Evaluation of the relative efficacy of endometrial curettage for diagnosis of endometriosis by the detection of eutopic endometrial nerve fibers

Objective To evaluate endometrial biopsy and curettage in detecting small nerve fibers in eutopic endometrium for diagnosis of endometriosis.Methods Endometrial biopsies and curettings were taken in 65 women with menorrhalgia.Endometrial nerve fibers were immunohistochemically detected using the pan-neuronal marker PGP 9.5.All patients underwent laparoseopie approach.Results The specificity,sensitivity,positive and negative predictive value were 100% of endometrial biopsy and curettings for diagnosis of endometriosis.Condusions Careful endometrial biopsy combined with immunohistochemical staining for nerve fibers may be a reliable means of diagnosing or excluding endometriosis. Key words: Endometriosis; Eutopic endometrium; Nerve fibres
