Objective: To investigated whether persistence or recurrence of cervical intraepithelial neoplasis (CIN) is associated with an involved excisional margin during loop electrosurgical excision procedure (LEEP).

Methods: The records of 256 consecutive LEEP were studied. After LEEP, all patients were followed up by colposcopy and cytology at 4 to 6 month intervals for at least two years. A patient was classified as having persistent disease if SIL was seen within one year of treatment or recurrent disease if SIL was detected after one year of treatment. All relevant patient details including cytology, colposcopy findings, treatment histology, complications, recurrence or persistence of disease entered into a computer database.

Results: Complications occurred in 8 patients (3.1%). LEEP was successful in treating 226 patients (95.4)%. Eleven patients (4.6%) had persistent SIL. Involvement of the resection margin was a significant risk factor for persistent disease (3.1% for uninvolved margins vs 11.4% for involved margins, P < 0.05). Similarly, recurrent disease occurred in 9.1% of patients with involved resection margins vs 2.1% with uninvolved margins (P < 0.05). Eleven patients (4.3%) had microinvasive carcinoma. Only 3 were identified by colposcopy and directed biopsy.

Conclusion: LEEP is established as a safe and efficacious method for the treatment of CIN, long term morbidity including the effect on subsequent fertility must be observed.
