Efficacy of Laparoscopic Surgery Combined with GnRH-a in the Treatment of Endometriosis / 中国微创外科杂志

ABSTRACT

Objective To evaluate the clinical efficacy of laparoscopic surgery combined with GnRH agonist in the treatment of endometriosis. Methods From January 2008 to January 2012, 205 patients with endometriosis underwent conservative laparoscopy surgery in our hospital .According to whether the patients accepted the therapy of GnRH-a and the time of the treatment after surgery, patients were divided into three groups:group A was treated with conservative laparoscopic surgical (73 cases), group B was given GnRH-a for 3 months after surgery (68 cases), and group C received GnRH-a for 6 months after surgery (64 cases).These patients were followed up for 24 months after surgery .The recurrence rate and pregnancy rate were compared among the three groups . Results The postoperative recurrence rates within one year were 4.4%(3/68) in the group B and 3.1% (2/64) in the group C, which were all lower than that of the group A (13.7%, 10/73).There was no difference between the group A and B (χ2 =3.628, P=0.057), while the rate of group C was significantly lower than that of the group A (χ2 =4.771, P=0.029).The cumulative recurrence rates in the group B and C were respectively 13.2%(9/68) and 10.9%(7/64), which were significantly lower than that of the group A [27.4%(20/73); χ2 =4.322, P=0.038; χ2 =5.839, P=0.016].There were no differences about the natural pregnancy rate within 2 years postoperatively among the three groups (χ2 =0.812, P=0.666), but for those who underwent IVF-ET after laparoscopy, the pregnancy rates in group B and C were respectively 78.9% (15/19) and 80.0% (16/20), which were significantly higher than that of the group A [47.6% (10/21); χ2 =4.177, P=0.041; χ2 =4.630, P=0.031]. Conclusions Laparoscopic surgery combined with GnRH-a is highly effective in the treatment of endometriosis , which can effectively reduce the recurrence rate .Application of GnRH-a for 3-6 months after laparoscopic surgery can improve the pregnancy rate in those who accept the treatment of IVF-ET.
