We have been performing laparoscopic techniques for 20 years, which is the earliest in Beijing and even in China, so we often answer many questions about laparoscopic techniques at work or on the Internet, so today we will talk about some knowledge of laparoscopic techniques. The concept of “laparoscopy” was first introduced in the early 20th century as an effective adjunct to the diagnosis and treatment of abdominal diseases. Although its value was studied by specialized institutions, laparoscopy still had no place in the field of surgery. It was in 1986 that the first laparoscopic cholecystectomy was successfully performed by hepatobiliary surgeons. This new surgical approach to gallbladder stones caused a tremendous response in the surgical community, and with the establishment of laparoscopic cholecystectomy as the gold standard for gallbladder stone treatment, surgeons soon applied laparoscopic techniques to more areas of abdominal surgery. Laparoscopic systems include endoscopic imaging systems and surgical operating instrument systems. Advanced endoscopic imaging systems can provide surgeons with a clearer view than traditional open surgery, creating more favorable prerequisites for more detailed surgery. At the same time, the endoscopic exposure reduces unnecessary abdominal wall incisions and trauma, and is the basis for rapid postoperative patient recovery. Naturally, endoscopic surgery requires different operating instruments than ordinary surgery, and requires surgeons with more delicate and special operating skills, so laparoscopic surgeons need special training and exercises. The development of laparoscopic equipment in China is relatively late compared to foreign countries, but the introduction and development of laparoscopic technology is still at the same time as foreign countries. We introduced laparoscopic equipment and carried out laparoscopic cholecystectomy in the early 1990s. After nearly 20 years of development, laparoscopic techniques have now been applied to many areas of abdominal surgery. Examples include laparoscopic openings for liver cysts, resection of tumors in the gastrointestinal tract, partial hepatectomy, bile duct surgery, etc. Laparoscopic technology has developed rapidly because of its minimally invasive features, fast postoperative recovery and low pain for patients. With the rapid development of science and technology, it is believed that the development of laparoscopic technology will be faster and will be more widely used in the treatment of more diseases.
