In recent years, with the development of surgical medical technology, people are not only seeking medical treatment for the cure, but more people are considering physical and mental rehabilitation, such as pain during surgery, postoperative scars, etc. In order to minimize the trauma to the patient, laparoscopy is one of the minimally invasive representatives in recent medical history. At present, laparoscopic minimally invasive surgery has been used in gynecology for many years. Although recognized by the majority of female friends, most people are still curious and worried about laparoscopy, and the following are a few questions commonly encountered in the clinic: What diseases can be treated by gynecological laparoscopic minimally invasive surgery? Diagnosis: various difficult diseases, such as acute abdominal pain, chronic pelvic pain, uterine perforation, infertility, dysmenorrhea, etc. Treatment: various types of ectopic pregnancy, conservative treatment of ectopic pregnancy (preservation of fallopian tubes), pelvic adhesions, endometriosis, ovarian endometriosis cysts, benign ovarian teratoma, ovarian cysts, uterine fibroids, various pelvic masses, tubal sterilization, tubal recanalization. Can “keyhole” surgery be complete? Minimally invasive laparoscopic surgery does not require opening the abdomen, and the incision is only about 5mm in size, especially like a keyhole, which is why it is called “keyhole surgery”. However, some patients do not know much about laparoscopy and have some concerns, thinking that “keyhole” surgery is not as intuitive and reliable as open surgery. Laparoscopic surgery is made easier and more reliable by improving the surgical operation method and surgical instruments. Laparoscopic surgery has a clearer field of view, more detailed surgical operation, and less possibility of complications. Currently, legislation has been introduced in the United States and Singapore that makes it illegal for a surgeon to use a “keyhole” procedure in the first place if it causes additional pain to the patient. Can laparoscopic surgery be performed in obese patients for gynecological conditions? Obese patients are better suited for laparoscopic surgery. In obese patients, open surgery can easily cause postoperative incision infection and incisional hernia because of the large and deep incision and the easy liquefaction of subcutaneous fat. In addition, the respiratory function of obese patients is significantly lower than that of those with normal weight, and postoperative complications such as pulmonary infection and pulmonary atelectasis are significantly higher than those with normal weight. If laparoscopic surgery is performed, there is no difference between obese patients and normal weight patients in terms of wound size, duration of surgery, damage to the muscle and incidence of postoperative complications. The incidence of complications such as incisional infection and pulmonary infection is lower in laparoscopic surgery than in open surgery. Therefore, obese patients are more suitable for laparoscopic surgery. How can large pelvic masses (such as uterine fibroids and cysts in the penumbral direction) be removed from the small opening? Many people are surprised by the question, how is it possible to remove such a large mass from a small opening in the abdominal wall? If it is a cystic ovarian mass, the fluid inside the cyst can be sucked out first with a thin puncture needle to shrink the mass and remove it from the small opening in the abdominal wall. In the case of larger solid masses, such as uterine fibroids, the masses can be cut into strips with special instruments and then removed through a small incision in the abdominal wall. All of the above specimens need to be placed in a specimen bag beforehand and removed through a small incision in the abdominal wall. The entire mass can also be removed from the vagina. The large mass is removed without a large scar on the abdominal wall, with only 3 small incisions of about 5 mm, and no trace of the surgery is visible after healing.
