More popularly called ‘keyhole surgery’, MIS is surgical intervention, whether diagnostic or curative, that causes patients the least possible physical trauma. It has revolutionised surgery, growing from a technique used by gynaecologists, urologists and innovative general surgeons to one regularly used in general surgery, GYNAECOLOGY, UROLOGY, thoracic surgery, orthopaedic surgery (see ORTHOPAEDICS) and OTORHINOLARYNGOLOGY.

MIS is commonly carried out by means of an operating laparoscope (a type of ENDOSCOPE) that is slipped through a small incision in the skin. MIS now accounts for around 50 per cent

of all operations carried out in the UK. A small attachment on the end of the laparoscope provides an image that can be magni?ed on a screen, leaving the surgeon’s hands free to operate while his assistant operates the laparoscope. Halogen bulbs, ?breoptic cables and rod lenses have all contributed to the technical advancement of laparoscopes. Operations done in this manner include extracorporeal shock-wave LITHOTRIPSY for stones in the gall-bladder, biliary ducts and urinary system; removal of the gall-bladder; appendicectomy; removal of the spleen and adrenal glands; and thoracic sympathectomy. MIS is also used to remove cartilage or loose pieces of bone in the knee-joint.

This method of surgery usually means that patients can be treated on a day or overnight basis, allowing them to resume normal activities more quickly than with conventional surgery. It is safer and lessens the trauma and shock for patients needing surgery. MIS is also more cost e?ective, allowing hospitals to treat more patients in a year. Surgeons undertake special training in the use of MIS, a highly skilled technique, before they are permitted to use the procedures on patients. The use of MIS for hernia repair, colon surgery and repairs of duodenal perforations is under evaluation and its advantages will be enhanced by the development of robotic surgical techniques.... minimally invasive surgery (mis)
