For ascites in the late stage of gastric cancer, the nature of ascites should be determined first, and ascites can be extracted through abdominal puncture for cytology and routine ascites biochemical examination. If the patient is judged to be ascites caused by hypoproteinemia, albumin supplementation and diuresis can be given. If the patient has malignant ascites, that is, ascites caused by gastric cancer metastasis to the peritoneum, anti tumor drugs such as bevacizumab, cisplatin, 5-fluorouracil or Chinese patent drugs such as Kanglaite capsule, Aidi injection, sophora flavescens can be injected into the abdominal cavity when the ascites are drained as far as possible.
