To the Editor.—In their article, "Glucagon and Esophageal Meat Impaction" (Arch Otolaryngol 105:367-368, 1979), Drs Marks and Lousteau described the advantages of glucagon therapy on esophageal relaxation and the passage of foreign bodies caught in the esophagus. Intravenous glucagon can be an effective means of relaxing the esophageal smooth muscle. But, following this treatment, there is still no direct visual evidence of what caused the impaction in the first place. Treatment without diagnosis on a large number of patients could result in an increased number of missed esophageal lesions.
I hope this form of therapy is not viewed as a panacea for all esophageal obstructive problems to the exclusion of proper diagnostic steps in these patients.
