Abstract
OBJECTIVE: To determine how the loop electrosurgical excision procedure (LEEP) compares to cold knife conization in providing an adequate diagnostic specimen. STUDY DESIGN: Between 1991 and 1995, 95 patients underwent either diagnostic LEEP or cold knife conization at Allegheny University Hospitals. The indications for the procedure were a cytologic/histologic discrepancy, unsatisfactory colposcopic evaluation, positive endocervical curettage or exclusion of invasion. RESULTS: Severe thermal artifact rendered the LEEP specimens uninterpretable in 4.4% of cases. A median number of two passes were required for LEEP excision of the transformation zone. The number of passes correlated with the amount of thermal artifact detected (P = .034). Regarding recurrence patterns, normal follow-up cervical cytology was similar for both groups: 96.7% in the LEEP group vs. 100% in the cold knife conization group. CONCLUSION: We conclude that LEEP is an acceptable diagnostic alternative to traditional cold knife conization. Thermal artifact remains a disadvantage that can be minimized by limiting the number of passes required to obtain a complete specimen.
