In recent years, as the concept of minimally invasive surgery has gained popularity, cathodic surgery has become increasingly popular. The advantages of using the vagina for surgery include less tissue trauma, less postoperative pain, fewer postoperative complications, and lower medical costs. With the development of medical science, vaginal surgery in line with the principle of “minimally invasive” has gradually emerged around the world. Professor Lang Jinghe of Peking Union Medical College Hospital said that of the three ways to remove the uterus, namely open surgery, laparoscopic surgery and negative surgery, the latter is the most minimally invasive and should be the most preferred. Among gynecological diseases, uterine fibroids and benign ovarian tumors are very common. In the past, surgery for gynecological diseases such as uterine fibroids and benign ovarian tumors has been done through abdominal incisions. However, in recent years, with the gradual strengthening of the concept of minimally invasive surgery, feminine surgery has become increasingly important. Using the natural cavity of the vagina for surgery has many advantages such as less tissue trauma, less interference with abdominal organs, less postoperative pain, fewer postoperative complications and lower medical costs, which is more in line with the principle of minimally invasive surgery and its superiority has been recognized. At present, negative hysterectomy has become the best option for hysterectomy today. 2.Multiple advantages of the negative surgery Compared with traditional surgery, the advantages of negative hysterectomy are very obvious: transvaginal hysterectomy, the peritoneum is opened to the smallest extent, with minimal interference with the intestine and low incidence of postoperative intestinal obstruction; no incision in the abdomen, no scar on the abdominal wall; light postoperative pain, fast recovery, 12 hours after surgery can leave bed and eat, 5 days can be discharged from the hospital, less infection, short rehydration time, low medical costs; elderly patients can be discharged from the hospital after surgery. The medical cost is low; elderly patients, especially those with poor cardiopulmonary function and medical comorbidities, tolerate the negative hysterectomy better. 3.Indications for negative surgery: uterine fibroids, myometriosis, functional uterine bleeding, early endometrial cancer, cervical cancer in situ, uterine prolapse, etc. Commonly used surgical methods include total hysterectomy, subtotal hysterectomy and myomectomy. With its unique advantages, the Yin surgery has been welcomed and recognized by the majority of female patients. It has enabled the majority of female patients to both relieve their pain and retain their perfection.
