Benign Portal Vein Stenosis After Pancreaticoduodenectomy.
Article in World journal of surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 19 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
backgroundThe long-term patency of the portal vein (PV) in patients who survive after pancreaticoduodenectomy (PD) remains unclear. The aim of the present study was to investigate the clinical features and risk factors for benign PV stenosis after PD.
methodsWe retrospectively analyzed the patients who underwent PD from September 2002 and December 2015 at our institution without intraoperative radiation therapy or concomitant PV resection. The postoperative computed tomography of each patient was evaluated, and PV stenosis was defined as the shortest diameter of the PV being <3 mm. The patients with PV stenosis due to local recurrence were excluded.
resultsOf the 458 patients, PV stenosis occurred in 57 (12.4%), including benign PV stenosis in 28 (6.1%) and PV stenosis due to local recurrence in 29 (6.3%). Of the 28 patients with benign PV stenosis, 7 (25%) developed symptoms related to portal hypertension, namely recurrent gastrointestinal bleeding in 5 and refractory ascites in 2. Six patients were treated with percutaneous transhepatic PV stent placement, and all of their symptoms improved. A multivariate analysis found that a postoperative pancreatic fistula was an independent risk factor for benign PV stenosis after PD (odds ratio, 4.36; p = 0.005).
conclusionsPostoperative pancreatic fistula was a significant risk factor for benign PV stenosis after PD. Stent placement for benign PV stenosis was effective for the patients with symptoms due to portal hypertension.
