The concept of minimally invasive: the use of surgical methods that are less traumatic than conventional surgery while achieving the same results as conventional surgery. Trauma includes both physical and psychological aspects. It is also important to consider whether it is financially affordable. Minimally invasive currently seems to be laparoscopic or hysteroscopic surgery, but the high cost of said procedures is beyond the reach of many patients. The cathodic procedure is an ancient procedure that pioneered gynecological surgery because Western medicine was just becoming a science in the 19th century. At a time when anesthesia, sterilization, and antibiotics had not yet been invented, cutting open the patient’s abdominal cavity meant death. At that time, the mortality rate of open surgery was over 70%, so it was forbidden to operate on patients openly. Transvaginal surgery, on the other hand, had a mortality rate of 5%, which was much lower than that of open surgery. After the development of minimally invasive surgery such as laparoscopy, gynecologists found that although laparoscopy was minimally invasive, there were still small perforations in the abdominal wall and the higher cost of laparoscopy made it unacceptable for some patients, so the exploration of gynecologic negative surgery began again. Hysterectomy is the most common gynecologic procedure, with 600,000 cases performed annually in the United States. Hysterectomy can treat a variety of conditions such as fibroids, adenomyosis, early endometrial cancer and cervical cancer. In some cases, such as severe anemia due to adenomyosis or fibroids, hysterectomy is an effective treatment. The three current routes of hysterectomy are transabdominal, transabdominal, and transvaginal. Of these, transabdominal is the most common because it solves all problems, but causes the most damage. Indications for negative hysterectomy: uterine fibroids up to 16 weeks of gestation that do not require preservation of the uterus (including the cervix); early cervical cancer or CIN; early endometrial cancer; uterine adenosis. Contraindications: Severe pelvic adhesions, especially endometriosis. Laparoscopic exploration is required in patients who have undergone surgery or have a history of chronic pelvic pain. If the adhesions are not severe, laparoscopic separation of the adhesions can be done followed by a cathartic hysterectomy. If severe or malignant tumor is possible, conversion to open surgery is indicated. There is nothing to lose if the patient is referred for open surgery. Vaginitis and pelvic inflammatory disease are not under control. The most common complication of a vaginal procedure is infection because the vagina is a relatively bacterial environment. Therefore, vaginal douching with medication at least 3 days prior to surgery ensures that the vagina is relatively sterile. Ms. J, 41 years old, was admitted to the hospital 7 days ago for surgery due to uterine fibroids found for 7 months, heavy menstrual flow and anaemia; the largest fibroid was 6 cm in diameter on ultrasound; she underwent an intraoperative hysterectomy 6 days ago, during which the uterus was removed weighing 535 g. She recovered well after the surgery, got out of bed on the second day and ate a liquid food; only the first and second days she had painful abdominal cramps, which disappeared on the third day. Ms. J is very happy and is about to be discharged from the hospital. I perform more than ten cases of negative gynecological surgery every week, and I am satisfied with the results. It is important to prevent postoperative infections due to intraoperative contamination. Adequate vaginal disinfection three days before surgery is very important. There were two cases of postoperative fever, which was normal after two days of antimicrobial treatment. Then some people ask why such a good procedure is not widely performed. The reasons are: for one thing, cunnilingus surgery relies heavily on the surgeon’s surgical skills, which require long practice to acquire, and for another, it is not as intuitive as other procedures and cannot be easily taught and learned.
