Manometry Esophagus (Reflux)

Registration of an esophageal manometry in a normal newborn. At the top there are pressure values in mm mercury during the movement of the probe from the stomach to the esophagus (registration from the left to the right). At the bottom the distance from the probe opening to the nostril is given. In the region of the cardia and the gastroesophageal transition zone there is normally a high-pressure zone as depicted here with a pressure increase to the top, corresponding to a functioning gastroesophageal transition zone. This high-pressure zone is missing in gastroesophageal reflux. The manometry of the esophagus plays a minor role among the additional examinations in reflux.
