Abdominal fluid accumulation should belong to stage IV of cancer, which is advanced stage. Abdominal fluid accumulation is often caused by metastasis to the greater omentum or mesentery in the abdominal cavity, which is generally considered to be incapable of radical surgical resection and should belong to advanced stage. If the abdominal distension is serious, ascites can be extracted, and after the ascites is extracted as much as possible, chemotherapeutic drugs such as cisplatin can be injected into the abdominal cavity, and intraperitoneal perfusion chemotherapy can slow down the generation of ascites. At the same time, it is also necessary to combine with the primary site of the tumor to formulate a systemic chemotherapy program, if the ascites is not very serious, a lot of patients do not have abdominal distension and other discomforts can also be considered to carry out systemic chemotherapy first.
