Under the leadership of Prof. Wang Jianping, the president and subject leader, our hospital has successfully carried out laparoscopic resection of colorectal cancer, total colectomy, gallbladder removal, appendectomy, resection of most parts of the stomach, D2 radical surgery for gastric cancer, hernia repair and other surgeries, especially laparoscopic resection of ultra-low rectal cancer, which is a one-year rand martyred sunshine share Xi watched ho roses stirred up with the troubled calabash kowtow na hustling a team Similar to the electrogastroscope, laparoscopy is a type of surgery with a Laparoscopic surgery is a procedure that utilizes a laparoscope and its associated instruments. It is performed by inserting a laparoscopic lens (3-10mm in diameter) into the abdominal cavity, displaying the captured images on a special monitor in real time, and then the doctor analyzes the patient’s condition through the images of the patient’s organs from different angles displayed on the monitor screen, and performs the surgery by using special laparoscopic instruments. Laparoscopic surgery mostly adopts 2-4 holes operation method, one of which is opened on the navel of human body, avoiding leaving long strip-like scars in the abdominal area of the patient, and after the recovery, there are only 1-4 0.5-1 cm linear scars in the abdominal area, with a small trauma and little pain, so it is also known as the “keyhole” surgery. Laparoscopic surgery is the most rapidly developing surgical procedure in recent years, as it reduces the pain of open surgery, speeds up the patient’s recovery, and shortens the hospitalization time by nearly half. Compared with traditional open surgery, laparoscopic surgery has irreplaceable advantages: 1, laparoscopic surgery with the help of camera system, the surgical field is significantly better than the traditional surgery, is truly minimally invasive surgery, surgical trauma is greatly reduced, the surgical process and postoperative recovery is easy, and postoperative pain is significantly reduced. The poke holes in the abdominal wall are small, decentralized and hidden, and do not affect the aesthetics after healing. Infection of the incision or fat liquefaction and splitting of the incision have been unavoidable problems with traditional open surgery. Laparoscopic surgery is the best way to solve this problem, and the rate of poking hole infection or fat liquefaction is far less than the incidence of traditional surgery. 2, laparoscopic surgery poke hole is to expand the instrument into the abdominal cavity, the integrity of the abdominal wall is basically preserved, the abdominal wall poke hole instead of abdominal wall incision, to avoid damage to the abdominal wall muscles, blood vessels and the corresponding nerves, which will not lead to abdominal wall weakness and abdominal wall incisional hernia, will not affect the motor function because of abdominal wall muscle scarring, and will not be cut off because of abdominal wall nerves caused by paralysis of the corresponding skin. 3, laparoscopic surgery on the abdominal cavity organs disturbed small, to avoid the air and air dust bacteria on the abdominal cavity stimulation and pollution. Intraoperative hemostasis is complete, bleeding is minimal, the abdominal cavity is relatively easier to keep clean, greatly reducing the factors of postoperative intestinal adhesions, postoperative intestinal function recovery is fast, the patient eats early after surgery, shortening the hospitalization time by nearly half. 4, laparoscopic surgery without cutting and suturing the abdominal wall, ultrasonic knife and a variety of advanced special instruments greatly reduces bleeding during surgery, surgical trauma is reduced, anesthesia, surgery time is significantly shorter than the traditional surgery, which greatly increases the safety of the operation of difficult and critical patients.
