Laparoscopic surgery, also called minimally invasive surgery, bandaid surgery, or keyhole surgery, is a modern surgical technique in which operations are performed far from their location through small incisions elsewhere in the body. There are a number of advantages to the patient with laparoscopic surgery versus the more common, open procedure. Pain and hemorrhaging are reduced due to smaller incisions and recovery times are shorter. The key element in laparoscopic surgery is the use of a laparoscope, a long fiber optic cable system which allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location. There are two types of laparoscope: a telescopic rod lens system, that is usually connected to a video camera, or a digital laparoscope where the charge-coupled device is placed at the end of the laparoscope. Also attached is a fiber optic cable system connected to a 'cold' light source, to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas.
