Laparoscopic radical gastric cancer surgery is a new surgical procedure that has been gradually developed only in recent years. Due to factors such as many vessels supplying the stomach, many anatomical levels, difficult lymphatic clearance and complicated anastomosis, laparoscopic radical gastric cancer surgery is very difficult and technically demanding, and only a few hospitals and a few doctors in China can carry out such surgery. At present, the second ward of general surgery in our hospital has carried out this technology, which is performed by making five small keyhole-like holes of 0.5-1.0 cm in the abdominal wall and inserting a laparoscope of 1 cm in diameter to clearly display the images of the abdominal organs on the TV screen, so that the doctor can watch the TV screen while inserting tiny instruments through the small holes in the abdominal wall to complete the surgery that requires more than 20 cm incision to complete in traditional surgery. Moreover, due to the video magnification of the laparoscope, the gastric lymph nodes can be cleared and eradicated more thoroughly, and the removed tissue is finally removed through a small incision of 3-6 cm. This procedure has the advantages of less trauma, less disturbance of the gastrointestinal tract, less bleeding (basically no blood transfusion is needed), less postoperative pain, faster recovery, smaller incisional scar, and significantly fewer complications.
