Appendiceal cysts are amenable to surgical treatment. Generally speaking, once detected, they should be surgically removed, and then according to the results of the pathologic examination, the next step of the specific surgical method and follow-up measures should be guided. Generally speaking, the cyst itself is a relatively benign lesion, the integrity of the peritoneum must be ensured during resection, and the cyst must be completely removed to avoid rupture, so that the mucus inside the cyst can spread in the abdominal cavity, and if rupture occurs during the operation, the abdominal cavity should be repeatedly rinsed out to avoid the formation of a pseudo-mucinous tumor of the peritoneum. If the pathologic examination suggests malignancy, it is necessary to resect other parts of the intestine, and some of the surrounding lymph nodes should be cleared to remove the lesion completely, and the patient should be treated with intravenous levofloxacin, cefuroxime and other antibiotics after the operation to prevent and control the infection. If the pathological examination is malignant lesions, it is necessary to clear the nearby lymph nodes during the operation, and give 5-FU and other drugs chemotherapy after the operation.
