Assessment of esophageal motor function using combined multichannel intraluminal impedance and manometry in patients with achalasia

Conclusion Patients with achalasia are characterized by poor esophageal contraction and absent esophageal bolus clearance and such abnormalities are still noticeable after Heller myotomy. Although combined MII-EM can provide additional information regarding esophageal bolus transit, a low baseline impedance level and air trapping in the proximal esophagus may limit its utility in the diagnosis of esophageal dysmotility in patients with achalasia.
