Stomach hernia. Gastroscope (endoscope) view of a hiatal hernia, a type of hernia that occurs when a portion of the stomach protrudes through the diaphragm. Also seen is Schatzki's ring (pink), also known as a "B ring", which causes a narrowing of the lower part of the oesophagus. Schatzki's ring occurs as a congenital defect and may cause food to build up around it, which may require removal to stop infection occurring. The folding of the cavity (lumen, centre) indicates where the diaphragm compresses the stomach.
