The main treatment for appendiceal mucinous tumor metastasis to the abdominal cavity is surgical treatment, as well as chemotherapy and adjuvant treatment with intraperitoneal thermal perfusion, according to the different conditions of the patients to choose the most suitable and effective treatment method. 1. Surgery: it is the first choice of treatment for appendiceal mucus cyst, especially complete excision of the mass to avoid rupture of the cyst. The specific surgical method is related to the location, size and adhesion of the cyst to the abdominal organs. 2. Chemotherapy: it is to kill the tumor cells during the growth period through the action of chemotherapy drugs, so as to control the development of the disease, even to achieve the role of cure, and can reduce the recurrence of the tumor, commonly used drugs are fluorouracil tablets and so on. 3. Intraperitoneal heat infusion therapy: generally, hot distilled water is chosen to make tumor cells undergo necrosis through heat circulation. However, it is necessary to control the temperature of heat infusion, not to exceed the physiological temperature of human body, so as not to burn the abdominal organs and cause damage. Abdominal heat infusion has a better effect on malignant tumors, so it can be used after surgical treatment of cancer. In the process of chemotherapy patients may have some adverse reactions nausea, vomiting, hair loss, hyperpigmentation, etc. When the reaction is serious, it should be timely consultation to clarify the cause of the disease, and treatment under the guidance of the doctor.
