Abstract

This study reports on 108 infertile patients with endometriosis diagnosed at laparoscopy. Sixty-four patients had endometriosis and adhesions vaporized with a CO2 laser (LAS) and were prospectively compared with a control group (CON) of 44 patients who had laparoscopy. The 6- and 12-month estimated cumulative pregnancy rates for LAS were 0.32 +/- 0.07 and 0.55 +/- 0.09 respectively, and for CON 0.17 +/- 0.06 and 0.43 +/- 0.09 (Breslow P = 0.10). Monthly fecundity rates were 6.7% in LAS and 4.5% in CON. Survival analysis with fixed covariates showed that pregnancy rates were increased in patients with adhesions (P = 0.002) and other pelvic disease (P = 0.0001). Pregnancy rates were reduced by age (P = 0.02), previous adhesiolysis (P = 0.0000) and post-laparoscopy medical treatment (P = 0.0002). Our findings indicate that CO2 laser laparoscopy vaporization of endometriosis can be a safe, effective, and possibly improved modality for treating endometriosis.
