Abstract:Endometrioma is the most common type of endometriosis.Laparoscopic excision of cyst is generally accepted as the standard surgical treatment methord.But for those recurrent patients，re-operation is not the first choice.Repeated surgery is likely to cause the further damage to ovarian tissue，and may even cause permanent loss of ovarian function.Medical treatment，ultrasound-guided aspiration or combined with sclerotherapy，as well as conservative/radical surgery should be consider as an alternative treatment option according to age of the patients，severity of the disease and fertility requirements.In a word，on the basis of the principle of initial treatment，individualized treatment and standardized operation are recommended.
