Upper esophageal sphincter during transient lower esophageal sphincter relaxation: effects of reflux content and posture.
Although some studies show that the upper esophageal sphincter (UES) contracts during transient lower esophageal sphincter relaxation (TLESR), others show that it relaxes. We hypothesized that the posture of the subject and constituents of gastroesophageal reflux (GER) may determine the type of UES response during the TLESR. High-resolution manometry and esophageal pH/impedance recording were p...
متن کاملGastric mechanosensory and lower esophageal sphincter function in rumination syndrome.
Our hypothesis was that rumination syndrome is associated with gastric sensory and motor dysfunction. We studied gastric and somatic sensitivity, reflex relaxation of the lower esophageal sphincter (LES), and gastric compliance and accommodation postprandially and postglucagon. A barostatically controlled gastric bag and esophageal manometry were used to compare gastric sensorimotor functions a...
متن کاملAchalasia during Pregnancy Treated with Botulinum Toxin A Injection at the Lower Esophageal Sphincter
Achalasia is a rare motor disorder of the esophageal smooth muscle that occurs in 1 in 100,000 individuals. The disorder occurs at the level of the lower esophageal sphincter which does not relax normally with swallowing [1]. This leads to progressive dysphagia, chest pain and regurgitation of undigested foods and liquids. The underlying abnormality is loss of intramural neurons and is usually ...
متن کاملMechanics of sphincter action. Studies on the lower esophageal sphincter.
The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a function of the inside diameter. Various de...
