Evaluation of a new surgical approach for the treatment of clomiphene citrate-resistant infertility in polycystic ovary syndrome: laparoscopic ovarian multi-needle intervention.

Laparoscopic ovarian drilling (LOD) is the accepted second-line treatment for clomiphene citrate-resistant anovulatory infertility in polycystic ovary syndrome (PCOS). Although multiple pregnancy rates are reduced with ovarian drilling procedures, postoperative adhesion formation is a potential complication in up to 85% of the women subjected to laparoscopic destructive ovarian procedures. Our objective was to determine the effectiveness of a new, specially designed laparoscopic device and technique that might enable treatment for patients with anovulatory PCOS with less trauma and fewer postoperative adhesions. Thirty-five infertile clomiphene citrate-resistant women with PCOS were included. Seventeen women underwent laparoscopic ovarian multi-needle intervention (LOMNI), and 18 women received step-up ovulation induction treatment with recombinant follicle-stimulating hormone followed by intrauterine insemination for three cycles. Patients were followed for a period of 6 months after either laparoscopic surgery or the initiation of ovulation induction therapy. Outcome measures were cycle regularity, pregnancy rate, safety, postoperative adhesion formation, and cost effectiveness. There were no significant differences between the two groups in terms of age, body-mass index, duration of infertility, and basal cycle-day 2 hormone levels. Significant improvement in cycle regularity (p <.01) was found after LOMNI. Cumulative pregnancy rates (35.3% in the LOMNI group vs 33.3% in the ovulation induction group) did not differ between the groups. No adverse events following surgery were noted. Moderate ovarian hyperstimulation syndrome and multiple pregnancies occurred in four and two patients, respectively, in the ovulation induction group. Eight nonpregnant women in the LOMNI group underwent repeat laparoscopy at the end of the follow-up period. No adhesion formation attributable to LOMNI was observed in any of those eight women. The cost of LOMNI was significantly (p <.001) lower than the ovulation induction treatment. In conclusion, LOMNI may be a safe, inexpensive, and effective procedure for the treatment of CC-resistant infertility in patients with PCOS. It seems to preserve the beneficial effects and probably omits unwanted effects (such as adhesion formation) of LOD.
