Minimally invasive techniques have been applied to most types of general surgery in the last 5 years, and many experienced laparoscopic surgeons have attempted to perform all the procedures that have been done in open surgery, even some very complex procedures such as pancreatic resection or lobectomy of the liver. It has the advantage of being less locally invasive, among other things. Minimally invasive laparoscopic surgery is less locally traumatic, mainly in terms of: i. Small incision. Second, the hand does not enter the abdominal cavity can reduce the damage to the organ peritoneum and the interference with the organ function, and the postoperative gastrointestinal function recovers quickly with less intra-abdominal adhesions. Third, laparotomy requires a bloodless surgical environment, and the principle is bloodless surgery. Fourth, the operation time is shortened. V. Light systemic reaction. Sixth, quick recovery of organ function. In recent years, general surgery has widely carried out various types of minimally invasive laparoscopic surgery, and its treatment of diseases while minimizing additional damage has set off a boom in minimally invasive technology, improving the quality of life of patients and providing obvious economic and social benefits. Several types of minimally invasive laparoscopic surgeries have been successfully performed, including laparoscopic cholecystectomy, open window drainage of liver cyst, appendectomy, repair of gastrointestinal perforation and exploration, diagnosis and treatment of acute abdomen have been widely used in clinical practice, laparoscopic radical surgery for colorectal cancer, scarless laparoscopic thyroid surgery in the neck has also been performed in clinical practice, laparoscopic radical surgery for gastric cancer, laparoscopic bariatric surgery or type 2 diabetes mellitus and splenectomy will be carried out soon.
