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

There is no established treatment for bleeding bile duct varices (BDVs). We report the first case of portal vein (PV) stenting completely eradicating bleeding BDVs. A 70-year-old male with malignant lymphoma developed BDVs due to PV obstruction, which had caused compression and stricture of the distal bile duct. Endoscopic retrograde cholangiography was performed to evaluate the stricture and bleeding from the ruptured BDV was observed. Endoscopic hemostasis was difficult, requiring reopening of the extra-hepatic PV and reducing the blood flow to the BDVs for hemostasis. Therefore, PV stenting was performed. During the procedure, portal angiography confirmed an inflow tract to the BDVs. Therefore, covered stents were placed in the PV and adjusted to block the inflow tract to the BDVs at the distal end. After stenting, the BDVs were successfully blocked and all PV blood flowed through the stent placed in the extra-hepatic PV. Two weeks after stenting, the BDVs had disappeared completely and the bleeding has not recurred for months. We experienced a case in which PV stenting not only reopened an obstructed PV but also successfully occluded the inflow tract. This case demonstrates the potential of PV stenting for the treatment of hemorrhagic BDVs.
