Why do you want to keep the liquid after hot perfusion?

Leakage phenomenon. After thermal perfusion, 500 ~ 1000 ml of liquid medicine was left in the abdominal cavity, which caused pressure in the body cavity and leakage often occurred around the puncture point. There is no liquid left after hot perfusion, so there is no pressure in the body cavity and no leakage around the puncture point. Thermoperfusion chemotherapy is a new therapy combining hyperthermia and chemotherapy to treat tumors. Its basic principle is to use the difference of temperature tolerance between tumor cells and normal cells to treat peritoneal implantation and metastasis of tumors.
