The incidence of gastrointestinal tumors is increasing year by year with the improvement of people’s living standard, change of lifestyle and dietary habits. After the disease, many patients are afraid of open surgery. Laparoscopic technology allows everyone to experience the benefits of minimally invasive technology. The so-called laparoscopic surgery is to insert a laparoscopic lens with a diameter of about 1 cm into the abdominal cavity through a poke hole in the abdominal wall, so that the organs and lesions in the abdominal cavity are clearly displayed on the TV screen, and the surgeon performs the surgery by watching the TV image, generally only a few 0.5-25px poke holes are made in the abdominal wall, and the surgical instruments are inserted into the abdominal cavity to complete the tumor removal and lymph node dissection. Currently, laparoscopic cholecystectomy has become the “gold standard” procedure for the treatment of gallbladder stones. Laparoscopic radical surgery for gastrointestinal tumors has also gradually become one of the routine procedures for the treatment of malignant tumors of the gastrointestinal tract. Practice has proved that laparoscopic minimally invasive surgery is safe and feasible for the treatment of gastrointestinal malignant tumors and has its unique superiority. However, doctors should strictly grasp the indications for treatment and follow the treatment principles of tumor eradication and safety first. Laparoscopic minimally invasive surgery technology provides a more effective way for the treatment of gastrointestinal tumor diseases. The advantages of laparoscopic surgery mainly include: less tissue trauma and fewer complications. Traditional open surgery requires a certain range of surgical incisions, especially radical surgery for malignant tumors, because lymphatic drainage areas have to be cleared along with the removal of malignant tumor-bearing organs, and adequate exposure is the key to the success of traditional open surgery. Due to the long operation time, large surgical incision and continuous pulling of the incision spreader can easily cause damage to the soft tissues around the incision. These factors make the patient’s wound pain more pronounced after traditional open surgery and complications in the wound healing process more frequent, which affects the patient’s postoperative recovery time. In contrast, minimally invasive laparoscopic surgery only requires poking 4-5 small holes in the abdominal wall and inserting the corresponding instruments for surgery, with no or only a small postoperative incision a few centimeters long (for removal of the surgically excised specimen). Patients have less pronounced postoperative pain, can move early, have fewer wound complications, and recover quickly. The whole process of open surgery is performed in the abdominal cavity, which is more disturbing to the organs and prone to plasma membrane damage to the organs, more surgical bleeding, longer postoperative intestinal paralysis, and higher complication rate of postoperative intestinal adhesions. Minimally invasive laparoscopic surgery is performed in the closed state of the abdominal cavity, and the physician’s hands do not enter the patient’s abdominal cavity, so there is less interference with the organs and very little bleeding, and the gastrointestinal tract recovers quickly after surgery, and complications such as postoperative intestinal adhesions rarely occur. The body’s reaction after laparoscopic surgery is lighter and the postoperative recovery is faster. The results of numerous studies have shown that the postoperative serum adrenocorticotropic hormone levels of laparoscopic patients are significantly lower than those of patients undergoing traditional open surgery, indicating that the surgical trauma stress response of laparoscopic patients is lower than that of patients undergoing traditional open surgery. The study of cellular and humoral immune system also showed that the immune system of laparoscopic surgery patients was significantly less affected than that of traditional open surgery patients. Moreover, laparoscopic surgery has less intraoperative bleeding and most patients do not require blood transfusion during and after surgery, which also reduces the impact of blood transfusion on the patient’s immune system and reduces the potential risk due to blood transfusion. Minimally invasive laparoscopic surgery has the same radical tumor treatment results as conventional surgery. Minimally invasive surgery does not mean a reduced scope of surgery. Due to the magnification of the laparoscope, the ultrasonic knife’s features of coagulation first, cutting later, and minimal thermal damage allow the surgery to be performed in the vicinity of important areas with finer and more thorough debridement; all the tumor-free principles of open surgery must also be strictly followed in laparoscopic surgery. These include: adequate exposure of the surgical field; no contact or squeezing of the tumor; surgical resection with sharp dissection as the main maneuver; continuous and complete resection of the primary lesion and lymphatic metastasis area to ensure adequate margins and lymph node clearance; prioritizing vascular treatment, cutting the vessels at the root and removing the surrounding lymph nodes as much as possible; removal of the specimen in a plastic bag; careful flushing of the surgical field; extraction of the puncture cannula prior to Drain the gas in the abdominal cavity to prevent chimney effect, etc. Whether the tumor-free technique can achieve the requirement of reducing local tumor implantation and metastasis is not only something to be noted in laparoscopic minimally invasive surgery, but traditional open surgery should not be neglected as well. As for the cost of surgery, laparoscopic surgery is twice as much as traditional open surgery, however, the overall cost is not much higher than that of traditional surgical methods due to the fast postoperative recovery, short hospital stay and much lower late medication costs.
