Laparoscopic surgery is the use of laparoscopy and its related instruments to implement the surgery: the use of cold light to provide illumination, the laparoscopic lens (diameter of 3 ~ 10mm) into the abdominal cavity, the use of digital camera technology so that the laparoscopic lens captured images through the fiber-optic fiber conduction to the back-end signal processing system, and real-time display on a special monitor; and then the doctor through the monitor screen to show the patient’s organs in different angles of the image analysis and judgment of the patient’s condition, and the use of special laparoscopic instruments to carry out the operation. Then the doctor analyzes the patient’s condition through the images of different angles of the patient’s organs shown on the monitor screen and performs the surgery with special laparoscopic instruments. Laparoscopic surgery mostly adopts the operation method of 2 to 4 holes (one of which is opened on the navel of the human body), so as to avoid leaving obvious scars in the patient’s abdominal cavity, and after the recovery, there are only 1 to 3 linear scars of 0.5 to 1 centimeter in the abdominal cavity, which can be said to be less invasive and painful, and is therefore also known as the “keyhole” surgery. The development of laparoscopic surgery reduces the pain of incision, shortens the recovery period of patients, and relatively reduces the cost of patients. Laparoscopic minimally invasive at the same time pay more attention to the patient’s psychological, social, physiological (pain), mental outlook, quality of life improvement and rehabilitation, maximize the patient’s thoughtfulness, reduce the patient’s pain. It has the following advantages: both diagnostic and therapeutic role: hysterolaparoscopy can replace most of the transabdominal caesarean section, a typical example is the pelvic inflammatory adhesion masses, due to the use of hysterolaparoscopy, so that the patient and the physician to avoid blind laparotomy, on the other hand, hysterolaparoscopic technology diagnostic at the same time able to carry out surgical treatment, especially in the ectopic pregnancy, rupture of the ovaries, infertility, etc., the disease, its superiority is more obvious. The superiority is even more obvious. Fast postoperative recovery: Hysterolaparoscopic surgery is performed in the closed pelvic and abdominal cavities, and the trauma to the patient is far less than that of transabdominal surgery. In the traditional surgery such as ovarian cysts, ectopic pregnancy and other surgeries in the past, it takes 24 hours for the patient to get out of bed, and the patient needs to use painkillers after surgery, and can only be active for 3-7 days after the surgery, whereas in the case of hysterolaparoscopic surgery, the patient can be out of bed after the surgery, and the vast majority of the patients don’t need to take painkillers, and can be active for 1 day after the surgery, and can be active on average. The majority of patients do not need analgesics, and on average, they can move freely 1 day after the operation, and there is no obstacle to urination and defecation. Reduced hospitalization: no matter how complicated the laparoscopic surgery is, it does not require a long hospital stay, and the average hospital stay is significantly shorter than that of transabdominal surgery. The average hospital stay of our hysterolaparoscopic surgery patients is 5 days, while the average hospital stay of similar transabdominal surgeries is 11 days, which shortens the preoperative hospital stay and accelerates the turnover rate of beds. Cosmetic effect of abdominal wall and less pelvic adhesion: Hysterolaparoscopic surgery only makes 0.5-1.0cm puncture in the umbilical hole and lower abdomen, without the long scar of transabdominal surgery. Comparing with transabdominal surgery, fewer pelvic adhesions occur in patients after hysterolaparoscopic surgery. In transabdominal surgery, the extrusion of tissues by surgical instruments and surgeon’s operation, the exposure of organs to air, and the tendency of excessive intraoperative suturing of the greater omentum and peritoneal adhesion to the trauma are all unavoidable factors for the occurrence of adhesions. In contrast, hysterolaparoscopic surgery has little pelvic interference and no contact with tissues such as gauze or sutures, making postoperative pelvic-abdominal adhesions far fewer than in transabdominal surgery. For some diseases like endometriosis, which are prone to adhesion and recurrence, laparoscopic surgery can be performed several times, and pelvic adhesions are less likely to occur after several abdominal surgeries. Saving medical cost: Hysterolaparoscopic surgery reduces the economic burden of society, units and patients, and the reduction of hospitalization days, quick recovery after surgery, and the reduction of medication all reduce the cost of patients. In addition, due to the minimally invasive surgery, patients can return to work in a short period of time, and the reduction of income due to the disease, and the need for other people to take care of the family, and so on, no longer exists.
