We previously showed, in normal subjects, a positive correlation between the esophageal contraction amplitude and peak muscle thickness. The goal of this study was to determine the relationship between esophageal muscle thickness and contraction amplitude in patients with high-amplitude peristaltic and simultaneous contractions. Eleven patients with high-amplitude peristaltic contractions, 8 wi...
High-resolution manometry (HRM) is the primary method used to evaluate esophageal motor function. Displayed and interpreted by esophageal pressure topography (EPT), HRM/ EPT provides a detailed assessment of esophageal function that is useful in the evaluation of patients with nonobstructive dysphagia and before foregut surgery. Esophageal motility diagnoses are determined systematically by app...
Achalasia is characterized by loss of coordinated esophageal peristalsis and failure of the lower esophageal sphincter (LES) to completely relax. High resolution manometry distinguishes three subtypes [1, 2]. The Eckardt score evaluates clinical symptoms, but not quality of life [3]. The treatment aim is to decrease the LES pressure and the integrated relaxation pressure (IRP), in order to impr...
Megaesophagus is defined as the abnormal enlargement or dilatation of the esophagus, characterized by a lack of normal contraction of the esophageal walls. This is called achalasia when associated with reduced or no relaxation of the lower esophageal sphincter (LES). To date, there are few naturally occurring models for this disease. A colony of transgenic (Pvrl3-Cre) rats presented with megaes...
BACKGROUND All available treatments for achalasia are palliative and aimed to eliminate the flow resistance caused by a hypertensive lower esophageal sphincter. AIM To analyze the positive and negative prognostic factors in the improvement of dysphagia and to evaluate quality of life in patients undergoing surgery to treat esophageal achalasia by comparing findings before, immediately after, ...
