The value of two-step operative laparoscopy with interval pituitary suppression in the treatment of infertility caused by severe endometriosis

Abstract

Purpose of review: To appraise a new approach to laparoscopic surgery for infertility caused by advanced endometriosis.

Recent findings: Endometriosis is a common systemic and local disease with altered peritoneal function, which requires both systemic and local treatment. Medication alone cannot improve infertility, and laparoscopic treatment, particularly in severe endometriosis, has a high recurrence rate and is often limited by technical difficulties. Novel treatment strategies have therefore to be sought, especially in women who do not want in-vitro fertilization as a first option, either because they suffer from pain in addition to infertility or want to enhance their fertility over many cycles.

Summary: Two-step operative laparoscopy with interval pituitary suppression by means of gonadotrophin-releasing hormone analogues reduces the extent of endometriosis, as classified by the American Fertility Association, and appears to be a promising method of achieving optimal cytoreduction and facilitating complicated surgery in severe endometriosis, while protecting the ovary from unnecessary trauma. A large-scale well-designed study is needed to confirm that this treatment leads to improved pregnancy rates.
