Effect of mifepristone in the different treatments of endometriosis.

OBJECTIVE: To observe the effect of small-dose mifepristone conservative treatment and laparoscopic combined with mifepristone in the treatment of endometriosis. MATERIALS AND METHODS: Sixty-five endometriosis cases were given small-dose mifepristone conservative treatment and were assessed for the effect of this treatment; 92 cases were randomly divided into control group (taking gestrinone) and observation group (mifepristone), FSH, P, PRL and E2 levels were compared before and after treatment, and pregnancy investigation and each sex hormone level monitoring were followed-up at one year after drug withdrawal. RESULTS: Using mifepristone, FSH, P, E2, and LH levels all significantly changed six months after treatment and recovered 12 months after drug withdrawal; when comparing the pelvic symptoms, endometrial thickness showed that mifepristone was significantly effective (p < 0.01), and the pregnancy rate was 27.69%. Comparing the two groups, none of the total effective rate, pregnancy rate one year of follow-up, and recurrence rates were significantly different; hormone levels in the both groups were significantly decreased or increased (p < 0.05) after treatment. The two groups had no significant difference (p > 0.05), but 12 months after drug withdrawal, in the control group (not in the observation group), LH level was still significantly different (p < 0.05) compared pre-treatment. CONCLUSIONS: In the conservative treatment, mifepristone can safely improve the hormone levels, reduce the thickness of the endometrium, alleviate symptoms. With laparoscopic minimally invasive combined drug therapy, mifepristone has a significant effect, with a more followed-up pregnancy rate, less recurrence, and no drug accumulation side-effects, hence it is worthy of clinical application.
