Dark blood in advanced gastric tumor is due to upper gastrointestinal bleeding caused by the tumor. Advanced stage of gastric tumor means advanced stage of gastric cancer. The condition of advanced gastric cancer develops more rapidly and is critical. It will lead to bleeding caused by ulceration of stomach tumor. After bleeding, the blood will enter the intestines with the digestive system and be discharged with stools, which usually causes the symptom of pulling black blood in stools. In the advanced stage of stomach tumor, due to the critical condition and poor physical condition, the time for surgical treatment is often lost, and sometimes radiotherapy and chemotherapy are difficult to bear, and at this time, only palliative treatment can be given. The treatment of patients with advanced gastric cancer should focus on reducing pain and prolonging patient’s life, and they should seek medical treatment in time when adverse symptoms appear. In the advanced stage of gastric tumor and pulling black blood, hemostasis treatment can be performed under gastroscopy; or injection of hemostasis drugs such as hemostasis, tranexamic acid, snake venom hemostasis drugs, thrombin, vitamin K, etc.; or blood transfusion treatment.
