Abstract
Non-variceal upper-gastrointestinal bleeding (NVUGIB) refractory to therapeutic endoscopy is a challenging situation. The following details a novel use for the Sengstaken-Blakemore tube in a case of severe ulcerative esophagitis after failure of conventional medical and endoscopic treatment. A 77-year-old man with a history of peptic ulcer disease developed massive hematemesis during a hospital admission. Initial gastroscopy revealed an adherent blood clot occupying the distal esophagus, extending to the gastric cardia and proximal fundus. Epinephrine was injected into and surrounding the clot; however, following the endoscopy the patient was hemodynamically unstable, requiring aggressive resuscitation. Repeat gastroscopy, following saline lavage, revealed active bleeding within severely ulcerated esophageal mucosa, immediately proximal to the gastro-esophageal (GE) junction. Despite apparent hemostasis following injection of epinephrine and electrocautery, the patient displayed clinical signs of continued bleeding. Furthermore, surgical and radiological interventions were precluded by the patient's hemodynamic instability. In an attempt to tamponade blood supply to the GE junction, a Sengstaken-Blakemore tube was inserted and placed under tension. Successful hemostasis was subsequently achieved and the patient remained stable. This is the first case to describe use of a Sengstaken-Blakemore tube in severe ulcerative esophagitis refractory to standard endoscopic management.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
