Midesophageal Pulsion Diverticulum Resulting From Hypercontractile (Jackhammer) Esophagus.

We report a patient with significant dysphagia from hypercontractile "jackhammer" esophagus and a midesophageal pulsion diverticulum. This was treated with a thoracoscopic diverticulectomy and a long esophageal myotomy sparing the lower esophageal sphincter (LES). We describe the clinical diagnosis and surgical treatment of this uncommon esophageal motility disorder. To our knowledge, this is the first report in the literature of a midesophageal diverticulum caused by jackhammer esophagus. We propose that in the setting of normal LES function, successful treatment should include diverticulectomy with an LES-sparing myotomy.
