Flying has always been a dream of people, but more than 100 years ago it was almost a dream, a fantasy. In 1903, the Wright brothers flew their own plane, the Aviator 1, on the East Coast at Kitty Hawk Beach. In 1903, the Wright brothers flew their Aviator 1 at Kitty Hawk Beach on the East Coast, starting the first human flight. Today, airplanes have become one of man’s daily means of transportation. No one doubts that man can fly freely like a bird anymore. The progress of mankind began when countless “impossibilities” became possible. Like all new things, a few small holes in the abdominal wall can be used for radical treatment of gastric cancer, and most people thought “how is this possible” a decade ago when the tumor was removed. Since Goh et al. applied laparoscopic technology to radical gastric cancer treatment in 1997, after more than 10 years of accumulation, laparoscopic radical gastric cancer treatment has matured technically. Laparoscopic minimally invasive radical gastric cancer treatment has become a routine procedure in Japan and Korea, countries with high incidence of gastric cancer in Asia, and laparoscopic gastric cancer surgery has been widely performed in the United Kingdom, Italy, Sweden and other countries in Europe. In terms of treatment effect, laparoscopic specialists have been able to reach or even surpass open radical gastric cancer surgery with good results. Laparoscopy and ventral hernia in Xinjiang Autonomous Region People’s Hospital In principle, laparoscopic technology is only a technical means that does not change the principle of surgical treatment. It is the doctor’s hands using some advanced instruments to operate outside the abdominal cavity through the small holes in the abdominal wall instead of traditional open surgery holding ordinary surgical instruments in the abdominal cavity. Laparoscopic radical surgery for gastric cancer is a highly difficult laparoscopic surgery, and the surgeon must not only have rich experience in open surgery, but also have skillful laparoscopic operation techniques. The operation requires only five small keyhole-like holes of 0.5-1.0 cm in the abdominal wall and the insertion of a 1 cm diameter laparoscope, which clearly displays the images of the abdominal organs on the TV screen, and the doctor looks at the TV screen while inserting tiny instruments through the small holes in the abdominal wall to complete the operation that requires more than 20 cm incisions to complete in traditional surgery. Thanks to the video magnification of the laparoscope, the gastric lymph nodes can be cleared more thoroughly, and the removed tissue is finally removed through a small incision of 4 to 6 cm. Laparoscopic surgery for the treatment of gastric cancer is a new international trend in the treatment of gastric cancer in recent years. Compared with traditional surgery to remove gastric cancer, it has many advantages such as less trauma, less disturbance in gastrointestinal tract, less bleeding (basically no blood transfusion is needed), less pain after surgery, faster recovery of patients after surgery, generally patients can get out of bed on the same day after surgery, small incision scar, which does not affect aesthetics, while some patients even dare not swim again after traditional large incision surgery, significantly reduced postoperative complications, and shortened hospitalization time. The total cost of laparoscopic treatment for gastric cancer patients is basically equal to the total cost of open treatment, so that this advanced technology can benefit the majority of gastric cancer patients. Figure 1: Comparison of traditional dissection and minimally invasive laparoscopic exploration for gastric cancer. In order to prevent patients who can be resected from losing the chance of radical treatment for nothing, in the past, we had to perform abdominal dissection (as shown in the picture on the left) to cut an incision of more than 10 centimeters and sew up the tumor directly if it was found that it could not be removed. The patient’s recovery was slow, delaying follow-up treatment, and chemotherapy was usually given only after half a month. In contrast, the application of laparoscopy now only requires 2-3 small holes in the belly (as shown on the right), which can be clearly observed and accurately judged. Patients recover quickly and can have chemotherapy on the 2nd day and be discharged on the 3rd day. Figure 2: Comparison of conventional radical gastric cancer treatment and laparoscopic radical gastric cancer treatment. The advantages of laparoscopic minimally invasive radical gastric cancer treatment are even more obvious. The incision of traditional surgical method reaches more than 20 cm (as shown in the picture on the left), and patients are so painful after surgery that they dare not even cough, and the incision may even crack, and the hospital stay is long, and they can usually be discharged only 10-12 days after surgery. Minimally invasive surgery only requires a few holes plus about 6 cm of incision, and almost no incision dehiscence occurs. Patients recover quickly after surgery and can get out of bed on the same day, and can be discharged from the hospital in 5-6 days after surgery. Figure 3: Laparoscopic lymph node dissection for radical gastric cancer. Laparoscopy has the function of magnification, and even small lymph nodes can be shown very clearly under laparoscopy, and the clearance is more complete. This figure shows the complete clearance of lymph nodes and the process of vascular skeletonization.
