Esophageal manometry is an effective diagnostic technique for patients suffering from heartburn, swallowing difficulties, or chest discomfort. During this procedure, the patient’s throat and nasal cavity are anesthetized, and a thin, flexible tube is inserted via the nose into the upper GI tract. A GastroHub gastroenterologist will insert the tube from the back of the throat, through the esophagus, and into the stomach via the esophageal sphincter valve to diagnose the esophageal condition. At GastroHub, esophageal manometry will not only analyze swallowing movements but also how effectively the esophageal sphincter functions to avoid reflux. People who often vomit or suffer from acid reflux (GERD) are suitable candidates for esophageal manometry.
