Outcomes of esophageal surgery, especially of the lower esophageal sphincter.
This paper includes commentaries on outcomes of esophageal surgery, including the mechanisms by which fundoduplication improves lower esophageal sphincter (LES) pressure; the efficacy of the Linx™ management system in improving LES function; the utility of radiologic characterization of antireflux valves following surgery; the correlation between endoscopic findings and reported symptoms follow...
متن کاملHeller-Pinotti surgery to treat the hipertensive lower esophageal sphincter.
In the ethiological investigation of dysphagia, a mechanical obstruction in the esophageal tube of benign or a malign origin is almost always observed. However, a motor disorder must be considered in the absence of these findings. Hypertensive lower esophageal sphincter (HLES) is a type of motor disorder characterized by high pressure in the lower esophagus sphincter (LES) presenting a value hi...
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 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...
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...
