Abstract: Endometriosis is a common disease in women of reproductive age. The laparoscopic treatment is reliable and effective. However, the frustrating problem is the high rate of recurrence after surgery. The mechanism of recurrence, as well as those risk factors, is still unclear. It may be related to the retrograde menstruation, the estrogen-dependent mechanism and the ectopic endometial stem cells. There are many risk factors of recurrence after surgery, the key factor being whether to operate thoroughly. Thus，for reducing the postoperative recurrence, we should not rely too much on postoperative auxiliary drug therapy. We should eliminate the residual lesions as far as possible with respect to the surgery safety.

Key words: Endometriosis, Recurrence, Risk factors, Postoperative period
