Can high resolution manometry parameters for achalasia be obtained by conventional manometry?

Treatment of achalasia in the era of high-resolution manometry

Esophageal achalasia is a primary motility disorder characterized by impaired lower esophageal sphincter relaxation and absence of esophageal peristalsis leading to impaired bolus transit, manifested with symptoms such as dysphagia, regurgitation, retrosternal pain, and weight loss. The standard diagnostic tool is esophageal manometry which demonstrates incomplete relaxation of the lower esopha...

Can Achalasia Subtyping by High-Resolution Manometry Predict the Therapeutic Outcome of Pneumatic Balloon Dilatation?

TO THE EDITOR: I read with great interest the paper entitled “Achalasia cardia subtyping by high-resolution manometry predicts the therapeutic outcome of pneumatic balloon dilatation” by Pratap et al, which was published in January 2011 issue of Journal of Neurogastroenterology and Motility. Achalasia is the best known primary esophageal motility disorder characterized by absent peristalsis of ...

Impact of high-resolution manometry on achalasia diagnosis and treatment

Achalasia is a primary neurodegenerative disorder of the esophagus characterized by loss of function of the lower esophageal sphincter (LES) and of esophageal peristalsis, which causes symptoms such as dysphagia, regurgitation, weight loss, and chest pain. Esophageal manometry is the gold standard for the diagnosis of achalasia. The typical manometric features are incomplete relaxation of a fre...

High resolution manometry – an introduction

A Pictorial Presentation of Esophageal High Resolution Manometry Current Parameters

Introduction: High resolution manometry is the current technology used to the study of esophageal motility and is replacing conventional manometry in important centers for esophageal motility with parameters used on esophageal motility, following the Chicago Classification. This classification unifies high resolution manometry interpretation and classifies esophageal disorders. Objective: Thi...
