Esophageal manometry may be combined with multichannel intraluminal impedance to obtain pressure and bolus transit information. [19, 20] About half of the patients with diffuse esophageal spasm have normal transit for liquids and fluids, one fourth have abnormal transit for one substance, and one fourth have abnormal transit for both.

Esophageal pH recording and 24-hour ambulatory manometry may improve the detection of esophageal muscle dysfunction. [21] This method shows that in persons presenting with noncardiac chest pain, gastroesophageal reflux symptoms are common and diffuse esophageal spasm is rare.
