Manometric and radiologic correlations in achalasia

Area of Science:

• Gastroenterology
• Esophageal Motility Disorders
• Medical Diagnostics

Background:

• Achalasia is a complex esophageal motor disorder.
• Diagnosis relies on clinical, radiologic, and manometric features.
• Interrelationships between these features require further investigation.

Purpose of the Study:

• To evaluate the correlation among clinical, radiologic, and manometric findings in achalasia patients.
• To identify factors influencing the consistency of these correlations.

Main Methods:

• Analysis of clinical complaints, radiologic findings, and manometric parameters in 109 achalasia patients.
• Utilized correlation matrix and multiple regression analyses.
• Examined relationships between specific symptoms and diagnostic findings.

Main Results:

• Significant correlations found between dysphagia, regurgitation, and weight loss.
• Chest pain showed an inverse correlation with these symptoms.
• Dysphagia and weight loss correlated with bird-beak deformity, but not esophageal dilatation or sigmoid esophagus.
• Correlation between lower esophageal sphincter pressure and esophageal dilatation/sigmoid esophagus was not significant.
• A reasonable correlation existed in patients with resting lower esophageal sphincter pressure > 45 mm Hg.

Conclusions:

• Correlation between clinical, radiologic, and manometric findings in achalasia is variable.
• Esophageal dilatation or sigmoid esophagus may not solely indicate disease severity or hypertensive sphincter.
• Chest pain has an inverse relationship with other key achalasia symptoms.
• Achalasia and hiatal hernia can coexist.
