Intraperitoneal infusion chemotherapy is the injection of drugs into the peritoneal cavity for treatment and is one of the most commonly used treatments for local chemotherapy. For patients with intra-abdominal tumors and their tumors metastasized to the peritoneal cavity, peritoneum or metastasized to lymph nodes in the abdominal cavity, intraperitoneal infusion chemotherapy can effectively control metastases on the peritoneum and ascites, and has a certain effect on the control of tumors in the abdominal cavity. The concentration of drugs in intraperitoneal infusion chemotherapy is higher, while the concentration of systemic chemotherapy drugs is lower, so the effect of intraperitoneal infusion chemotherapy on tumor control in the abdominal cavity is more obvious, while the systemic toxic reaction is also less. Therefore, in clinical practice, for patients with large amount of ascites or peritoneal or abdominal metastases, or large tumors in the abdominal cavity, the method of intraperitoneal perfusion is generally used to make the concentration of chemotherapeutic drugs in the abdominal cavity higher, so as to achieve better tumor suppression and lower systemic toxicity, so that patients can easily accept chemotherapy and achieve better efficacy and lower side effects as an effective clinical treatment method.
