Telesurgery

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.

Hair Loss after Bariatric Surgery

Although not essential to health, scalp hair can be important to self-image and hair loss or alopecia may lead to significant psychological distress. Some degree of hair loss is relatively common following bariatric surgery, usually occurring 3 months or more after surgery and affecting around athird of all patients. The precise causes of post-bariatric hair loss are unknown; factors including changes in nutritional status and the impact of surgery upon the hair growth cycle are thought to be involved. In most cases, hair will begin to regrow without intervention once weight has stabilized.
