Which of the following is a type of hiatal hernia?

A sliding hiatal hernia is the correct answer because it is one of the most common types of hiatal hernias. In a sliding hiatal hernia, the stomach and a portion of the esophagus slide up into the chest cavity through the diaphragm. This movement can lead to gastroesophageal reflux disease (GERD) as the lower esophageal sphincter may not function properly when displaced. Sliding hiatal hernias are often not accompanied by significant symptoms, making them more common and frequently diagnosed incidentally during other examinations.

Cervical, intestinal, and vertical are not types of hiatal hernias. Cervical typically pertains to the region of the neck; intestinal hernias refer to projections of the intestines through an opening in the abdominal wall; and vertical does not describe any known classification of hernias pertinent to this context. Understanding the type of hiatal hernia is important for determining the appropriate treatment and management strategies for patients experiencing related symptoms.
