Crohn's Disease of the Esophagus: Three Cases and a Literature Review
Bibliographic record
Abstract
Three cases of esophageal Crohn's disease (CD) are described, each with dysphagia and/or odynophagia caused by esophageal ulceration. All three patients had associated ileocolitis. One patient followed for a prolonged period responded to treatment with sulfasalazine and prednisone. A computer search back to 1967 produced 72 additional cases of esophageal CD. Among these 75 patients (total), who were, on average, 34 years old, esophageal disease was the presenting disease symptom in 41 patients (55%). The diagnosis was difficult in 13 patients, in whom no distal bowel disease was detected at the time of initial esophageal presentation. The most common presentation was dysphagia associated with aphthous or deeper ulcerations (52 patients). In 11 of these patients, oral aphthous ulcerations were also present. Esophageal stenosis or fistulas to surrounding structures were present in 27 patients and led to surgery in 17 patients. Most of the unfavourable outcomes were in this group of 27 patients with esophageal complications, including five deaths. Fourteen additional patients required surgery for CD of other areas. Responses of uncomplicated ulcerative disease of the esophagus tended to be favourable if the medical regimen included prednisone. Clinical patterns of esophageal CD were divided into three categories: ulcerative, stenosing and asymptomatic (acute disease in children).

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.
