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.

Efficacy of Endoscopic Mucosal Resection for Management of Small Duodenal Neuroendocrine Tumors.

Background: Endoscopic mucosal resection (EMR) for small (<20 mm) duodenal neuroendocrine tumors (NETs) remains controversial because of their rarity.

Materials And Methods: This is a retrospective cohort study of patients with surgically or endoscopically resected duodenal NETs from 2001 to 2011. The primary outcome is the rate of disease-free status following resection.
