[Evaluation of endometriosis fertility index in follow-up treatment of endometriosis combined with infertility patients after laparoscopic surgery].

To explore the application of endometriosis fertility index (EFI) in guidance after laparoscopic surgery of endometriosis patients combined with infertility and to explore methods to improve pregnancy rate in different EFI groups. A prospective research was done in endometriosis patients combined with infertility in Beijing Obstetrics and Gynecology Hospital from January 2010 to June 2011, after laparoscopic surgery, these 146 patients were divided into 3 groups by EFI score. Using different pregnancy guidance, these patients had 5 years follow-up. (1) The 5 years overall pregnancy rate was 89.0% (130/146). The pregnancy rate was 95.7% (45/47) in EFI≥9 group, 92.8% (77/83) in EFI 5-8 group and 8/16 in EFI≤4 group, three groups were all reach satisfactory pregnancy rate; the rate of the first two groups had no statistically significance (0.498), but had significant difference with the last group (0.01). (2) In EFI≥5 patients, pregnancy rate was the highest in 6 months after operation; in EFI≥9 group, the pregnancy rate was 66.7% (30/45), and EFI 5-8 group was 50.6% (39/77). (3) EFI≥9 group had the highest natural pregnancy rate [83.6% (46/55)], natural pregnancy rate was significant statistical different in different EFI groups (0.001). EFI score is a useful evaluation in predicting and guiding pregnancy in endometriosis patients combined with infertility after laparoscopic surgery. EFI score guidance, strict post-operation management and positive pregnancy scheme could significantly improve the pregnancy rate of endometriosis patients with infertility.
