Using cytology to evaluate the endocervical canal after loop excision.
OBJECTIVE
This study assesses cytology to evaluate the endocervical canal immediately after loop excision.


METHODS
In 103 patients, we performed a cytologic smear and endocervical curettage immediately after loop excision. Diagnoses were made independently by two cytopathologists and compared to histology. Diagnostic agreement was evaluated statistically.


RESULTS
Cytopathologist "A" found a sensitivity of 1.0, specificity of 0.9, positive predictive value (PPV) of 0.44 and negative predictive value (NPV) of 1.0. Cytopathologist "B" found a sensitivity of 0.88, specificity of 0.78, PPV of 0.3 and NPV of 0.98. There was good agreement between the two cytopathologists (kappa = 0.42, 95% CI = 0.25, 0.60). Twenty-five endocervical curettage specimens were insufficient for diagnosis. Seven and 4 cytology specimens were judged unsatisfactory by each cytopathologist, respectively. Histologic and cytologic evaluation charges were $283 and $60.50 per patient, respectively.


CONCLUSIONS
The use of cytology efficiently evaluates the endocervical canal after loop excision.
