High-resolution manometry offers insights into the esophagogastric junction anatomy and physiology. This technique aids in diagnosing achalasia subtypes and evaluating post-fundoplication dysphagia.

Area of Science:

  • Gastroenterology
  • Esophageal Physiology
  • Diagnostic Imaging

Background:

  • The esophagogastric junction (EGJ) plays a critical role in esophageal function.
  • Understanding EGJ anatomy and physiology is essential for diagnosing motility disorders.
  • High-resolution manometry (HRM) has emerged as a key tool in esophageal diagnostics.

Purpose of the Study:

  • To elucidate the utility of high-resolution manometry (HRM) in understanding EGJ anatomy and physiology.
  • To review the application of HRM in classifying achalasia subtypes.
  • To discuss the role of HRM in evaluating dysphagia after fundoplication surgery.
  • To outline the appropriate clinical protocol for performing HRM.

Main Methods:

  • Commentaries synthesizing existing literature and clinical experience.

  • Review of HRM data interpretation for EGJ disorders.
  • Analysis of HRM findings in patients with achalasia and post-surgical dysphagia.

    • Main Results:

    • HRM provides detailed insights into EGJ pressure topography and dynamics.
    • HRM facilitates objective classification of achalasia into distinct subtypes.
    • HRM is valuable for identifying the etiology of dysphagia in patients who have undergone fundoplication.

    Conclusions:

    • High-resolution manometry is indispensable for a comprehensive understanding of esophagogastric junction function.
    • HRM enables precise diagnosis and subtyping of achalasia.
    • HRM is crucial for the etiological evaluation of dysphagia in the post-fundoplication setting.
    • Standardized HRM protocols ensure reliable and reproducible diagnostic outcomes.
