Endoscopic Mucosal Resection of Esophageal Squamous Papillomatosis
Bibliographic record
Abstract
A 62-year-old woman was referred for investigation of heartburn.She did not have any other significant medical history and denied any other symptoms including weight loss, dysphagia, odynophagia, regurgitation and hematemesis.Her only medication was pantoprazole 40 mg daily for her gastroesophageal reflux disease.Endoscopy was performed with a GIF-Q180 gastroscope (Olympus Optical, Japan), which demonstrated multiple flesh-coloured pedunculated papules at the gastroesophageal junction (Figure 1).Biopsies demonstrating atypical epithelial proliferation confirmed the diagnosis of esophageal squamous papillomatosis, without the presence of dysplasia or carcinoma.A polymerase chain reaction study was negative for herpes simplex virus.Following discussion with the patient, an extensive endoscopic mucosal resection (EMR) incorporating all of the lesions was performed using a band mucosectomy device (Duette, Cook Medical, Ireland) (Figures 2 and 3).Histology from the EMR specimens was similar to the original mucosal biopsy results.No immediate or delayed complications occurred.

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.
