3. Sliding Hiatal Hernia
Hiatal hernias can be categorized into two main subtypes: sliding hernias and paraesophageal hernias. Roughly 95 percent of hiatal hernias are sliding hernias. According to current anatomical classifications, a type I hernia is a sliding hiatal hernia, which will migrate or slide through the diaphragmatic hiatus into the thoracic cavity.
In this case, the gastroesophageal junction, or the point where the distal esophagus joins the proximal stomach, is the part of the abdominal digestive tract that ascends above the diaphragm. Importantly, the stomach remains in its longitudinal alignment and the upper domed- shaped part of the stomach (fundus) remains below said junction.
