The value of endocervical curettage as part of the standard colposcopic evaluation.

: Whether to perform endocervical curettage (ECC) as part of a routine colposcopic examination in patients with an abnormal Papanicolaou smear remains controversial. Some studies consider ECC an essential part of a colposcopic examination regardless of the level of the squamocolumnar junction (SCJ); others consider it superfluous in cases where the SCJ can be visualized. Between January 1980 and December 1982, 278 new patients with abnormal Papanicolaou smears underwent colposcopy. Directed biopsies established the degree of cervical intraepithelial neoplasia (CIN) and ruled out invasive disease. ECC was done on every patient. A total of 51 patients (18%) had a positive ECC. Seven patients could not be evaluated because their records were incomplete. Of the 44 evaluable patients, 32 (73%) had satisfactory colposcopy. In the remaining 12 (27%) the upper limit of the transformation zone could not be seen clearly; in that group the degrees of CIN on colposcopic biopsy and ECC were in agreement in two cases; ECC revealed the degree to be less severe in four cases and more severe in six (50%). In the group with satisfactory examinations, 15 had the same degree of CIN on colposcopic biopsy and ECC; ten had less severe and seven (22%), more severe degrees of CIN on ECC. Of greatest clinical importance was that, overall, 11.5% had a positive ECC despite a satisfactory colposcopic examination. This study indicated that ECC provides unique and important information, justifying its inclusion as part of the standard evaluation of every patient undergoing colposcopy for abnormal cervical cytology.
