title: Initial evaluation of the use of the potassium-titanyl-phosphate (KTP/532) laser in gynecologic laparoscopy.
abstract: A new surgical laser, the potassium-titanyl-phosphate 532 nm laser (Laserscope, Santa Clara, CA) has recently become available for investigative procedures in gynecology. This article reports initial investigation of this laser energy at laparoscopy with the use of a flexible fiberoptic delivery system in rabbits and patients with endometriosis. Tissue effects on peritoneal structures of rabbits with laparoscopic firing of this new laser demonstrated the ability to accomplish surface vaporization without bowel perforation or penetration greater than 2 mm. In ten patients with pelvic endometriosis and pain, effective laparoscopic vaporization of implants has been safely accomplished with ease. Early follow-up revealed symptomatic improvement in all patients. This new laser is easy to use laparoscopically, appears safe in early investigations, and effectively reduces early postoperative pain associated with pelvic endometriosis.
