An esophageal stricture is a narrowing of the food pipe (esophagus) that makes it harder for food and liquids to pass from your mouth to your stomach. This tight spot can cause discomfort, blockages, and difficulty swallowing (dysphagia).
He reviews your swallowing difficulties, reflux history, and other risk factors.
A flexible scope is used to directly visualize the esophagus and locate any strictures.
You drink a contrast solution so X-rays can highlight areas of narrowing or motility issues.
Small tissue samples are taken during endoscopy to rule out cancer or eosinophilic esophagitis.
