Oral nitroglycerin solution for oesophageal food impaction: a prospective single-arm pilot study.

Background: Thirteen episodes of oesophageal food impaction (EFI) per 100 000 people present to a medical setting each year. Several pharmacological interventions meant to relieve such impactions have been explored; none have proven superior.

Objectives: Perform a single-arm feasibility study of oral nitroglycerin solution for EFI.

Oral Nitroglycerin Solution May Be Effective for Esophageal Food Impaction.

Background: Esophageal food impaction is a common illness presenting to emergency departments (ED), and is frequently resistant to pharmacologic therapy. Several medications have been promoted for this indication, but so far have not proven effective. Endoscopic removal is frequently required to resolve the impaction, resulting in risks from anesthesia and the physical procedure, and in prolonged hospital stay for recovery.
