Mechanics 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...
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 کاملSafe Esophageal Bougie Placement for Laparoscopic Hiatal Hernia Repair
The increased use of laparoscopy for treatment of reflux esophagitis has been associated with a 1-8% complication rate. Perforation of the esophagus from bougie placement, wrap breakdown or too tight a wrap are some of the complications seen from this surgery. An esophageal dilator system was developed to overcome these problems. Thirty patients had an esophageal dilator system used whereby a 4...
متن کاملPharmacologic identification of the lower esophageal sphincter.
The distal 2/3 of the opossum esophagus contains only smooth muscle. Manometry shows that the most distal 1-2 cm is the lower esophageal sphincter. We used a variety of agonists to seek differences between circular muscle from the sphincteric segment and more rostral levels. Isometric contractions of strips from the distal 6 cm were recorded in vitro in response to acetylcholine, carbachol, met...
متن کاملPathophysiology of GERD: Lower Esophageal Sphincter Defects
44 INTRODUCTION T he most common cause of gastroesophageal reflux disease (GERD) is lower esophageal sphincter (LES) dysfunction. The LES is a 3–4 cm high-pressure zone of muscular activity in the distal esophagus. The LES is anatomically and histologically distinct from the esophageal body. Manometric and radiographic studies can be used to identify the LES. Intraluminal manometry can detect t...
