There are many abdominal tumors, including stomach cancer, colorectal cancer, gallbladder cancer, pancreatic head cancer, bile duct cancer and so on. For patients with abdominal tumors, in principle, if there is no contraindication to surgery, no distant metastasis, and no infiltration to large blood vessels and other tissues, surgery is still considered in such cases. Radical resection is preferred. If there is infiltration or adhesion of surrounding organs, combined organ resection can be considered if necessary, for example, for patients with gastric cancer, radical resection or total gastrectomy is often used. For patients with gallbladder cancer, laparoscopic cholecystectomy can be performed in early stage. For progressive gallbladder cancer, wedge resection of the liver, as well as lymph node dissection in the liver and duodenum and skeletonization are also required. For patients with pancreatic head cancer, a pancreatic head duodenectomy needs to be considered. At present, these can be managed by laparoscopic surgery in large medical centers. At present, the most widely promoted procedure is laparoscopic radical surgery for colon cancer, which is not only minimally invasive, but also has better results and faster recovery compared with open surgery. For patients after abdominal tumor surgery, further radiotherapy, chemotherapy and gene targeting therapy should be decided according to the general condition, type of pathology and regional lymph node metastasis in order to improve the survival of patients and reduce early recurrence and metastasis.
