While there is a large body of evidence on the effectiveness of Pap smears for cervical cancer screening and on screening for cervical gonorrhea and Chlamydia, there is sparse evidence to support other portions of the pelvic examination and little guidance on examination logistics. Maximizing comfort should be the goal; lubrication use and careful speculum selection and insertion can ease this intrusive procedure. This is particularly important in adolescent and menopausal women, sexual minorities, obese women, women with disabilities, and women with a history of trauma or prior instrumentation affecting the genitalia. We review the evidence and provide guidance to minimize physical and psychological discomfort with pelvic examination. P elvic examinations are performed to evaluate pain, bleeding, and vaginal discharge and to screen for cervical cancer and sexually transmitted infections. Little attention has focused on the mechanics of pelvic examination technique, yet the examination is an intrusive experience for many women who feel exposed and lack control. 1 Emotional distress and fear of pain are cited as reasons for reduced adherence to cervical screening especially among adolescents, 2 racial/ethnic 3-5 and sexual minority groups, 6 obese women, 7 victims of sexual assault and other trauma, 8 and women with disabilities. 9 Therefore, examination should be limited to components with proven utility and should be performed with cultural sensitivity and procedural excellence, especially in clinical situations that require particular finesse. Accordingly, we review the clinical evidence as it exists, and in areas that lack evidence offer our own experience to optimize technical aspects of speculum choice and insertion, and suggest strategies to manage challenging circumstances. When recommendations are not referenced, we are relating our experience in the absence of evidence. Bimanual examination is not useful as a screening test for ovarian cancer because of limited sensitivity and specificity. In one study, ovaries were palpable in 55% of women under 200 lbs during examination under anesthesia, but in only 9% of women over 200 lbs. 14 In another study under similar circumstances, uterine size and contour were correctly assessed in over 50% of patients; however, sensitivity of examination for adnexal masses of 5 cm or greater was only 28% among attending gynecologists and 16% among gynecology residents. 15 The USPFTF acknowledges poor performance characteristics of the bimanual examination in its recommendation about screening for ovarian cancer. 11 In the non-screening setting, bimanual examination is inadequate to evaluate acute abdominal pain or vaginal bleeding, 16 since ultrasound is so much more sensitive and specific.
COMPONENTS OF THE FEMALE PELVIC EXAMINATIONThe most evidence-based approach would therefore suggest Pap smear collection alone and the speculum examination required to achieve that goal. We suggest that bimanual and sometimes rectovaginal examinations may be important in evaluating pelvi...
