When suffering from endometriosis, ultrasound reveals chocolate cysts on the ovaries, many patients ask if they can be observed, or treated medically, or if the coeliac fluid can be removed by puncture. The current consensus at the Union Hospital and even internationally is that if they have never been treated for endometriosis, have never had surgery, have coeliacs over 4 cm, or have severe dysmenorrhea, or have fertility In patients with evidence of impairment, the preferred treatment for ovarian chocolate cysts remains surgery for the following reasons: 1. Once endometriosis has formed a cyst of a certain size, i.e., a chocolate cyst, drug therapy is not sensitive and it is clinically difficult, if not impossible, to eliminate the cyst through drugs. If you see advertisements or information that there are prescriptions, herbs, or what drug enemas can promise to eliminate chocolate cysts, you must pay attention to screening, but there are indeed patients who say, my cyst is small and disappeared after taking the medicine prescribed by a miracle doctor, then it can be roughly judged that the cyst is in all probability not a chocolate cyst, but a physiological cyst, which is very common in adult women and generally, without any treatment, disappears more than 3-6 months. The cyst will disappear naturally in 3-6 months without any treatment. 2, some patients are afraid of surgery, refusing surgery, unknowingly may “raise” the cyst very large, coarse cysts are not actively treated, very easy to occur around the period of spontaneous rupture, similar to acute abdominal disease, forcing patients to seek emergency medical care, in individual hospitals lacking experience in the treatment of this new type of acute abdominal disease, lack of knowledge, usually for patients Perform a dissection surgery, and at this time, the cysts are mostly accompanied by serious inflammatory reactions, the surgery is not easy to peel the cysts clean, even leading to the complete removal of one side of the ovary, the patient’s loss is relatively large. The diagnosis of chocolate cyst given by the doctor can only be a general diagnosis, not every cyst in the stomach of every patient is a chocolate cyst, it may be a tumor of a worse nature or more harmful to the body and affect the health of the body, surgery, to be able to remove the tumor and pathological examination, which is the only gold standard to confirm the nature of the tumor. 4, coarctation and ovarian endometrioid carcinoma, clear cell carcinoma are closely related, the malignant rate of coarctation is about 1%, surgery can exclude the malignant change of coarctation, or avoid the long night and the change of the nature of the cyst. 5.Surgery can remove the pelvic mass more thoroughly, relieve menstrual pain and improve the quality of life of patients. 6. For patients with infertility problems, the pregnancy rate of patients can be improved after surgery, and most patients can get pregnant naturally six months after surgery. For recurrence of coeliac disease after surgery, if the patient has concerns about reoperation, ultrasound-guided aspiration of the coeliac fluid can be considered, along with medication for endometriosis, to reduce recurrence, basically excluding malignant changes of the coeliac.
