Abstract
Medical records of 154 patients who were diagnosed and treated as cervical intraepithelial neoplasia at the Department of Obstetrics and Gynecology, Dongsan Medical Center, Keimyung-University during the period of January, 1982 to June, 1986 were reviewed, and many factors related to diagonosis were analyzed. The results were as follows: 1. Of the 71 patients who had a hysterectomy following a punch biopsy without intermediate cone biposy. 48 cases (67.6%) showed identical results with the initial diagnosis and 23 cases (32.4%) were underdiagnosed. 2. Of the 45 causes of naked eye conization with hysterectomy, 42 cases(93.3%) showed accurate diagnosis and 3 cases(6.6%) were underdiagnosed. 3. 26 cases oi" colposcopically directed cone biopsy with hysterectomy showed identical results in all cases. 4. 01' the 26 cases of colposcopically directed punch biopsy, 23 cases(88.5%) showed identical results and of the 22 cases of cervical intraepithelial neoplasia, 3 cases had microinvasion but no cases of invasive carcinoma were found. 5. 01' the 139 cases of cervical intraepithelial neoplasia, 17 cases had false negative results in cytology, Above results indicated that colposcopically directed punch biopsy is needed for accurate diagnosis of cervical intraepithelial neoplasia. Performing conization, where colposcopy is used, the size of cone is adopted to the precision, so cases of residual tumor could be minimized. On the other hand, colposcopically directed punch biopsy cou]d reduce the incidence of conization.
