Endoscopic Pneumatic Dilation in Achalasia Cardia

Abstract: Achalasia cardia is a primary esophageal motility disorder characterized by aperistalsis and incomplete or absent relaxation of the lower esophageal sphincter. Pneumatic dilatation is the first-line nonsurgical therapy for achalasia. The principle of this procedure is to weaken the lower esophageal sphincter by controlled tearing of esophageal muscle fibers generated by the radial force of the balloon. Demonstrated here is the technique of pneumatic balloon dilatation of the lower esophageal sph
