With the continuous improvement of science and technology and medical level, people have higher and higher requirements for medicine. Medical treatment is not only limited to curing diseases, but also how to reduce complications during treatment, how to make the surgery truly remove only the lesion without damaging or less damaging normal tissues, and how to prevent the occurrence of diseases from the root, which has become a higher pursuit of medical quality today. What is minimally invasive? Minimally invasive surgery includes those elements. Is a small incision always minimally invasive? Minimally invasive surgery is to minimize the patient’s immediate and long-term pain caused by surgery on the premise that the treatment effect is no less than or even better than that of traditional surgery, that is, to choose the appropriate surgical approach and method according to the specific condition and the desire to avoid harm, to reduce the degree of incision damage, to reduce the adverse effects of surgical trauma on the patient, and to achieve the best treatment effect with the least trauma. Minimally invasive is based on the premise of efficacy. The advantages of minimally invasive surgery are less traumatic surgery in the near future, less postoperative pain and faster recovery, and better long-term results than traditional surgery, such as less postoperative complications and higher life treatment. Minimally invasive surgery includes endoscopic techniques, lumpectomy techniques, interventional techniques, etc. Minimally invasive techniques are gradually becoming popular, but there are certain misconceptions in the concept of minimally invasive. One of the misconceptions is that open surgery is invasive or massively invasive, while lumpectomy is minimally invasive. No matter open or lumpectomy, both have the purpose of minimally invasive, but if you don’t master the operation indications, it may become invasive or massively invasive. In open surgery, as long as you choose the appropriate surgical method according to the patient’s condition, the size of the incision is reasonable, the operation is careful and light, and the postoperative recovery is fast, the purpose of minimally invasive is also achieved. If the operation, although the incision is small, the pelvic cavity situation is not explored, the pelvic cavity has adhesions, the degree of adhesions, the adhesions of the tissues can not be clarified, it is bound to violent pulling, blind peeling, bleeding and surrounding tissue damage during the operation. The carbon dioxide pneumoperitoneum and hypercapnia during lumpectomy, the pressure of artificial pneumoperitoneum will have an impact on the respiratory and circulatory system and blood physiological and biochemical aspects, so from the subanalysis of the condition, the choice of the appropriate surgical route is the most important, do not just pursue lumpectomy, improper selection of indications and reluctantly, will make the operation more difficult, the operation time is prolonged, and even open the abdomen in the middle specialties, in this way, the The patient increases the injury and affects the long-term results of the surgery. Misconception two: small incision is minimally invasive surgery Some people promote small incision, that small incision is minimally invasive surgery. Small incision can only say that the damage to the abdominal wall is small, perfect surgery is required from the vision of the exposure and clear, only in such a case to achieve the desired surgical results, and too small incision not only affects the surgical vision, but also increases the difficulty of surgery, easy to lead to accidental injury, but also difficult to completely stop bleeding, unnecessarily prolong the operation time, but cause additional trauma. Too large surgical incision causes large trauma, and the scar of large incision after surgery will add psychological pressure to the patient. Therefore, the size of the incision is not a measure of minimally invasive, but depends on the needs of the condition, and the most suitable for the condition is the best. Myth No. 3: No matter the length of surgery, as long as it is lumpectomy, it is minimally invasive Minimally invasive surgery should have less invasive pain, more stable internal environment status, more accurate surgical results, shorter operation time and better psychological effect. For time, in shopping malls, time is money, in surgery, time is life. Every minute longer is a minute more dangerous. The pressure generated by carbon dioxide and pneumoperitoneum during laparoscopic surgery has certain effects on breathing, circulation, and blood, and the longer the time, the more pronounced these adverse effects will be, and the greater the possibility of adverse outcomes. The length of laparoscopic surgery is related to the technical level of the surgeon and the degree of difficulty of the condition. Therefore, when choosing a surgical method, one must choose according to the condition and also according to one’s technical level, keeping in mind that under the doctor’s scalpel is a person with life.
