Does coil deployment improve outcomes in GOV1 gastroesophageal varices? A retrospective case-control study.
Article in Surgical endoscopy, 2026. 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
objectivesEndoscopic ultrasound (EUS)-guided coil deployment is widely used for fundal gastric varices and is associated with a higher variceal obliteration rate and reduced cyanoacrylate volume. However, its benefit in type 1 gastroesophageal varices (GOV1) remains unclear. This study aimed to evaluate whether deploying coil has privilege in GOV1 gastroesophageal varices.
methodsBased on retrospectively collected data, cirrhotic patients receiving EUS-guided coil and cyanoacrylate injection for GOV1 varices were enrolled in the case group, and patients treated with cyanoacrylate injection under straight-view endoscopy comprised the control group. Variceal obliteration rate, cyanoacrylate glue volume, rebleeding rate, and other clinical outcomes were compared between the two groups.
resultsA total of 42 patients with GOV1 varices were enrolled in the final analysis (21 patients in the case group and 21 in the control group). The complete variceal obliteration rate was 100.0% in the case group and 55.0% in the control group. Less cyanoacrylate glue was required in the case group than in the controls (1.67 mL vs. 2.52 mL, p < 0.01). The case group showed a trend toward a lower 3-month rebleeding rate than the control group, with no significant difference (4.8% vs. 28.6%, p = 0.093).
conclusionsDeployment of coils under EUS guidance appears to be beneficial in patients with GOV1 varices.
