1 · What the graph read from 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.

2 · The registry

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

Ectopic varices bleeding around the choledochojejunostomy site, potentially caused by portal vein occlusion, is a rare complication following pancreatoduodenectomy. In this report, we present a case of ectopic varices around the choledochojejunostomy site after pancreatoduodenectomy. A 55-year-old man who underwent pancreatoduodenectomy with portal vein reconstruction for pancreatic ductal adenocarcinoma suffered from hematochezia. Contrast-enhanced computed tomography revealed total occlusion of the main portal vein and ectopic varices around the choledochojejunostomy anastomosis site. An attempt at endoscopic hemostasis using clipping was unsuccessful. Consequently, a main portal vein stent was inserted to eliminate the varices. We successfully restored blood flow in the portal vein and eradicated the varices. Additionally, endoscopic changes were directly visualized using double-balloon endoscopy. Therefore, portal vein stent placement may be an effective treatment option for ectopic variceal bleeding around the choledochojejunostomy site following pancreatoduodenectomy.
