A gastric dieulafoy lesion presenting with life-threatening upper gastrointestinal hemorrhage during recovery from hypertriglyceridemic acute pancreatitis: a case report.
Article in Frontiers in medicine, 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
Background: Dieulafoy lesions are an uncommon but potentially life-threatening cause of non-variceal upper gastrointestinal bleeding, caused by rupture of a large-caliber submucosal artery through a minute mucosal defect; diagnosis is difficult because bleeding is intermittent and the surrounding mucosa appears nearly normal. Hemorrhage from a gastric Dieulafoy lesion during recovery from hypertriglyceridemic acute pancreatitis (HTG-AP) has rarely been reported. Case presentation: A man in his twenties with severe obesity presented with acute epigastric pain after alcohol and a high-fat meal. Serum triglycerides were 53.67 mmol/L (reference 0.56-1.70), and CT confirmed acute pancreatitis. Because of extreme hypertriglyceridemia and evolving organ dysfunction, he received intensive lipid-lowering therapy, plasma exchange, continuous renal replacement therapy, and supportive care in the ICU, and improved. During recovery he developed sudden massive hematemesis with tachycardia, hypotension, and a fall in hemoglobin to 65.9 g/L. Emergency endoscopy showed extensive intragastric clots and could not locate the source. After stabilization, repeat endoscopy revealed an isolated thrombus-like protrusion with active oozing on the lesser curvature near the cardia, with otherwise normal mucosa, consistent with a Dieulafoy lesion; three metallic clips achieved immediate hemostasis. Contrast-enhanced CT excluded pseudoaneurysm, splenic-vein thrombosis, gastric varices, and other pancreatitis-related vascular complications. No recurrence occurred during hospitalization or approximately seven months of follow-up, with healed mucosa on later endoscopy. Conclusion: A gastric Dieulafoy lesion is a rare but life-threatening cause of bleeding during recovery from HTG-AP. A nondiagnostic first endoscopy because of clot retention does not exclude it, and persistent bleeding warrants repeat endoscopy after stabilization and gastric clearance. Bleeding should not be attributed solely to stress injury or anticoagulation; an underlying structural lesion should be sought. Clipping achieved durable hemostasis in this patient, but a single case cannot establish comparative efficacy.
