Hypercontractile Esophagus Causing Midesophageal Diverticulum.

Esophageal diverticulum (ED) is a rare condition with a clinical presentation that can be variable. Esophageal diverticulum has been associated with motility disorders; however, the association with mid-ED is less clear. Hypercontractile esophagus, also known as jackhammer esophagus, is a rare motility disorder of peristalsis diagnosed by esophageal high-resolution manometry after exclusion of mechanical obstruction. We describe the second reported case of mid-ED secondary to hypercontractile esophagus successfully treated through robotic diverticulectomy with long myotomy. KEYWORDS: esophagus; esophageal manometry; motility; diverticular disease.
