The laparoscope, as currently used in clinical practice, is a medical device with a cold light source as well as a miniature camera. The so-called laparoscopic surgery, in layman’s terms, means that the surgeon inserts a laparoscopic lens (10 mm in diameter) It is inserted into the patient’s abdominal cavity and transmits the intra-abdominal situation to the TV screen in real time, while using slender instruments to perform intra-abdominal surgery through the abdominal puncture hole. It has been proven that for most abdominal diseases, laparoscopic surgery can achieve the same efficacy as open surgery. Further, compared with traditional open surgery, laparoscopic surgery also has the following advantages: 1. Fast postoperative recovery and short hospital stay. Patients can get out of bed early after surgery, which significantly reduces the incidence of postoperative pulmonary embolism, pneumonia, decubitus ulcer and urinary tract infection, promotes the recovery of intestinal motility, and improves the safety of surgery for elderly patients. 2.Small postoperative incision and corresponding complications of incision are reduced. The lumpectomy mostly adopts 2-4 holes operation method. After the patient recovers, only a few 0.5-1 cm linear scars will be left in the abdominal area. Compared with traditional open surgery, laparoscopic surgery incisions are hidden, leaving no obvious scars and local aesthetics. In addition, the damage to the abdominal wall is small, and the incidence of postoperative incisional hernia of the abdominal wall is small. 3, laparoscopic camera with magnification, can clearly display the fine structure of the body tissue, compared with the traditional open surgery, the field of view is clearer, so the operation is more accurate, fine, effectively avoid unnecessary interference with organs outside the operating site, and less intraoperative bleeding, the operation is safer. 4.Little trauma and light postoperative pain. 5, the early postoperative period can be free to turn over, activities, intestinal function recovery, greatly reducing the occurrence of intestinal adhesions, thereby reducing the incidence of adhesional intestinal obstruction after open surgery. 6, although the cost of laparoscopic surgery is more expensive than open surgery, but because it can shorten the number of days patients are hospitalized, the extra cost of surgery can be partly saved from the hospitalization cost. Therefore, the total hospitalization cost of laparoscopic surgery is basically the same as that of open surgery. 7, laparoscopic surgery on the patient’s immune system interference is significantly less than the latter, some immune indicators can be returned to normal earlier after laparoscopic surgery.
