Hiatal Hernia Seen From Below
This is a view of the fundus, or top part of the stomach seen during a gastroscopy examination. As part of the normal examination, the doctor uses the steering controls to turn the scope back upon itself. This so-called retroflexion allows a view of the upper part of the stomach organ from below.
Normally the valve between the esophagus and stomach is tight and wraps firmly around the instrument. In this video, you can see there is a lot of extra room between the scope and this valve. This is caused by a hiatal hernia where a portion of the stomach slides upward into the chest. A hiatal hernia is often associated with acid reflux up into the esophagus in a condition called GERD.
