Gynecologic laparoscopy, with the improvement of surgical level and medical equipment, has been widely used in the management of benign gynecologic diseases such as endometriosis, ectopic pregnancy, pelvic inflammatory masses, ovarian cysts, etc., from the 1960s to 1970s, with diagnostic laparoscopy and laparoscopic electrocoagulation sterilization, gradually. The application of laparoscopy in the field of gynecology has shown good prospects and its safety has received wide attention. Minimally invasive laparoscopy also pays more attention to the improvement and rehabilitation of patients’ psychological, social, physiological (pain), spirituality and quality of life, with maximum consideration for patients and reduction of their pain. It has the following advantages: 1, both diagnostic and therapeutic role: hysteroscopy can replace most of the transabdominal dissection, a typical example is the pelvic inflammatory adhesion mass, because of the use of hysteroscopy, so that patients and physicians to avoid blind open surgery, on the other hand, hysteroscopy technology diagnosis at the same time can carry out surgical treatment, especially in ectopic pregnancy, ovarian rupture, infertility and other diseases The superiority is more obvious in ectopic pregnancy, ovarian rupture and infertility. 2, the patient’s recovery is fast: hysterolaparoscopic surgery is performed in the closed pelvic and abdominal cavity, the patient’s trauma is much smaller than that of transabdominal surgery, in the previous traditional surgery such as ovarian cyst, ectopic pregnancy, etc., the patient needs 24 hours to get out of bed and needs analgesics after surgery, and can move freely only 3-7 days after surgery, but in hysterolaparoscopic surgery, the patient can get out of bed after surgery, and most patients do not need to take analgesics, On average, patients can move freely 1 day after surgery, and there is no obstacle to urination and defecation. 3.Reduced hospitalization days: No matter how complicated the hysterolaparoscopic surgery is, it does not require long hospitalization time, and the average hospitalization day is significantly shorter than that of transabdominal surgery. The average hospital stay of patients undergoing hysterolaparoscopic surgery in our department is 5 days, while the average hospital stay for similar transabdominal surgery is 11 days, which shortens the preoperative hospital stay and accelerates the bed turnover rate. 4. Less cosmetic effect of abdominal wall and pelvic adhesions: hysterolaparoscopic surgery only involves 0.5-1.0 cm puncture in the umbilicus and lower abdomen, without the long scar of transabdominal surgery. Compared with transabdominal surgery, pelvic adhesions occur less in patients after hysterolaparoscopic surgery. In transabdominal surgery, surgical instruments, tissue compression by the operator, exposure of organs to air, excessive intraoperative suturing of the greater omentum and the tendency of the peritoneum to adhere to the wound surface are all inevitable factors for adhesions to occur. In contrast, hysterolaparoscopic surgery causes less disturbance to the pelvic cavity and no contact with tissues such as gauze or sutures, making postoperative pelvic and abdominal adhesions far less than in transabdominal surgery. For some diseases like endometriosis, which are prone to adhesions and recurrence, hysteroscopic surgery can be performed several times, and pelvic adhesions after multiple transabdominal surgeries are less likely to occur. 5, save medical costs: hysteroscopic surgery makes the society, units, the patient’s three economic burden is reduced, the reduction of hospital days, fast postoperative recovery, the reduction of medication, the patient’s costs are reduced, in addition, because of the surgery microtrauma, the patient can resume work in the short term, and because of the disease brought about by the reduction of income, the family needs to be cared for by others and other problems do not exist.
