Primary achalasia: analysis of endoscopic ultrasonography features with different instruments.
The examination of patients with primary achlasia using classical radial endoscopic ultrasonography lacks accuracy and has yielded inconclusive results. The diameter of the scope and the presence of a balloon makes examination of a short stenotic segment difficult. These techniques, however, are useful in the evaluation of patients with suspected pseudoachalasia due to tumor infiltration.
