KTP/532 laser laparoscopy achieved a 38% pregnancy rate in infertile patients with endometriosis, with cure rates varying by disease stage and significantly reduced by additional infertility factors.

Abstract

To determine the clinical effectiveness of the KTP/532 laser in treating endometriosis-associated infertility and to analyze the impact of additional infertility factors on outcome.Prospective cohort analysis of 74 consecutive patients followed up to 24 months after surgery.Tertiary institutional infertility clinic.Cumulative pregnancy rates (PRs), monthly fecundity rates, monthly probability of pregnancy, crude PRs, and cure rates.Thirty-eight percent (28) of patients conceived with a mean +/- SE time to conception of 7.2 +/- 0.8 months. The cure rates were 74% for the total patient sample, 51% for stage I, 69% for stage II, and 64% for stage III disease. Patients who had a cervical factor (P = 0.05), who underwent intrauterine insemination (P = 0.03), who received human menopausal gonadotropin (P = 0.03), or who had additional infertility factors (P = 0.02) had significantly lower crude PRs. The presence of additional infertility factors (P less than 0.02) and intrafimbrial adhesions (P less than 0.01) had a significant impact on cure rates. In the absence of additional factors, 60% (12) of patients with stage I and II conceived. When additional factors were excluded, the overall cure rate was 80%.The results indicate that the KTP/532 laser is an effective tool for the treatment of endometriosis-related infertility. The high prevalence of subtle adhesions may lend further impetus to operative laparoscopy for stage I and II disease. Additional infertility factors may adversely affect outcome.
