Minimally invasive surgery refers to the use of minimal surgical trauma to achieve the same diagnostic and therapeutic goals as traditional surgery. In a broader sense, minimally invasive surgery has always been associated with surgical procedures. For a long time, surgeons have been diligently pursuing “minimally invasive” surgical procedures in order to reduce the damage to the human body. Through the accumulation of long-term surgical experience, the selection of reasonable surgical incisions (e.g., McKinsey’s incision for appendicitis surgery), the scope of organ removal, the standardization of anastomosis techniques, etc. all contain the meaning of minimally invasive. However, limited by the development of science and technology, there is no obvious progress in minimally invasive surgery, and it is difficult for people to intuitively comprehend the meaning of minimally invasive surgery. In March 1987, Phillipe Mouret of France successfully performed cholecystectomy using laparoscopy in human body, which opened a new era in the development of minimally invasive surgery, and laparoscopic surgery has been the most outstanding and typical representative of minimally invasive surgery. Some scholars predict that minimally invasive surgery will be one of the main directions of surgical development in the 21st century. Minimally invasive surgery has been given a new meaning, some people call it modern minimally invasive surgery, referring to the application of contemporary advanced electronic, electrothermal, optical and other equipment and technology, electronic mirror image instead of direct vision of the naked eye, long and thin instruments instead of fingers, and strive to complete the observation, diagnosis, excision and other treatment of lesions in the body, the reconstruction of abnormal tissues and organs under the smallest incision path, the least tissue damage and the lightest stress response of the body. It is characterized by less surgical bleeding, less postoperative pain, faster recovery, smaller wounds, and minimal or no scars. At present, the minimally invasive surgical procedures include: cholecystectomy, appendectomy, hernia repair, bile duct exploration, hepatic cyst windowing, fundoplication for severe reflux esophagitis, elective myringotomy and highly elective myringotomy for gastroduodenal ulcer disease, combined splenopancreatic body caudal resection, giant spleen + flow dissection for cirrhosis portal hypertension, huge incisional hernia repair, adrenal tumor resection, gastric cancer radical resection, colon cancer radical surgery. Radical resection of gastric cancer, radical resection of colon cancer, thyroid surgery, and release of intestinal adhesions. In the last two years, we have carried out partial gastrointestinal resection for obesity and achieved remarkable results after surgery.
