LLETZ is indicated when it is considered necessary to remove the transformation zone. Because the technique allows sufficient flexibility to accommodate transformation zones of every site and size, it is inevitable that women who would otherwise
have
had a cone biopsy will now have a LLETZ procedure.
During the early 1990s, the technique of LLETZ has acquired widespread approval throughout many of the colposcopic communities, and its advantages over destructive methods of treatment have been described by several authors.
Sixty three patients with cervical intraepithelial neoplasia diagnosed by colposcopydirected biopsy underwent the LLETZ from January to July, 1995 at the Gynecologic Department of Chonbuk University Hospital.
This study was performed to assess the efficacy of LLETZ in the management of CIN.
1. The age distribution was 44.4% in the 3rd decade, 34.9% in the 4th decade, in which the 3rd and 4th decade took most of the patients distribution.
2. The rate of agreement and underdiagnosis of colpodirected punch biopsy was 77.8% and 7.9% respectively to the result of LLETZ.
3. The overall success rate of LLETZ according to margin positivity was 92.1%. Of the 45 patients with CIN III, only 5 patients were reported with positive margin.
Therefore a single therapy with LLETZ proved effective in 40 patients with CIN III(88.9%).
4. The average width and depth of specimens were 20.5 mm and 14.3 mm respectively.
LLETZ was also able to provide enough and proper specimen for pathologist, because the diameter of thermal injury was less than 0.3 mm .
5. Complications of LLETZ include minor bleeding in 5 patients(7.9%) and major bleeding in 2 patients(3.2%).
Of these patients with cervical bleeding, none needed transfusion, but two patients needed hospital revisitation.
