    Purpose: to evaluate the incidence of thermal damage to the specimens excised through large loop excision of the transformation zone (LLETZ) and to determine qualitatively and quantitatively the thermal injury to the ectocervical and endocervical epithelia as well as the influence of the menstrual phase on such process. Methods: we performed a prospective study of 100 patients with high-grade squamous intraepithelial lesions (HGSIL). Thermal damage was subdivided into three grades according to Messing et al¹. Results: thermal injury occurred in all the cases, however, through statistical analysis we found that in 91% of the cases it was insignificant, thus leading to a precise histological evaluation, hence to measure the thermal injury was unnecessary. The grade and extent of thermal damage in excised specimens using LLETZ had no relation to the menstrual phase. The extension of thermal tissue alteration in the endocervical epithelia was 271,6 mu while the extension in ectocervical epithelia was 254,8 mu, showing that the extension of thermal damage is significantly higher in endocervical epithelia. Of the one hundred patients, 80 were in menacme and 20 in menopause correlating the grade and extension of thermal damage with the menstrual state. Conclusion: there was no significant difference in both qualitative and quantitative evaluations. There is no need to measure the thermal damage.

    Depth of glandular crypts and its involvement in squamous intraepithelial cervical neoplasia submitted to large loop excision of transformation zone (LLETZ)

    Background: The authors aimed to confirm the depth of six mm in order to achieve an optimal eradication of the lesion. Materials and Methods: This is a retrospective observational study of 94 cervical surgical pieces from women aged 17 to 22 years with a cytocolpo-histopathological diagnosis of high-grade squamous cervical intraepithelial neoplasia (CIN II and/or CIN III) submitted to large loop excision of transformation zone (LLETZ). The glandular crypts and margins, both exposed or not to CIN, were assessed. The compromise and the maximum depth of the glandular crypts were noticed. Results: After LLETZ, 23 (24.47%) cases presented a neoplasic impairment of endocervical margin and ten (10.64%) of the ectocervical margin. The largest noticed crypt measured 4.500 mm and the shortest 0.100 mm, with an average of 2.148 mm.-Conclusions: Squamous CIN more frequently show the exposure of surgical margins to LLETZ. The deeper location of glandular crypts in the cases studied was 4.500 mm, while the largest neoplastic extension was 3.000 mm The therapeutic method depends on this knowledge.
