A fiber optic telescope, called a laparoscope, is inserted into the female's abdomen below the navel to look for endometriosis, scarring, adhesions, and other pelvic disease. At times, the procedure is performed to look for the cause of pelvic pain or infertility and is called a "diagnostic" laparoscopy. Once disease is identified, however, the surgeon should be capable of performing an "operative" laparoscopy, and actually treat the disease. Instruments such as a laser can be useful in some cases to treat adhesions and endometriosis. The primary advantages of laparoscopy include rapid patient recovery (because of the extremely small incision) and reduced cost (since the patient nearly always goes home the same day). Aside from the treatment of extremely large fibroids, most pelvic surgery can be performed laparoscopically.
