Endoscopic submucosal dissection in a patient with esophageal adenoid cystic carcinoma.

We report the first use of endoscopic submucosal dissection (ESD) for the treatment of a patient with adenoid cystic carcinoma of the esophagus (EACC). An 82-year-old woman visited our hospital for evaluation of an esophageal submucosal tumor. Endoscopic examination showed a submucosal tumor in the middle third of the esophagus.

Gastroesophageal flap valve status distinguishes clinical phenotypes of large hiatal hernia.

Aim: To investigate two distinct clinical phenotypes of reflux esophagitis and intra-hernial ulcer (Cameron lesions) in patients with large hiatal hernias.

Methods: A case series study was performed with 16 831 patients who underwent diagnostic esophagogastroduodenoscopy for 2 years at an academic referral center. A hiatus diameter ≥ 4 cm was defined as a large hernia.
