The laparoscope technique does not cut the body wall completely, but introduces the laparoscope through a small hole, and obtains enough space after the laparoscope is inflated and expanded in the abdominal cavity or the thoracic cavity. Under the guidance of the laparoscope, the abdominal cavity of a patient is observed firstly, and meanwhile, a small surgical instrument with a long handle is inserted under the guidance of the laparoscope, so that the operation which is completely the same as the traditional open operation is completed. Currently, substantially all types of conventional open surgery can be performed laparoscopically. The introduction of laparoscopic surgery has the great advantage of enabling faster recovery of the patient, while achieving exactly the same effect as traditional open surgery, with significantly less surgical scarring on the body wall.
