This video demonstrates a hiatal hernia as a pouch like area just distal to the squamocolumnar junction above the diaphragm. The gastroscope is then passed into the stomach where the hiatal hernia is better visualized with a retroflexed view. A widely patulous hiatal opening and the abnormal gastroesophageal flap valve is seen. The gastroesophageal area is open with a significant amount of space around the instrument. Moreover, the squamocolumnar junction can be seen through all phases of respiration.
