Potential of cervical electrosurgical excision procedure for diagnosis and treatment of cervical intraepithelial neoplasia.

The aim of this study was to evaluate the diagnostic potential, treatment efficacy, specimen adequacy, and acute complication rate associated with electrosurgical excision procedure (EEP) of the cervix for the management of cervical intraepithelial neoplasia (CIN). Analysis was performed retrospectively on 153 consecutive patients who underwent EEP under colposcopic guidance. Patients with negative endocervical curettage (ECC), adequate colposcopy, and biopsy-proven CIN were considered candidates for therapeutic EEP, whereas patients with a positive ECC, inadequate colposcopy, or cytology two or more grades discordant from the biopsy results underwent diagnostic EEP. Histopathologic specimens were graded as adequate, suboptimal, or inadequate. Diagnostic EEP was performed in 85 cases, and the remaining 68 procedures were performed primarily for treatment. Specimens were graded as adequate in 83%, suboptimal in 13%, and inadequate in 4% of the diagnostic EEP's. Specimen adequacy correlated most strongly with operator experience (P < 0.05). Four patients were found to have microinvasive or invasive cervical carcinoma. Complications occurred in 7% of the EEPs performed. Most consisted of immediate or delayed hemorrhage. In conclusion, EEP is a safe, well-tolerated procedure which is acceptable as both a therapeutic and diagnostic tool in the management of CIN when performed by an experienced operator. We recommend that initial EEP procedures should be performed for therapeutic indications, since adequacy of EEP specimens correlated with the level of operator experience.
