The value of colposcopy in evaluating cervical intraepithelial neoplasia during pregnancy.

Two hundred eighty-three patients with abnormal Papanicolaou smears of the cervix underwent colposcopic examination during pregnancy. Two hundred fifty-six were biopsied and 27 patients were not. Forty-five patients had cone biopsies done during the postpartum period. Despite previous reports which have shown colposcopy as a safe and accurate method of investigating an abnormal Pap smear during pregnancy, this study advocates colposcopy and biopsy as complementary procedures without serious complications.
