ABSTRACT
OBJECTIVE: To evaluate the therapeutic value of conization using right-angled triangular shape loop cone biopsy excisor in patients with CIN 3 who want preserve the uterus. METHODS: A retrospective review of 64 patients was performed who underwent therapeutic conization for CIN 3 by using right-angled triangular shape loop cone biopsy excisor from January 2000 to August 2005. RESULTS: The mean duration of 64 follow-up patients who had conization for therapeutic purpose was 21.5 months (range 10-68). Their mean age was 41.1 years old and mean parity was 1.7. Two of 64 patients had CIN 3 on exocervix margin. During the followed up period, only one person (1/64) had relapse of CIN 3, hence, a simple hysterectomy was done. CONCLUSION: Right-angled triangular shape loop cone biopsy excisor is more effective than U-shaped loop with low rate of margin positive and recurrent rate in conservative treatment in CIN 3 patients who want to preserve uterus or fertility.
