Patients with gastric cancer are easy to metastasize through blood and liver metastasis occurs. After the occurrence of liver metastasis, there may be no obvious symptoms in the early stage. With the increase of intrahepatic metastasis or the presence of intrahepatic metastasis in some special locations, patients may have some related symptoms. For example, patients may have digestive tract reactions, such as poor appetite, reduced food intake, abdominal distension, etc. At the same time, because the liver metastasis leads to the decline of liver function, the transaminase increases, or the patient shows jaundice. The patient shows yellowing of the mucosa and skin of the whole body.
