4. WHAT SHOULD THE PHYSICAL EXAM ENTAIL?
“An abdominal exam and a pelvic exam are essential in evaluating pain in a woman when endometriosis is suspected,” says Dr. Giudice. “Sometimes the latter is challenging in young teens and can be deferred.” Overall, however, “the pelvic exam can give insight into pain triggers, adnexal masses (possible endometriomas), and mobility of pelvic organs. A rectovaginal exam is important in evaluating deep infiltrating disease and to gauge the pelvic pain landscape overall. In addition, palpating the pelvic floor musculature is important to distinguish pelvic floor muscle spasm from endometriosis pain.”
“The challenge for clinicians is to think beyond the endometrial implants, taking into account multiple factors that influence pain perception,” says Dr. Stratton. During the examination, the clinician should begin by mapping the regions of pain in the abdomen and back, “distinguishing musculoskeletal pain from deep pain. Determining whether pains are focused or diffuse is also important.”
Dr. Stratton recommends that the routine pelvic exam be modified because a standard bimanual exam “confuses pain signals from the pelvic floor, abdominal wall, bladder, and other viscera. For this reason, a pain-oriented assessment is mandatory.”
Begin with a single digital examination to map tender areas, Dr. Stratton advises. Then consider the size, shape, and mobility of reproductive and pelvic organs. “A bimanual exam will help identify adnexal masses like endometriomas,” she says.
Endometriomas usually are not associated with pain, she adds, but “they are associated with deep infiltrating lesions. Nodularity along the uterosacral ligaments, limited reproductive organ mobility, and thickening of the rectovaginal septum also suggest deep infiltrating lesions. Importantly, deep infiltrating lesions are the lesion type most associated with pain.”18,19
