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 blood vessels supplying the stomach, many anatomical levels, difficult lymphatic clearance and complex anastomosis, laparoscopic radical gastric cancer surgery is difficult and technically demanding, and only a few hospitals and a few doctors in China can perform such surgery. This technique 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, while the doctor looks at the TV screen and inserts tiny instruments through the small holes in the abdominal wall to complete the surgery which requires more than 20 cm incision to complete. Moreover, due 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 3 to 6 cm. This surgery has the advantages of less trauma, less disturbance of the gastrointestinal tract, less bleeding (basically no blood transfusion is needed), less postoperative pain, faster postoperative patient recovery, smaller incisional scar, and significantly fewer postoperative complications. In addition, laparoscopic surgery can avoid meaningless or even harmful dissection for patients with advanced gastric cancer. At present, we have fully mastered this technique and have performed laparoscopic radical resection of distal gastric cancer, radical resection of proximal gastric cancer and radical resection of the whole stomach.
