In the outpatient clinic, patients often ask me when they decide to be hospitalized for surgery, “Doctor, can this gallbladder of mine be minimally invasive, and can this liver tumor of mine be minimally invasive cut? What is minimally invasive surgery? Nowadays, when patients talk about minimally invasive surgery, they usually refer to the size of the incision. We found that as long as the gallbladder removal, hernia repair or liver resection is done by laparoscopic drilling, it is minimally invasive surgery as they understand it, while open surgery is a huge trauma surgery. Early minimally invasive surgery, as the name implies, is a tiny trauma surgery. It refers to the use of laparoscopy, thoracoscopy and other modern medical devices and related equipment for surgery. With the development of science and technology, the concept of “minimally invasive” has penetrated into various fields of surgery, and the monitoring system is not only limited to endoscopy, but more interventional methods, such as orthopedics and spine surgery. There are other methods, such as microsurgery, which are widely used in hand surgery. Minimally invasive surgery has been widely used in medicine for less than two decades, and the first laparoscopic cholecystectomy done by chance by a French doctor, Mouret, in 1987 was not expected to mark the birth of a new medical milestone. The concept of minimally invasive was formed because of the advancement of the whole medical model. Minimally invasive surgery focuses more on the improvement and rehabilitation of the patient’s psychological, social, physiological, spiritual outlook and quality of life, and reduces the patient’s pain. Minimally invasive surgery requires only 1-3 small holes of about 1 cm in size in the patient’s body, with small scars, light pain, fast post-operative recovery, short hospital stay, and high bed turnover rate. It reduces the harm, inconvenience and pain caused by traditional surgery. Minimally invasive surgery has the superiority of less trauma, less pain and faster recovery. Is minimally invasive surgery a little less cutting? This is an easy place to give people the wrong impression, but in fact it is not. Take laparoscopic cholecystectomy, except for open abdomen, the operation inside is the same, the steps are the same, the route of the removed tissues is the same, and in terms of safety even many gallbladders laparoscopy can hardly help, such as Mirriz syndrome, complex adhesions in the abdominal cavity, frozen gallbladder and atrophic gallbladder. At this point, if forced to go laparoscopically, there is a great risk, and intermediate open surgery becomes the best option, making full use of the exposure and hand touch and all other skills of open surgery has absolute advantages. Complete resection of the tumor and maximum preservation of normal tissues is the philosophy of oncologic surgery. We will try to preserve as much normal liver tissue as possible if we can cut less during liver tumor surgery, but this is all based on strict justification, with standards that are internationally recognized. If it is said that less tissue is cut, but it will make the risk of postoperative recurrence higher, obviously the loss is not worth the gain! Choice of surgical approach In pursuit of the so-called minimally invasive and unable to operate delicately by hand, conservative operations are often chosen in order to avoid surgical accidents. In some cases even risky operations are not obtainable and there are often great risks. It has been studied that the rate of bile duct injury after laparoscopic cholecystectomy is substantially higher than before due to the widespread implementation of laparoscopic cholecystectomy, and it does not decrease with the increase of the surgeon’s seniority, which shows that there may be a problem that the surgery that was not suitable for laparoscopic cholecystectomy is also kidnapped at the request of the patients because of the superstition of minimally invasive. This may be a problem in that procedures that are not suitable for laparoscopic cholecystectomy are being kidnapped at the request of patients because of a superstition for minimally invasive surgery. Surgeons understand that some areas are dangerous, and at this time they should not be haphazard in any way, but should extend the incision reasonably, all with safety as the first priority. This safety is both for the safety of the surgery at the time and for the long-term well-being of the patient.
