Effect of spasmolytic drugs on esophageal foreign bodies.

Muscle spasm has been proposed as the cause for esophageal food impaction. The aim was therefore to treat esophageal foreign bodies with spasmolytic drugs influencing both striated and smooth muscles of the esophagus. A multicenter, placebo-controlled, double-blind study of glucagon and diazepam was undertaken in 43 patients.
