The use of the CO 2 dioxide laser in infertility surgery has expanded during the past several years. The results are equal to those of conventional microsurgery, and the CO 2 laser has been associated with bloodless surgery and easy accessibility to deep locations in the pelvic cavity. Tissue healing is good, with a marked reduction in fibrosis, especially with the use of pulsed mode. Recently, the introduction of the waveguide enhanced the use of the CO 2 laser during laparoscopy for treatment of pelvic pathology. The results suggest that laser laparoscopy shortens the recovery period and duration of hospitalization of patients.
