Esophageal manometry revealed that the patient had an incompetent lower esophageal sphincter (LES), based on a resting pressure of only 3 mm Hg (figure 2); normal LES resting pressure ranges between 15 and 35 iron Hg (figure 3).
Potential Etiologies for Running-Related Gastroesophageal Reflux Lower Esophageal Sphincter Relaxation The lower esophageal sphincter (LES) is a relatively high pressure zone which separates the stomach from the esophagus.
Dynogen's preclinical studies have shown that DDP733 enhances the motility of the esophagus and tightens the lower esophageal sphincter between the esophagus and the stomach, thereby impeding the reflux of stomach contents into the esophagus and reducing the exposure of the lower esophagus to potentially harmful gastric contents.
Gastroesophageal reflux (GER) also might have contributed to her insult; GER is well known to be exacerbated by nasogastric intubation, because it impairs the closure of the lower esophageal sphincter.
