Practical aspects of high resolution esophageal manometry

Area of Science:

• Gastroenterology
• Digestive Motility

Background:

• High resolution esophageal manometry (HRM) is a developing diagnostic tool.
• Current Chicago classifications highlight ongoing advancements in HRM.
• Limited scientific evidence necessitates standardization of practical HRM criteria.

Purpose of the Study:

• To standardize practical criteria for high resolution esophageal manometry (HRM).
• To address areas with limited scientific evidence in HRM analysis.
• To consolidate expert experience and literature review for practical guidelines.

Main Methods:

• Convened the First National Meeting for Consensus in High Resolution Manometry.
• Conducted a survey with 47 questions among experts.
• Performed an exhaustive literature review.
• Incorporated participant experience in discussions.

Main Results:

• Discussed methodological aspects of HRM analysis criteria.
• Addressed poorly defined new high resolution parameters.
• Considered overlooked issues like spontaneous activity and secondary waves.

Conclusions:

• Established practical consensus criteria for HRM.
• Provided guidelines for standardized HRM data interpretation.
• Facilitated practical applications in clinical settings.
