Features Halitosis Regurgitation of previous day food If diveiculum fills completely with food,can cause dysphagia or obstruction of esophagus. Mallory-Weiss tear (option A) - Mucosal tear below gastroesophageal junction secondary to repeated, forceful vomiting; often seen in alcoholics. Schatzki rings (option C) are mucosal rings found in distal esophagus at squamocolumnar junction.

They are typically caused by adherence of esophagus to scarred mediastinal structure.
