Oesophageal high-resolution manometry: moving from research into clinical practice

Area of Science:

• Gastroenterology
• Esophageal Physiology
• Diagnostic Technology

Background:

• Manometry assesses esophageal pressure and neuromuscular activity for diagnosing functional dysphagia, non-cardiac chest pain, and pre-surgical evaluation.
• Traditional manometry has evolved into high-resolution manometry (HRM) with advanced sensors and real-time spatiotemporal plotting.

Purpose of the Study:

• To review evidence supporting the clinical integration of high-resolution manometry (HRM).
• To evaluate if HRM improves diagnostic yield and accuracy for esophageal dysfunction compared to conventional methods.
• To discuss the potential of HRM for guiding esophageal disease treatment.

Main Methods:

• Review of current evidence on high-resolution manometry (HRM).
• Assessment of HRM's ability to identify clinically relevant esophageal dysfunction.
• Discussion of the need for a new classification system based on HRM data.

Main Results:

• HRM provides detailed, objective measurements of esophageal pressure activity.
• Spatiotemporal plots from HRM reveal complex esophageal and sphincter anatomy and function.
• HRM has been rapidly adopted into clinical practice.

Conclusions:

• HRM demonstrates potential to identify esophageal dysfunction missed by conventional investigations, increasing diagnostic accuracy.
• The development of a new classification system for esophageal motor activity based on HRM is needed.
• HRM's ultimate clinical success hinges on its ability to guide more effective treatments for esophageal diseases.
