Physiology and Pathophysiology of the Lower Esophageal Sphincter
Annals of Otology, Rhinology & Laryngology, 1975The physiologic factors controlling lower esophageal sphincter (LES) function are interrelated in a complex fashion and include the autonomic nerve supply, gastrointestinal hormones, and specific characteristics of the circular smooth muscle at the esophagogastric junction. It might be expected that a defect in any of these three controlling mechanisms

Gastrin and Lower Esophageal Sphincter Tone
Archives of Internal Medicine, 1978The gastrointestinal polypeptide gastrin, found in great abundance in the gastric antrium, was shown in 1970 to have a very dramatic effect in stimulating the smooth muscle segment of the lower esophageal sphincter (LES), and in causing marked increases in pressure in this region.

Lower esophageal sphincter function in cirrhosis
The American Journal of Digestive Diseases, 1977Lower esophageal sphincter (LES) function in cirrhosis was evaluated using an infused manometric system. LES pressure (LESP) in 10 subjects with cirrhosis (22 +/- 1 mm Hg) (mean +/- SE) was not significantly (P greater than 0.05) different from that of 10 control subjects (21 +/- 1 mm Hg) but was significantly (P less than 0.01) greater than the LESP ...

Correlation of lower esophageal mucosal ring and lower esophageal sphincter pressure
Digestive Diseases and Sciences, 1994We assessed the relationship of lower esophageal sphincter pressure (LESP) to presence and absence of lower esophageal mucosal ring (LEMR) in 66 patients to determine if the LEMR was more likely related to prolonged sphincter hypotension. This potential relationship is of interest because LEMR may be due to reflux esophagitis.

The Lower Esophageal Sphincter Shown by a Computerized Representation
Scandinavian Journal of Gastroenterology, 1990The clinical application of manometry of the lower esophageal sphincter (LES) remains controversial. This is because of the large variability in recorded lower esophageal sphincter pressure (LESP). In this paper a computerized method providing a three-dimensional image of the LES is described.

Hypertensive Lower Esophageal Sphincter: A Reappraisal
Southern Medical Journal, 1978The hypertensive lower esophageal sphincter (LES) is defined as one with normal relaxation and an average LES-intragastric pressure gradient greater than or equal to 40 mm Hg. Case histories of two patients with hypertensive LES and normal peristalsis in the body of the esophagus are contrasted to that of a patient with a hypertensive LES and diffuse ...

The hypertensive lower esophageal sphincter
Digestive Diseases and Sciences, 1989Controversy exists as to whether the hypertensive lower esophageal sphincter (HLES) represents a clinical motility disorder of the esophagus or is merely the right-sided expression of a normal distribution curve. In the present study we describe 16 patients with HLES, defined as a lower esophageal sphincter (LES) pressure of greater than or equal to 40

Idiopathic Lower Esophageal Sphincter Incompetence and Esophageal Stricture
Archives of Internal Medicine, 1980Under normal circumstances, the lower esophageal sphincter (LES) acts as a pressure barrier at the gastroesophageal junction. When challenged by an increase in intra-abdominal pressure, the LES pressure correspondingly increases to maintain a dynamic equilibrium that prevents gastroesophageal reflux.
