M H Park, J Y Lee, E S Park, J H Kim
This study was performed to demonstrate efficacy of LLETZ in the treatment of CIN. METHOD: One hundred patients with dysplasia diagonsed by colposcopically -directed punch biopsy underwent the LLETZ from April, 1993 to December, 1997 at Gynecologic department of Il Sin Christian Hospital. RESULTS: The comparison between the diagnosis of punch biopsy and that of LLETZ showed fair agreement with 48%[48/100.table3] of cases. The abnormal lesion was underestimated by punch biopsy in 11% of cases. Of them, severe dysplasia was 2 cases and CIS was 4 cases. As the dysplasia lesion was getting severe, margin involvent rate was increased, but there was no relation to recurrence. The 2 case of 90 fallowed up from 3 months to 12 months were reccured after LLETZ. Complication was few. CONCLUSION: LLETZ allowed more acurate histologic examination of the CIN lesion than punch biopsy and showed good result of treatment without complication.
