Chocolate cysts are a type of endometriosis, which is treated clinically by surgery in the vast majority of cases, with a relatively high recurrence rate after surgery. The vast majority of postoperative chocolate cysts are treated with Daphylline for three or six months, mainly to prevent recurrence. In spite of this, there are recurrences in clinical practice, and most of them occur about a year after stopping the medication, so it is advisable to give regular reviews. And it is recommended that in the case of chocolate cysts, it is better to place the Mannorrhea ring after surgery in married patients, which may avoid the possibility of recurrence. This is because the Mannorrhea can cause the endometrium to appear to shrink so that the ectopic lesion will also have shrinkage.
