The HiRes esophageal manometry is a test that helps our Gastroenterologists determine if your esophagus is working properly. HiRes esophageal manometry will measure the force and coordination of esophageal muscles as they contract and move food to your stomach when you swallow. This procedure is typically done when patients have difficulty or pain swallowing and other tests have ruled out narrowing or blockage of the esophagus. This procedure can help diagnose more rare esophageal issues. During this procedure, a thin catheter will be inserted through your nose into your stomach to measure how well your muscles are working.
