tertiary care medical centers. The severity of bile leakage was classified per the International Study Group of Liver Surgery, and Grades B and C (requiring some intervention or reoperation) were considered as severe. Results: The subjects were 59 patients. The surgical procedures were 31 cholecystectomies, 23 hepatectomies, and five pancreaticoduodenectomies. The severity was Grade A/B/C: 17/40/2. Multivariate logistic regression analysis found that age (unit odds ratio [UOR], 1.09; 95% confidence interval [CI], 1.0-1.19; Conclusion: In the management of bile leakage after hepatobiliary surgery, elderly patients or patients with late onset of bile leak may be at high risk of severity. Endoscopic biliary drainage is considered a safe and effective treatment for severe patients.
