Laparoscopic surgery is successfully employed in many general surgery operations particularly in cholecystectomy, inguinal hernia, reflux and gastric hernia, but it is also a preferred surgical method for conditions requiring removal of spleen or adrenal glands or in treatment of colon cancers. Moreover, minimal invasive surgery is increasingly used in neurosurgery, gynecologic surgery, orthopedic surgery, urologic surgery and cardiovascular surgery.
