Minimally invasive surgery, genetic and biological engineering, and organ transplantation are the three main streams of medical development in the 21st century. Laparoscopic surgery is to poke a small hole in the patient’s surgical site, through which a camera and special lengthened surgical instruments are inserted to complete the same steps in open surgery under TV surveillance and achieve the same therapeutic effect. In the past decade, the application of laparoscopy has been regarded as a major development that subverts traditional abdominal surgery. 1, the superiority of laparoscopic surgery (1). Small incisions, 3 – 4 small incisions of 0.5cm – 1.0cm can hardly be seen after healing, while the body wall nerves and muscles are spared from being cut off, the incisions are easy to heal. (2). Small organ interference, fast postoperative recovery: laparoscopic surgery does not need to open the abdominal cavity, less interference with the abdominal organs. Generally speaking, the function of organs in laparoscopic surgery can be recovered about 24 hours earlier than that in open surgery, and the postoperative hospitalization days can be shortened to 1/3~1/2 of the original. (3). Facilitate multi-disease joint treatment: laparoscopic surgery because of the poking port trauma is small and shows the characteristics of flexible and mobile, so the multi-disease patients, especially the pathological foci far apart can be under anesthesia in a full range of exploration, diagnosis and differential diagnosis, and then the joint implementation of laparoscopic surgical treatment, to achieve twice the result with half the effort minimally invasive efficacy. (4). Sharing the same picture, facilitating collaboration: surgeons, instrument nurses, anesthesiologists and other operating room staff can share the same monitor, so that the details of the operation can be seen at a glance, facilitating collaborative surgery and improving the success rate and safety of the operation. 2, the application of laparoscopic technology in abdominal surgery (1) gallbladder stones and biliary tract diseases: laparoscopic cholecystectomy is one of the most widely used laparoscopic surgery, as long as the diseased gallbladder can be removed with 3-4 small incisions of 0.5mm-1.0mm. Cholangiography and choledochotomy can also be performed. This can avoid the huge wound of traditional surgery, reduce the patient’s pain, and the patient can eat and get out of bed one or two days after the operation. (2) Acute abdominal pain and peritonitis: Acute abdominal pain and peritonitis can not be established before the operation of the correct diagnosis, must be carried out to explore the whole abdominal cavity of the situation. The use of laparoscopy can avoid unnecessary caesarean section and wounds, establish the diagnosis of the disease, and remove the lesion. (3) Peptic ulcer: laparoscopic vagotomy or ulcer perforation repair surgery has been successfully used to treat peptic ulcer and its complications, can greatly reduce the patient’s postoperative pain. (4) Intestinal obstruction: Laparoscopy can be used for the localization and diagnosis of intestinal obstruction. Simple intestinal adhesions can be easily treated by laparoscopy. (5) Inguinal hernia: Laparoscopic hernia repair has good therapeutic effect for recurrent hernia and bilateral hernia, and can fully identify the hernia defect site and intra-abdominal organs. (6) Benign tumors of gastrointestinal tract: laparoscopy with intraoperative endoscopy can remove benign tumors of the gastrointestinal tract and do gastrointestinal anastomosis, reducing postoperative pain and accelerating the recovery of patients. (7) Abdominal trauma: for blunt abdominal injuries or puncture wounds. Laparoscopy can provide good assessment and treatment, reducing unnecessary caesarean section. We can find from practical experience, laparoscopic treatment of various surgical diseases with small incisions, trauma, pain, little interference with the organs, to facilitate multi-disease treatment, post-operative recovery, scarring, hospitalization time is short, etc., so many diseases can be avoided to be “cut open”, this minimally invasive technology is also accepted by an increasing number of patients. This minimally invasive technique is also accepted by more and more patients.
