Laparoscopic surgery, also called keyhole surgery (when natural body openings are not used), band aid surgery, or minimally invasive surgery (MIS), is a surgical technique. Medically, laparoscopic surgery refers only to operations within the abdomen or pelvic cavity. Laparoscopic surgery belongs to the field of endoscopy. Only tiny incisions are made for the insertion of an instrument called a laparoscope that transmits images to a video monitor, which the surgeon in turn uses to perform surgery with small instruments that pass through the incisions.
