[Efficacy of conservative laparoscopic surgery combined with goserelin in treatment of 206 patients with severe ovarian endometriosis at short-term and long-term follow-up].

Objective To evaluate the short-term and long-term efficacy of conservative laparoscopic surgery combine with goserelin in treatment of severe ovarian endometriosis.Methods From January 2004 to December 2008,206 patients with severe ovarian endometriosis underwent laparoscopy surgery in Nanjing Drum Tower Hospital,Affiliated Nanjing University Medical School were enrolled in this retrospective study.According to the revised classification American Fertility Society (r-AFS), 123( 123/206,59.7％ ) cases were at stage Ⅲ and 83 ( 83/206,40.3％ ) patients were at stage Ⅳ.Among 138 cases presented pelvic pain.All the patients underwent laparoscopic cystectomy,of which 117 patients with childbearing preserving underwent hysteroscopy and hydrotubation examination,including 7 cases with bilateral salpingectomy,2 cases with bilateral tubal obstruction and 108 cases with normal reproduction.After surgery,all cases were administered by goserelin treatment at dose of 3.6 mg per 28 days for 3 to 6 months.At 1 to 5 years following up,pelvic pain,pregnancy and recurrence were observed,those factors associated with pregnancy rate and endometriosis recurrence were analyzed.Results (1)Pelvic pain:complete remission rate of pelvic pain was 76.1％ ( 105/138 ) at 1 to 5 years after surgery.(2) Pregnancy:total pregnancy rate was 70.4％ (76/108),spontaneous pregnancy rate was 68.8％ (66/96) and pregnant rate of in vitro fertilization and embryo transfer (IVF-ET) was 10/12.Pregnancy rate at 1 year was 57.3％( 55/96 ) and accounting for 83.3％ ( 55/66 ) in all pregnant womon.Live birth rates of spontaneous pregnant and IVF-ET were 86.4％ ( 57/66 ) and 9/10,respectively.( 3 ) Recurrence:the total recurrence rate was 8.3％ ( 17/206 ) at 1 to 5 years.The recurrence rates and the cumulative recurrence rates were 3.9％(8/206) and 3.9％ (8/206) at the first year after operation,2.0％ (3/149)and 6.7％ ( 10/149 )at the second year,1.0％ (1/99) and 8.0％ (8/99) at the third year,10.9％ (5/46)and 17.4％ (8/46) at the fourth year,0 and 2/18 at the fifth year,respectively.Conclusion It was suggested that conservative laparoscopic surgery combined with goserelin in treatment of stage Ⅲ or Ⅳ ovarian endometriosis could reduce the recurrence risk of severe ovarian endometriosis and improve the pregnant rate of endometriosisassociated infertility.
