Diagnosis of Acid reflux
DIAGNOSIS
Radiographic examination is performed with contrast, and take different positions, standing, lying etc … to observe large movements of fluids between the intestinal cavity. Allows you to diagnose large ebbs.
Another is the gastroscopy examination by a tube of cold light and vision in a monitor.Se used to observe the esophageal mucosal injury and the reflux itself.
To learn the characteristics of reflux studies were performed 24 hours pH monitoring, which should differentiate between normal and pathological reflux.
Normal or physiological reflux occurs in reflux episodes less than 5 minutes, being exceptional to find an episode lasting more than 10 minutes. When monitored by esophageal pH monitoring in a normal subject for 24 hours the time in which the pH remains below 4 in the esophagus is less than 3.4%. Ongoing pathological reflux reflux episodes with pH <4 for a long time, and occurrence at night or lying-lying.
