Minimally invasive treatment is an important concept and development direction of modern surgery, and laparoscopic technology, as an important part of minimally invasive surgery, has been able to replace most of the traditional open surgery to complete the treatment of diseases, and the near and long-term results are far better than the latter, which is regarded as one of the most dazzling surgical advances in the 21st century. So, what exactly is laparoscopy? It is an instrument with a miniature camera. Laparoscopic surgery is surgery performed using a laparoscope and its associated instruments. The operating space is formed through an artificial CO2 pneumoperitoneum, illuminated by a cold light source, and a cylindrical laparoscopic lens (3-10 mm in diameter) is placed into the body cavity, and the images captured by the lens are transmitted to a special monitor through an optical fiber using digital camera technology; the surgeon then analyzes the patient’s condition through the images of the patient’s organs displayed on the monitor screen, and uses chopstick-thin laparoscopic instruments to The surgeon then analyzes and judges the condition through the images of the patient’s organs displayed on the monitor screen, and operates through a “keyhole”-sized channel in the abdominal wall using chopstick-thin lumpectomy instruments. The difference between minimally invasive laparoscopic surgery and traditional open surgery: 1. The integrity of the abdominal wall and the confinement of the abdominal cavity are maximally protected: the organs are not exposed to the air, and parts other than the surgical operation are not unnecessarily disturbed by the operation. 4, incision, ligation, hemostasis relies mainly on electrocoagulation, ultrasound technology to complete, more accurate and safe; 2, the advantages of minimally invasive laparoscopic surgery for urological diseases: 1, small incision: light postoperative pain, no analgesic. 2, fast recovery: laparoscopic surgery is performed in the closed abdominal cavity or retroperitoneum, which is much less traumatic than open surgery. Generally, you can get out of bed on the 2nd postoperative day, which greatly reduces the intensity of family companionship. 3, short hospital stay: laparoscopic surgery generally requires only 2-7 days of hospitalization, compared with an average of 11 days for similar traditional open surgery. 4, abdominal wall cosmetic effect: no open surgery long scar, beautiful. It is more attractive to young people and female patients who love beauty. 5, less abdominal adhesions: open surgery process, surgical instruments, the operator’s operation of the abdominal cavity tissue extrusion, organ exposure in the air, too many sutures and ligatures, are important factors in the occurrence of organ adhesions; and laparoscopic surgery almost no stimulation of the above, postoperative abdominal adhesions greatly reduced, especially through the posterior abdominal access surgery (kidney, adrenal and ureteral surgery, etc.), almost completely able to avoid surgery interference with the abdominal organs. 6, medical cost savings: laparoscopic postoperative drugs less, low cost; patients can return to work in the short term.
