<unk> s (also known as<unk><unk>  surgeries) encompass surgical techniques that limit the size of incisions needed and so lessen wound healing time, associated pain and risk of infection. Surgery by definition is<unk>  and many operations requiring incisions of some size are referred to as open surgery, in which incisions made can sometimes leave large wounds that are painful and take a long time to heal.<unk> s have been enabled by the advance of various medical technologies. An endovascular aneurysm repair as an example of<unk><unk>  surgery is much less<unk>  in that it involves much smaller incisions than the corresponding open surgery procedure of open aortic surgery. This<unk><unk>  surgery became the most common method of repairing abdominal aortic aneurysms in 2003 in the United States. The front-runners of<unk> s were interventional radiologists. By the use of imaging techniques, interventional instruments could be directed throughout the body by the radiologists by way of catheters instead of large incisions needed in traditional surgery, so that many conditions once requiring surgery can now be treated non-surgically. Diagnostic techniques that do not involve the puncturing of the skin or incision, or the introduction into the body of foreign objects or materials, are known as non-invasive procedures. There are also several treatment procedures that are classed as non-invasive. A major example of a non-invasive alternative treatment to surgery is radiation therapy, also called radiotherapy.
