Abstract

fetched live from OpenAlex

CASE REPORT A 59-year-old man with alcohol-related cirrhosis and a previously seen pancreatic mass presented with coffee-ground emesis accompanied by stable hemoglobin at 8.4 g/dL. Upper endoscopy with a standard gastroscope visualized blood in the duodenum without a source. Afterward, a side-viewing duodenoscope visualized a normal major papilla (Figure 1). Subsequently, active bleeding from the minor papilla was identified (Figure 2). Computed tomography angiography revealed a bilobed hematoma and peripancreatic pseudoaneurysm extending from the splenic artery (Figure 3). Coil embolization resulted in near-complete resolution of flow on repeat angiogram (Figure 4).Figure 1.: Side-viewing duodenoscope demonstrating the major papilla without bleeding (dotted blue circle).Figure 2.: Side-viewing duodenoscope revealing bleeding arising from the minor papilla (dotted blue circle).Figure 3.: Computed tomography angiography demonstrating a pseudoaneurysm originating from the splenic artery measuring 2.4 × 1.6 cm (red arrow).Figure 4.: Postembolization angiogram demonstrating resolution of flow through the proximal splenic artery (red arrow).Hemosuccus pancreaticus is a rare cause of upper gastrointestinal bleeding (1/1,500) defined by bleeding from the ampulla of Vater through the pancreatic duct and even more rarely emits from the minor papilla.1,2 Risk factors include chronic and recurrent acute pancreatitis, peripancreatic collections, and pancreatic malignancies.2 Clinical presentation often includes intermittent, repetitive hemorrhage, more frequently with melena than hematemesis.1 Endoscopy is crucial to rule out other causes of upper gastrointestinal bleeding and can infrequently identify hemorrhage from the duodenal ampulla, although angiography is the diagnostic gold standard with a 96% sensitivity.2 In hemodynamically stable patients, angioembolization is the preferred choice of therapy; although in cases of instability or failed embolization, patients should undergo hemostatic surgery.1–3 DISCLOSURES Author contributions: N.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
