Laparoscopic antrectomy: a novel approach to treating watermelon stomach
Bibliographic record
Abstract
Watermelon stomach, a subset of gastric antral vascular ectasia (GAVE), is a rare but significant cause of gastrointestinal blood loss. The disease usually presents in the elderly, primarily in women. GAVE was first recognized in 1984; Jabbari and colleagues described the endoscopic appearance as parallel longitudinal red columns along mucosal folds, radiating from the pylorus and resembling the exterior of a watermelon. Diagnosis cannot be made solely on endoscopic appearance because the mucosal appearance may be confused with gastritis. GAVE may also present as a punctate type in which sharply demarcated, punctate red spots are diffusely scattered throughout the antrum. Diagnosis is confirmed pathologically; the dominant features have been described as dilated mucosal capillaries, often with fibrin thrombi, and fibromuscular hyperplasia of the lamina propria. A wide variety of treatments have been reported in the literature including long-term corticosteroids, eel calcitonin injection, -interferon, coagulation with argon plasma coagulator, neodymium:yttrium-aluminum garnet laser therapy, and antrectomy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
