Endometriosis: Diagnosis and Management

Objective: To improve the understanding of endometriosis and to provide evidence-based guidelines for the diagnosis and management of endometriosis. Outcomes: Outcomes evaluated include the impact of the medical and surgical management of endometriosis on women's experience of morbidity and infertility. Methods: Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise along with general gynaecology background. The committee reviewed all available evidence in the English and French medical literature and available data from a survey of Canadian women. Recommendations were established as consensus statements. The final document was reviewed and approved by the Executive and Council of the SOGC. Results: This document provides a summary of up-to-date evidence regarding diagnosis, investigations, and medical and surgical management of endometriosis. The resulting recommendations may be adapted by individual health care workers when serving women with this condition. Conclusions: Endometriosis is a common and sometimes debilitating condition for women of reproductive age. A multidisciplinary approach involving a combination of lifestyle modifications, medications, and allied health services should be used to limit the impact of this condition on activities of daily living and fertility. In some circumstances surgery is required to confirm the diagnosis and provide therapy to achieve the desired goal of pain relief or improved fecundity. Women who find an acceptable management strategy for this condition may have an improved quality of life or attain their goal of successful pregnancy. Evidence: Medline and Cochrane databases were searched for articles in English and French on subjects related to endometriosis, pelvic pain, and infertility from January 1999 to October 2009 in order to prepare a Canadian consensus guideline on the management of endometriosis. Values: The quality of evidence was rated with use of the criteria described by the Canadian Task Force on Preventive Health Care. Recommendations for practice were ranked according to the method described by the Task Force. See Table 1. Benefits, harms, and costs: Implementation of the guideline recommendations will improve the care of women with pain and infertility associated with endometriosis.
