Transhepatic stent placement for portal vein obstruction after hepatobiliary and pancreatic surgery: long-term efficacy and risk factor for stent failure.
Article in European radiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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 evaluate the long-term efficacy of transhepatic portal vein (PV) stent placement in patients with postoperative PV obstruction and to identify risk factors for stent failure.
methodsBetween January 2007 and October 2019, percutaneous transhepatic PV stent placement was attempted in 60 patients with postoperative PV obstruction. Technical and clinical success, complications, and stent patency were retrospectively evaluated. Thirteen clinical variables were analyzed to determine risk factors for stent failure.
resultsStent placement was technically successful in all patients. Thromboaspiration (n = 19) and jejunal variceal embolization (n = 7) were performed in the same session. Clinical symptoms related to portal hypertension were resolved in 54 patients (90.0%). There was no procedure-related complication. During the follow-up period (mean 630 days), stent failure occurred in 13 patients. One- and 5-year stent patency rate was 74.8% and 64.9%, respectively. The presence of a pancreatic fistula was the only independent risk factor associated with stent failure (HR 7.54; 95% CI 2.02-28.10, p = 0.003).
conclusionsPercutaneous transhepatic PV stent placement is a technically feasible and effective treatment for postoperative PV obstruction. The pancreatic fistula is a risk factor for stent failure. KEY POINTS: • Percutaneous transhepatic stent placement is an effective treatment to improve portal hypertension-related symptoms in patients with portal vein obstruction after hepatobiliary and pancreatic surgery. • The pancreatic fistula is an independent risk factor for portal vein stent failure.
