If there is melena in the late stage of liver cancer, gastrointestinal bleeding should be considered first, usually upper gastrointestinal bleeding. At this time, patients must go to the digestive department or hepatobiliary surgery of the hospital in time, and most of them are considered as esophageal variceal bleeding due to liver cirrhosis. This is a very dangerous disease, and patients must pay attention to it. In this case, conservative medical treatment is generally considered, and symptomatic support treatments such as hemostasis, blood transfusion, maintaining water-electrolyte balance and parenteral nutrition are mainly given. Some patients may need to be treated by endoscopic hemostasis or other compression hemostasis methods. I suggest you go to Guangzhou Dafu Cancer Hospital to have a look and standardize the treatment so as not to delay your illness.
