Hernias can occur in many places, including the abdomen, groin, diaphragm, brain, and at the site of a previous operation. There are many different approaches to the surgical repair of hernias, including herniorrhaphy, hernioplasty, and herniotomy. Hernia repair is often performed as an ambulatory procedure.
