Abstract
A 76-year-old previously healthy male presenting with ascending paralysis was diagnosed with Guillain-Barre syndrome. Due to respiratory failure, he underwent tracheostomy and had nasojejunal and nasogastric feeding tube placed fluoroscopically without immediately apparent complication. Esophagogastroduodenoscopy performed for abdominal pain demonstrated a mucosal bridge at 25 cm from the incisors (Figure 1). Endoscopic finding of esophageal mucosal bridge. An oesophageal mucosal bridge is a smooth muscle that extends and connects across the lumen of the esophagus, rarely found through upper endoscopy.1 It is described to be visualized as a “double lumen” on upper endoscopy due to the connecting smooth muscle, and can cause various symptoms including dysphagia and bleeding.1 However, mucosal bridges are often asymptomatic in nature, which probably contributes to underdiagnosis. The aetiology of this condition may either be congenital or acquired secondary to oesophageal trauma and inflammation.2 One of the known causes of oesophageal mucosal bridge is nasoenteric tube insertion and use associated with oesophageal mucosal injury.3 As this condition is exceedingly rare, more studies and case reports are needed to understand the full scope of pathogenesis, aetiology, and effective treatment.

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.
