If it causes symptoms like pain or reflux it can be fixed either laparoscopically or robotically.

Hiatal hernia : A hiatal hernia is when the diaphragm that surrounds your esophagus as it passes from your chest to your abdomen is not tight but is loose. This allows acid reflux to occur. If the hernia is large, it can also allow your stomach to slide into your chest and cause more discomfort. You are either born with it, or you just develop it over time.
