Ineffective Esophageal Motility is Associated with Impaired Bolus Clearance but does not Correlate with Severity of Dysphagia
BACKGROUND: Ineffective esophageal motility (IEM) is defined as a distal contractile integral 0.01). There was a moderate inverse correlation between dysphagia and percent bolus clearance (R = - 0.37) in group A, but none in group B (R = 0.09). CONCLUSION: The classification of IEM did not discriminate from normal studies for symptom severity in our cohort. However, patients with IEM did have an inverse correlation between dysphagia score and bolus clearance, but those without IEM did not. Adding impedance information to the motor pattern classification should be considered in the symptom assessment in minor motility disorders.
