자궁경부암 진단을 위한 질확대경 ( colposcopy ) 의 가치

Abstract

The widespread uae of colposcopy in the evaluation of abnormal cervical cytology has been accompanied by a trend toward decreased utilization of Papanicolaou smears and cone biopsy. But its accuracy is dependent on the criteria determining its limitations and the observer's experience. This study was performed to evaluate the diagnostic accuracy of Papanicolaau smear and eolposcopic finding and to campare these findinga with thase af colposcopically directed biopsy, conization and hysteretomy and to determine the value of endocervical curettage. Nine hundred twenty six patients were evaluated from Jan. 1, 1986 to Dec. 31, 1993 at the cancer detectinn center of the department of obstetrics and gynecology, Yonsei University, College of Medicine. Three major classes were involved in this study ; 662 cases with within normal limit Papanicolaou amears with cervical examination grossly suspicious for cancer, 187 cases with squamous intraepithelial lesion or greater, and 72 caees with reactiue or reparative change. The patients with inveaive rnalignancies of the cervix visihle to the naked eye were not included in this study. The majority of patients(75%) were 31 to 50 years of her age. The colposcopic examination wee deemed unsatisfactory in 45 cases in whom the upper limit, of the transformation zone could not be visualized. There were 881 cases each with a satisfactory colposcopie examination. We obtained the following results.
