The liver is one of the most important organs in the human body and has more than 2,000 biological functions. It is known as the “human chemical factory”, and its hidden location and many blood vessels once made it a forbidden area for surgery. After 30-40 years of efforts by surgeons, liver surgery is becoming more and more complete, and the site and size of liver tumor is no longer a contraindication to surgery, that is to say, as long as the patient’s liver function can tolerate the surgical blow, then no matter how huge the tumor is and how dangerous the site of the tumor is during surgery, it can be surgically removed, and the technology is no longer prohibited. The only shortcoming of this traditional surgery is that it is very traumatic and requires an incision of 20-30 cm in the abdominal wall, as well as a complete blockage of all blood vessels entering the liver, which is particularly damaging to the liver function. Modern laparoscopic surgery provides a powerful weapon to solve this problem. Laparoscopic surgery is a new high-tech technique, also known as “micro-invasive” surgery. It generally only opens two to four small 0.5-1.0 cm keyhole-like holes in the abdominal wall, and a 1 cm diameter laparoscope is inserted into the abdominal cavity to magnify the images of the abdominal organs and display them on a TV screen, so that the surgeon can watch the TV screen while inserting tiny instruments through the small holes in the abdominal wall to complete the surgery, thus making it possible to The surgery is completed without the need for a dissection. This technology has been a boon to patients with liver disease. Laparoscopic hepatectomy, pancreatic tumor resection and resection of intra- and extra-hepatic bile duct stones and spleen can be done by simply puncturing 3-4 small holes of 0.5-1.0 in the abdominal wall and using operating instruments, with very little surgical trauma, quick recovery, and greatly reduced hospital stay and medical costs, and with little intraoperative tumor extrusion to reduce the possibility of metastasis. According to our experience, except for tumors in some special parts of the liver, about 80% of liver tumors (including the vast majority of liver giant hemangioma), most of pancreatic body tail tumors resection, and splenectomy for various diseases of the spleen can be performed by minimally invasive surgery. The specimen is put into an impermeable specimen bag, then the bag is taken out through the puncture hole, and the tumor is inactivated by injecting medicinal water into the bag, and then the swelling is carefully removed. With the advancement of technology and the update of instruments, more and more patients with hepatobiliary, pancreatic and splenic portal hypertension can be spared from the pain of “open bowel”. The patient’s postoperative pain is greatly reduced, even for laparoscopic pancreaticoduodenectomy, the patient can be discharged from the hospital as soon as 5 days after surgery, which greatly reduces the hospitalization time and saves a lot of medical resources compared with the conventional “open” method, and recently, the study found that laparoscopic resection of liver malignant tumors is not only minimally invasive, but also has higher long-term surgical effect and cure rate than open surgery. and cure rate is higher than that of open surgery. This minimally invasive technique is mainly suitable for various benign or malignant tumors, intra- and extra-hepatic bile duct stones, and splenomegaly that require liver resection. For patients with hepatocellular carcinoma, arterial chemotherapy pumps can also be left in place to prevent and treat postoperative recurrence.
