==Description==
'''Surgery''' (from the [[Greek]]: χειρουργική ''cheirourgikē'', via [[Latin]]: ''chirurgiae'', meaning "hand work") is an [[ancient]] medical specialty that uses operative manual and instrumental [[techniques]] on a patient to investigate and/or treat a pathological condition such as [[disease]] or [[injury]], or to help improve bodily [[function]] or [[appearance]].

An [[act]] of performing surgery may be called a surgical [[procedure]], operation, or simply surgery. In this [[context]], the verb operate means to perform surgery. The adjective surgical means pertaining to surgery; e.g. surgical instruments or surgical nurse. The patient or subject on which the surgery is performed can be a [[person]] or an [[animal]]. A surgeon is a person who [[practices]] surgery. Persons described as surgeons are commonly [[physicians]], but the term is also applied to podiatrists, dentists (known as oral and maxillofacial surgeons) and [http://en.wikipedia.org/wiki/Veterinarian veterinarians]. A surgery can last from minutes to hours, but is typically not an ongoing or periodic type of treatment. The term surgery can also refer to the place where surgery is performed, or simply the office of a physician, dentist, or veterinarian.

Elective surgery generally refers to a surgical procedure that can be scheduled in advance because it does not involve a medical [[emergency]]. Cosmetic surgeries are common elective procedures.[http://en.wikipedia.org/wiki/Surgery]
