Minimally invasive surgery, popularly known as "keyhole surgery", is a modern philosophy of patient care. With the integrated endosuites capable of robotic videoscopic surgery and monitor, a fine viewing instrument is inserted through a small incision or natural orifice (such as the mouth, anus and navel) to manoeuvre and treat or remove the diseased organ, instead of opening up a big incision on the body wall.
Minimally invasive surgery has set a new standard for the operative management of a wide variety of diseases across various surgical disciplines. The basic principles of operation, however, remain the same as in conventional surgery.
