What are the tests for esophageal strictures?

These tests can help confirm an esophageal stricture:

• X-ray with barium: You swallow a solution containing barium. Then your provider takes X-rays of your neck and chest. As the barium travels down the esophagus, it highlights any problems so your provider can see them on the X-ray.
• Ultrasound: Detailed images can measure how thick the esophageal wall has become, which shows how much it is narrowing the esophagus.
• Endoscopy: A healthcare provider inserts an endoscope into your mouth and down your throat. The tool is a thin and flexible tube with a light and camera at the end. The healthcare provider can examine your esophagus. If needed, your provider can take a small piece of tissue to be tested for cancer (biopsy).
• Esophageal manometry: This test examines the esophageal muscles and sphincter. A small catheter tube is inserted into the nose and into the esophagus. This catheter measures the muscle and valve function of the esophagus during the swallow.
