Lower esophageal sphincter pressure measurement under standardized inspiratory maneuveurs.
BACKGROUND Through rhythmic variations, the diaphragm influence lower esophageal sphincter (LES) pressure acting as an external sphincter. LES pressure recording is characterized by increased pressure in inspiration due to contraction of the diaphragmatic crura that involves the sphincter. AIM To describe a method of measuring LES pressure during standardized inspiratory maneuvers with increa...
متن کاملMeasurement of Lower Oesophageal Sphincter Pressure
In 24 control patients the lower oesophageal sphincter responded to graded increments in intra-abdominal pressure by a significant and sustained rise in tone. This response was abolished by atropine and was also absent in nine of 11 patients who had previously undergone truncal vagotomy for duodenal ulcer but not in the remaining two who had recurrent ulceration. In six patients studied after p...
متن کاملEffect of ginger on lower esophageal sphincter pressure.
OBJECTIVE Ginger has been traditionally used to reduce intestinal gas and flatulence. The present study examined the effects of ginger on the esophagus and lower esophageal sphincter (LES) function by esophageal manometry. STUDY DESIGN A randomized controlled trial.

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...
