Clinical analyses of endometriosis after conservative surgery

To assess the remission rate and outcome of pregnancy of patients who had moderate and severe ovarian endometriosis after conservative surgery. We also wished to analyze the associated factors of recurrence.

Weconducted retrospective analyses of 199 cases with stage II-IV ovarian endometriosis who had preserved fertility under laparoscopic surgical treatment. Postoperatively, the 199 patients were divided into three groups: 43 cases underwent surgical treatment alone (group A); 47 were given a gonadotropin-releasing hormone agonist (GnRH-α) (group B), and 109 were given mifepristone (group C). Ten cases in group A were infertile, 26 cases in group B, and 38 cases in group C. All patients were followed up for 3 years. This study was approved by the Ethics Committee of Yangpu District Central Hospital.

In groups A, B and C, the remission rate was 58.13%, 70.21% and 60.55% and the difference not significant (P=0.384); Recurrence rates were 27.90%, 12.76% and 24.77%, and the difference between them significant (P<0.05). The recurrence rate in group B was the lowest. The natural pregnancy rate after surgery in the three study groups (untreated, GnRH-α and mifepristone) was 30%, 34.61% and 28.94% but this difference was not significant.

Surgery can improve the symptom remission rate and fertility of patients. Postoperative drug therapy does not improve the chance of pregnancy.
