Abstract
Sixteen patients with achalasia of the esophagus were treated by fluoroscopically guided pneumatic dilatation. All patients were examined radiographically immediately following dilatation. The caliber of the esophagogastric region increased from a pretreatment mean of 5.3 mm to 9.6 mm following dilatation. The margins of the dilated area remained smooth in 6 patients (38%) and became irregular in 10 (62%). Initial symptomatic improvement was found in 14 patients (88%) with a mean follow-up of 1.7 months. One (6%) perforation occurred, necessitating surgery. The radiographic appearance of the esophagogastric region following pneumatic dilatation, however, poorly predicted patient response.
