Combination medical and surgical therapy for infertile patients with endometriosis.
Endometriosis is a difficult problem for practicing gynecologists and is commonly associated with infertility. The diagnosis of endometriosis should only be made at the time of laparoscopy or laparotomy and should be confirmed with biopsy if possible. Once the diagnosis is made, it should be classified according to the revised AFS system. The treatment of infertility associated with endometriosis is controversial and usually consists of either medical therapy with hormonal manipulation designed to suppress the disease, surgical therapy designed to debulk the disease and repair anatomic distortion, or a combination of both. Despite an abundance of research on the treatment of endometriosis, the pregnancy rate for patients with endometriosis remains lower than that of the normal population. The reasons for this are obscure. Endometriosis does not respond to hormonal changes the same way that normal endometrium does and has been shown to persist despite extensive medical therapy. The recurrence rate of the disease is impressively high after either medical or surgical therapy. Interestingly, expectant management of minimal or mild disease is associated with pregnancy rates equal to those of any other type of therapy. Only when the disease is more extensive does aggressive treatment appear to show improvement in pregnancy rates. Whether combination therapy of endometriosis is better than single agent therapy remains open to debate. Some of the best-designed studies using combination therapy have shown no difference in pregnancy rates. Yet, when taken as a whole, it would appear that if combination medical and surgical therapy is chosen, the medical therapy should be given preoperatively. The literature abounds with a wide variety of classification systems, methods of calculating pregnancy rates, and inclusion of control groups. Because of this disparity between studies, reliable conclusions cannot be drawn.
