High-resolution Manometry: Esophageal Disorders Not Addressed by the "Chicago Classification"

Area of Science:

• Gastroenterology
• Esophageal Physiology
• Diagnostic Imaging

Background:

• High-resolution esophageal manometry (HRM) and the Chicago classification have advanced esophageal motility disorder diagnosis.
• Current classifications do not encompass all observed HRM findings.
• There is a need to expand diagnostic capabilities for complex esophageal conditions.

Purpose of the Study:

• To review and describe high-resolution esophageal manometry (HRM) findings not currently included in the Chicago classification.
• To discuss the utility of HRM in evaluating specific conditions like rumination syndrome and post-surgical patients.
• To propose the incorporation of new manometric criteria into the existing classification.

Main Methods:

• Review of high-resolution esophageal manometry (HRM) data and clinical experience from a single center.
• Analysis of findings related to the upper esophageal sphincter, proximal esophagus, and longitudinal muscle contraction.
• Discussion of provocative tests and HRM applications in specific patient groups.

Main Results:

• Identification of several HRM findings not covered by the current Chicago classification.
• Exploration of HRM's role in diagnosing disorders associated with GERD and respiratory symptoms.
• Evaluation of HRM's utility in rumination syndrome and post-surgical assessments.

Conclusions:

• Characterizing unclassified HRM findings is crucial for comprehensive esophageal motility disorder diagnosis.
• Expanding the Chicago classification based on novel HRM data will improve patient management.
• Further research and data collection are needed to refine and incorporate new criteria.
