Laparoscopic surgery is a new surgical operation technique that emerged at the end of the 20th century and developed rapidly at the beginning of the 21st century. Its main operation method is to inject gas into the patient’s abdominal cavity to form a pneumoperitoneum space, and then put in a special mirror and operating instruments through a special orifice. Compared with traditional surgery, laparoscopic surgery has outstanding advantages such as less intraoperative bleeding, less surgical trauma and faster postoperative recovery. It can benefit patients to the maximum extent. At present, laparoscopic surgery has been widely used in many surgical fields, including gastrointestinal surgery, hepatobiliary surgery, urology, gynecology and other related diseases, and the application of laparoscopic surgery has been very extensive and skillful. Malignant tumors, especially gastrointestinal tumors, have become one of the top diseases that endanger people’s lives. After the rapid development in recent years, laparoscopy has been vigorously promoted as a more suitable surgical method for the treatment of colorectal cancer, and has good application prospects in abdominal malignant tumors such as gastric cancer, liver cancer and pancreatic cancer. Among patients suffering from gastrointestinal tumors, most of them are elderly people, and elderly people have poor physical condition and more comorbidities. Minimally invasive laparoscopic surgery can not only achieve the same surgical effect as open surgery, but also complete some operations that cannot be done by open surgery, and minimize the damage to the normal body of elderly people.
