Telesurgery is an aspect of telemedicine in which the doctor can perform a surgery without being present in the same physical location as the patient. Telesurgery makes available the expertise of surgeons to patients without the patients being required to travel to the surgeon. Telesurgery, also known as remote surgery, makes use of robots which are usually manipulated by other surgeons present at the operating theater. Telesurgery may lead to unassisted robotic surgery. For now, the issues facing telesurgery include the establishment of global standards to be followed in terms of procedure and equipment. One limitation of telesurgery is the potential for a breakdown in communication and robot malfunction. This necessitates the presence of an anesthetist and a backup surgeon.
