Hemostatic Hold-Up: A Rare Case of Endoscopic Retention After Hemostatic Powder Application.
Article in ACG case reports journal, 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
Hemospray (TC-325), a powder-based hemostatic spray, is increasingly used for upper gastrointestinal bleeding but can rarely cause endoscope retention. A 74-year-old woman with chronic kidney disease, atrial fibrillation on warfarin, mechanical heart valves, and prior gastric ulcers presented with melena and large-volume hematemesis causing hemodynamic instability. Laboratory findings revealed hemoglobin 7.3 g/dL and international normalized ratio 7. Esophagogastroduodenoscopy showed multiple bleeding arteriovenous malformations in the cardia and fundus, treated with a synthetic self-assembling peptide gel and subsequently with hemospray applied in retroflexion. Withdrawal of the endoscope was initially unsuccessful due to powder adhesion, but aggressive water irrigation enabled removal after 90 minutes. The patient stabilized with transfusions and octreotide, with no recurrent bleeding. This case underscores the risk of endoscope retention when Hemospray is applied retroflexed and suggests aggressive irrigation as a potential remedy. Further studies are needed to optimize Hemospray dosing and evaluate self-assembling peptide-powder interactions.
