Symptom and function heterogenicity among patients with distal esophageal spasm: Studies using combined impedance-manometry
Esophageal Spasm, Diffuse
Signal Processing, Computer-Assisted
Pressure and bolus transit information in patients with manometrically defined DES points toward heterogenicity of this group of patients. Outcomes data are warranted to evaluate whether stratifying DES patients based on pressure and bolus transit information may improve the clinical approach.
