Diagnostic strategies for endometriosis: CNGOF-HAS Endometriosis Guidelines

In this chapter we have examined the possibilities of screening endometriosis, both in the general population as well as in the target population. We then proposed decision trees, for primary and secondary care. Currently, there is not enough data in the literature to develop or organize a screening test for endometriosis. Screening for endometriosis is not recommended in the general population (level A). There is also no evidence to support systematic screening in a population with genetic risk factors (endometriosis in a relative), or with other clinical risk factors (increased menstrual volume, short cycles, early menarche) (level A). However, it is possible to propose a decision tree for the management of chronic pelvic pain symptoms (dysmenorrhea, dyspareunia, non-menstrual pelvic pain). The search for symptoms suggestive of endometriosis (intense dysmenorrhea [visual analogue scale > 7/10, frequent abstention, resistance to level 1 analgesics], infertility) should be systematic. The search for localizing symptoms of deep endometriosis (deep dyspareunia, cyclic defecation pain, cyclic urinary signs) enables to orient the patient to second line evaluation. We propose a decision tree for second and third line evaluations, according to the suspicion and/or the discovery of deep lesions with specific locations, or the suspicion of superficial lesions.
