Interpretation of a Manometric Trace of the Upper Esophageal Sphincter
TO THE EDITOR: While reporting the complexity behind the interpretation of the manometric trace of the upper esophageal sphincter (UES), Bhatia and Shah wrote: “It is a technically demanding procedure due to the anatomy of the UES, as is the movement of the sphincter during swallowing.” We agree with the authors that some of the difficulties are due to the movement of the sphincter during swall...
متن کاملManometric changes of the lower esophageal sphincter after sleeve gastrectomy in obese patients.
INTRODUCTION Laparoscopic sleeve gastrectomy has been accepted as an option for surgical treatment of obesity. After surgery, some patients present reflux symptoms associated with endoscopic esophagitis, therefore PPI's treatment must be indicated. PURPOSE This study aims to evaluate the manometric characteristic of the lower esophageal sphincter (LES) before and after sleeve gastrectomy MA...
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 کاملA dissection of a manometric trace of the upper esophageal sphincter and the crico-esophageal coordination.
A dissection of a manometric trace of the upper esophageal sphincter and the crico-esophageal coordination Although manometry is the most accurate method for diagnosing esophageal motility disorders, several patient suffering of high dysphagia remain undiagnosed. Most Authors concentrate their efforts in studying the coordination between the pharynx and the upper esophageal sphincter (UES), whi...
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...
