Colposcopic evaluation of pregnant patients with abnormal cervical smears.

Colposcopic examination and biopsy were used to assess 123 pregnant patients presenting with abnormal cervical smears. Eighty-seven per cent were 30 years of age or less and 95 (77 per cent) had had one or no previous children. Two patients were found to have microinvasive carcinoma and, in an additional 95 patients, either severe dysplasia or carcinoma in situ was present. Fifty-five patients (45 per cent) had subsequent conization or hysterectomy and in no instance was the histological diagnosis more serious than that anticipated from the colposcopic evaluation. Only three patients (1-6 per cent) had a cone biopsy during pregnancy; only one minor complication occurred. Colposcopic examination is the choice method of evaluating patients with abnormal cervical smears in pregnancy.
