Ovarian cysts refer to cystic tumors of the ovary, including physiological cysts, follicles, benign and malignant ovarian tumors. Different surgical methods are adopted for different cases. The specific methods are as follows:1. follicles: surgery is not necessary; 2. physiological cysts: below 5 cm can be observed for their occurrence and development, physiological cysts can disappear on their own without surgery; 3. benign and malignant ovarian tumors: surgery is required. Benign ovarian cysts have a simpler surgical approach, and lumpectomy for ovarian cyst debulking is sufficient, which is usually non-recurring, non-metastatic and has good treatment effect. Ovarian mucinous cysts are benign tumors and need to be completely debulked surgically without fragmentation or omission, as rupture may cause extensive intra-abdominal implantation and metastasis.
