ANSWERS AND EXPLANATIONS






1  Answer A.Spot image from a double-contrast esophagram demonstrates upward herniation of the stomach into the chest with superior migration of the gastroesophageal junction. This is compatible with a type I hiatal hernia, also called a sliding hiatal hernia. Type I hiatal hernias account for 85% to 95% of all hiatal hernias and are associated with diffuse weakening of the phrenoesophageal membrane, which normally fixes the distal esophagus near the hiatus. This laxity allows the upward displacement of the gastroesophageal junction and stomach into the chest through the diaphragmatic hiatus. Patients with type I hiatal hernias can also have diminished lower esophageal sphincter tone and therefore often present with symptoms of gastroesophageal reflux.


The other types of hernias listed (types II to IV) are paraesophageal hernias and will be discussed in a later question.

2  Answer B.Spot image from double-contrast upper GI study demonstrates a normally positioned gastroesophageal (GE) junction (image on left) with adjacent herniation of the gastric fundus above the diaphragm (image on the right). This is compatible with a type II paraesophageal hiatal hernia. Paraesophageal hernias result from a focal defect in the phrenoesophageal membrane that provides a small opening for upward gastric herniation, generally beginning with the gastric fundus.


In the surgical literature, hiatal hernias are generally classified into two major groups: sliding and paraesophageal hernias.



Types of Hiatal Hernias

The above example of the type III hernia demonstrates elevation of the GE junction above the level of the diaphragmatic hiatus as well as herniation of a segment of the fundus adjacent to the GE junction and distal esophagus. The type IV hernia images show a large hernia containing fat and a portion of the colon.
