Abstract:
We describe a patient with dysphagia. The results of endoscopy, CT scan and echoendoscopy were normal. High-resolution manometry (HRM) showed esogastric junction dysfunction and hypercontractile peristaltic disorder. These HRM abnormalities completely disappeared after pneumatic esophageal dilatation. We discuss the treatment options and recovery of peristalsis after balloon dilatation.
