This is an issue of great concern to everyone. In recent years, more and more women are suffering from ovarian chocolate cysts, because ovarian cysts can lead to female infertility, how to get early diagnosis and treatment is of great importance to the majority of patients. This article introduces the diagnosis and treatment of ovarian chocolate cysts, hoping to help the health of the majority of women. Ovarian coeliac is a lesion of endometriosis. Normally, the endometrium grows in the uterine cavity and is influenced by female hormones in the body, shedding once a month to form menstruation. If the endometrial fragments shed during menstruation enter the pelvis through the fallopian tubes with the menstrual blood reflux and are planted on the surface of the ovaries or other parts of the pelvis to form ectopic cysts, this ectopic endometrium is also influenced by sex hormones and repeatedly shed and bleed with the menstrual cycle. If the lesion occurs on the ovaries, there is local bleeding during each menstrual period, making the ovaries enlarge and forming cysts containing stale blood inside, this stale blood is This old blood is brown, sticky and paste-like, resembling chocolate, so it is also called “chocolate cyst”. Endometriosis is called a gynecological “benign cancer” because of its implantability and incurability, although it is not a tumor. Ovarian chocolate cysts are a type of endometriosis. Ovarian chocolate cysts can involve only one ovary, but in more than 50% of cases, both ovaries are involved. Symptoms of chocolate cysts commonly include dysmenorrhea, lower abdominal pain, and menstrual fever. As the disease progresses, patients may develop progressive dysmenorrhea, persistent lower abdominal pain, menstrual disorders, infertility, and painful intercourse. Smaller ovarian chocolate cysts are usually less likely to rupture. Pharmacological treatment of ovarian chocolate cysts is ineffective and makes it difficult to eliminate the cyst. When the cyst increases to more than 3-5 cm, the risk of spontaneous rupture begins to appear and gradually increases, and once the cyst wall ruptures upon a sudden rise in tension in the cystic cavity, an acute abdomen can develop. Since the blood flowing into the pelvis from a ruptured ovarian chocolate cyst is old and not a large amount of fresh bleeding, it usually does not affect the vital signs and does not cause shock, except for abdominal pain. Some people think that since it is not life-threatening, can conservative treatment without surgery be adopted to save the patient from the pain of surgery. In fact, otherwise, after conservative treatment, the cystic wall rupture heals and the symptoms disappear, but spontaneous rupture may occur again soon. Such repeated attacks can cause serious pelvic adhesions, and the abdominal pain caused by pelvic adhesions can make her “worse” and miserable. Therefore, those who are diagnosed with ovarian chocolate cysts with a diameter of 5 cm or more can be considered for surgery. The surgery is mostly performed by laparoscopic chocolate cyst debridement to preserve the normal ovarian tissue to the maximum extent possible, and postoperative medication is needed to consolidate the effect, which is important to prevent the recurrence of ovarian chocolate cysts.
