Tubal patency and pelvic adhesions at early second-look laparoscopy following intraabdominal use of the carbon dioxide laser: initial report of the intraabdominal laser study group.
It has been suggested that the carbon dioxide (CO2) laser, by virtue of its hypothetical capabilities for precise incisions, minimization of tissue handling and bleeding, and shortened operating time, may improve the success rate of gynecologic infertility surgery. To assess this hypothesis, a multicenter prospective study was performed to assess tubal patency and adhesion formation at early second-look laparoscopy after intraabdominal laser surgery. Procedures performed included salpingoneostomy, fimbrioplasty, lysis of adhesions, vaporization of endometriosis, and ovarian wedge resection. The results were compared with those of another multicenter prospective study that utilized nonlaser reconstructive pelvic surgery. Use of the CO2 laser was found to result in a greater tubal patency rate at the time of the second-look procedure. Adhesions present at the time of the second-look procedure were reduced from initial presentation at most sites; however, nonlaser infertility surgery appeared to have equal or greater efficacy in the prevention of adhesion formation at most sites. Thus, the CO2 laser does not appear to be a panacea for the treatment of tuboperitoneal causes of infertility. Pregnancy rates following intraabdominal use of the CO2 laser remain to be established.
