Combined approach for embolization of otherwise unmanageable gastric varices.
Article in Annals of gastroenterology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThis study aimed to determine the feasibility, safety and effectiveness of combined percutaneous transhepatic obliteration (PTO) and balloon-occluded retrograde transvenous obliteration (BRTO) therapy for the treatment of patients with high-risk bleeding gastric varices.
methodsTen patients were retrospectively reviewed. All the patients presented gastric varices, according to the Sarin classification, at high risk of bleeding, and not otherwise manageable. Patients with portal vein thrombosis were excluded. All patients were treated with a combination of PTO and BRTO. In all cases the gastric varices were embolized with glue, combined with coils or not, with an occlusion balloon inflated into the shunt. In 7 cases, embolization was immediate; in the remaining 3 the balloon remained inflated for 4 h and in 2 of them embolization of the shunt was required. Technical success was defined as complete obliteration of the gastric varices observed during a contrast-enhanced computed tomography study and endoscopy within 1 month following treatment. Clinical success was defined as absence of bleeding of gastric varices during the follow-up period. Major and minor complications during the follow up were recorded.
resultsTwelve sessions of combined PTO and BRTO procedures were performed in 10 patients; in 2 patients a new combined treatment was required during the follow up. Technical and clinical success was 100%. Neither major nor minor procedure-related complications were observed.
conclusionCombined PTO and BRTO therapy is safe and effective for the treatment of gastric varices that cannot be managed otherwise.
