Keyhole surgery (also called Laparoscopic surgery) is carried out through a small cut (or incision) in your skin rather than a large opening to your body. Many kinds of problems can be treated by keyhole surgery and because the wound is small, it means you get better quicker (so you can leave hospital earlier), leaves a smaller scar and causes less pain.
Keyhole surgery can be used to treat a number of bowel problems such as cancer, large polyps, diverticulitis, inflammatory diseases such as Crohn’s disease or ulcerative colitis.
Keyhole or minimally invasive surgery is a method of carrying out an operation without having to make a large incision. It is also known as laparoscopic surgery when used to operate on the abdomen and thoracoscopic surgery when used on the chest area.
Retro-sigmoid craniotomy (often called "keyhole" craniotomy) is a minimally-invasive surgical procedure performed to remove brain tumors. This procedure allows for the removal of skull base tumors through a small incision behind the ear, providing access to the cerebellum and brainstem.
