Modern minimally invasive surgery in gynecology has two main directions: one, cathodic surgery, and the other, lumpectomy. Today, I would like to take this opportunity to give you a brief introduction. By using the principle that the pelvic cavity and vagina are separated by only two layers of mucous membrane and the vagina is connected to the outside world, the vaginal access to the pelvic cavity reduces the interference with the abdominal cavity and the abdominal wound, thus reducing postoperative pain and shortening the postoperative recovery time. At present, the procedure is more often performed in the form of cathartic hysterectomy, and will be gradually carried out in the future to remove myomas or adnexal masses. When it comes to lumpectomy, the scope is even larger. The most common clinical application is laparoscopy. Several small holes are taken in the abdomen, and the “endoscope” and “manipulator” are inserted respectively, so that the abdominal and pelvic cavities can be seen clearly, which can have both diagnostic and therapeutic effects. It is the gold standard for gynecological examination of many diseases and can accurately detect pelvic lesions that cannot be detected by ultrasound or CT, and understand the extent of the lesions. It can also perform a variety of surgeries under direct vision, such as pelvic adhesion decomposition, ovarian cyst removal, adnexal resection, uterine fibroid excision, hysterectomy, etc. It is also one of the important means of infertility examination and treatment, which has the advantages of less tissue damage, less postoperative adhesions, less pain and faster recovery than traditional surgery. In addition to laparoscopy, we also have hysteroscopy. Perhaps you are not familiar with it. Don’t worry, let me introduce it to you. The principle is similar to that of a gastroscope. A tiny “camera” is passed through the cervix and into the uterine cavity, so that the inside of the uterus is visible. A number of cervical lesions, endometrial diseases, post-abortion fetal remnants, angular pregnancies, fibroids protruding into the uterine cavity, congenital malformations of the uterus (e.g., longitudinal uterus), abnormal uterine bleeding, intrauterine devices, etc., can be diagnosed by hysteroscopy. Many of these conditions can also be treated simultaneously, such as removal of cervical or endometrial polyps, removal of submucosal fibroids or longitudinal uterine septum, and removal of an embedded IUD —— thus allowing some patients to avoid open surgery. Combined laparoscopy and hysteroscopy is an important screening and treatment tool for infertility patients today. Their effectiveness has also long been proven. The combined power of laparoscopy and negative surgery is even more powerful. They compensate for each other’s defects and can perform procedures that cannot be done by traditional feminine or laparoscopic surgery, even radical surgery for uterine cancer.
