Medically we define a hernia as a protrusion of an organ or the tissues that surround it through the wall of the cavity that normally contains it and surgery is the main way to treat them.  There are two main types of surgery:  Open surgery and Laparoscopic surgery, also known as minimally invasive surgery (MIS), or keyhole surgery, which is a quicker, less invasive option enabling much faster recovery with equally effective outcomes.
