Schatzki Ring - Retroflexed View

Schatzki Ring retroflexed view. Lower Esophageal (Schatzki) Ring. Retroflexed endoscopic view of a Schatzki ring. Schatzki rings are almost invariably seen in association with hiatal hernia, as is the case here. The inner ring diameter of a Schatzki ring is an important determinant of whether the ring is associated with dysphagia. The ring diameter can be estimated when viewed from the retroflexed position by referencing the ring to the known diameter of the endoscope. The lower esophageal ring, also known as a Schatzki or mucosal Bring, is located at the squamocolumnar junction with a hiatal hernia. This is a thin mucosal membrane or diaphragm-like ring usually no more than 2-3 mm thick.
