Botulinum toxin in the treatment of diffuse esophageal spasm
Bibliographic record
Abstract
Diffuse esophageal spasm is a primary esophageal motility disorder. The prevalence is 3-10% in patients with dysphagia and treatment options are limited. This review summarizes the treatment of diffuse esophageal spasm, including pharmacotherapy, endoscopic treatment, and surgical treatment with a special focus on botulinum toxin injection. A PubMed search was performed to identify the literature using the search items diffuse esophageal spasm and treatment. Pharmacotherapy with smooth muscle relaxants, proton pump inhibitors, and antidepressants was suggested from small case series and uncontrolled clinical trials. Endoscopic injection of botulinum toxin is a well-studied treatment option and results in good symptomatic benefit in patients with diffuse esophageal spasm. Surgical treatment was reported in patients with very severe symptoms refractory to pharmacologic treatment. This article summarizes the present knowledge on the treatment of diffuse esophageal spasm with a special emphasis on botulinum toxin injection. Endoscopic injection of botulinum toxin is presently the best studied treatment option but many questions remain unanswered.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
