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.

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.

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 ...

Transient Lower Esophageal Sphincter Relaxation and Esophageal Motor Response
Journal of Surgical Research, 2010Gastroesophageal reflux is caused by transient lower esophageal sphincter relaxations (TLESRs) in healthy individuals and in most patients with gastroesophageal reflux disease (GERD). Refluxate is normally propelled by pharyngeally induced swallowing events, but TLESRs may also be accompanied by retrograde esophageal motor responses (EMRs).

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 ...

Magnetic lower esophageal sphincter augmentation device removal
Surgical Endoscopy, 2014Implantation of a magnetic lower esophageal sphincter augmentation device is now an alternative to fundoplication in the surgical management of gastroesophageal reflux disease (GERD). Although successful management of GERD has been reported following placement of the device, there are instances when device removal is needed.

Lower esophageal sphincter pressure in Chagas' disease
Digestive Diseases and Sciences, 1990It is known that lower esophageal sphincter (LES) pressure in patients with idiopathic achalasia is higher than in normal subjects, but in patients with Chagas' disease, who have esophageal disease with similar clinical, manometric, and radiologic results, studies of LES pressure show contradictory findings. We measured the LES pressure in 118 patients

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.

Central mechanisms of lower esophageal sphincter control
Gastroenterology Clinics of North America, 2002Lower esophageal sphincter (LES) tone is decreased during swallowing, during transient LES relaxations (TLESRs), and before emesis, and this decrease is due primarily to increasing inhibitory vagal output to the LES. Reflex-evoked relaxation of the LES is mediated by long-loop vagovagal reflexes that are coordinated by the dorsal vagal complex in the ...

Transient lower esophageal sphincter relaxation.
Nihon rinsho. Japanese journal of clinical medicine, 2019Transient lower esophageal sphincter relaxation(TLESR) is the single most common mechanism underlying acid reflux in normal subjects and patients with gastroesophageal reflux disease (GERD). It is also the mechanism underlying the reflux of gas during belching. By definition, TLESRs are not triggered by swallowing.
