Surgery
Definition
Surgery is the performance of a physical procedure (operation) within the tissues for the purposes of diagnosis and/or treatment.
Types of surgery
Surgery can be classified in many ways. The most common surgical operations involve cutting into the tissues and wound closure once the procedure has been completed. Incisions may be made using a scalpel, electrosurgery units, lasers or ultrasonic scalpels. Wounds are closed by "first intention" suturing, stapling, bandaging, use of adhesives or by "second intention" when the body is left to close the wound itself.
