OBJECTIVE: to evaluate the effectiveness of the hygroscopic dilator in the colposcopic examination of the endocervical canal in patients with high-grade lesion in the cytopathology and unsatisfactory colposcopy. METHODS: prospective study, including 62 patients with unsatisfactory colposcopic examination and cytology compatible with high-grade intraepithelial lesion. The patients were submitted to dilation of the endocervical canal by means of a hygroscopic dilator. After dilation, the new colposcopic findings were recorded, and then conization was made through loop electrosurgical excision procedure. The incidence of neoplasic involvement of surgical margins was compared between patients with examinations modified toward satisfactory results and those that remained with unsatisfactory colposcopy. In order to compare the incidence of involved margins and the incidence of residual disease, two retrospective control-groups were used: the GinSat group (n = 35): patients with unsatisfactory colposcopy; GSat group (n = 38): patients with satisfactory colposcopy and endocervical atypy. RESULTS: 80.6% of the cases presented satisfactory colposcopic vision after dilation. 80.4% of those presented disease-free resection margins. The incidence of disease-free resection margins in patients with persistent unsatisfactory colposcopy after dilation was 36.3%. Affected surgical margins occurred in 28% of the group that had undergone dilation, 28.5% of the cases in GinSat group, and 31.5% in the Gsat group. Follow-up showed the incidence of residual disease in 7.5% of the patients under dilation, 28.5% in the GinSat group and 28.9% in the GSat group. CONCLUSION: the use of hygroscopic dilation improved visualization of lesions of difficult access to the colposcopic examination, thus permitting reduction in the percentage of residual neoplasic disease in patients with unsatisfactory colposcopy treated with loop electrosurgical excision procedure.

Purpose: to evaluate the histopathologic results of cone specimens of patients undergoing loop electrosurgical excision procedure (LEEP) and their relationship with the localization of the lesion. Methods: in a retrospective study, 134 clinical reports of patients with abnormal findings of cervical cytology and/or biopsy undergoing LEEP were reviewed. The colposcopic findings were divided into three groups according to the localization of the lesion. Group I (n = 36): patients with ectocervical lesions and fully visible squamocolumnar junction; Group II (n = 50): patients with lesions at the ectocervix and endocervix, and Group III (n = 48): patients with unsatisfactory colposcopy. Results: the mean age in Group I was 33 years and there were 8.3% positive margins. In Group II the mean age was 39 years, with 36% positive margins. Group III had a mean age of 48 years and presented 29.2% positive margins. The percentage of residual disease was 4.2% in Group I, 31.6% in Group II and 35.5% in Group III. Conclusion: patients with lesions at the endocervical canal showed a higher rate of positive margins. Patients with high-grade cervical intraepithelial neoplasia at the endocervical canal and older than 40 years have a greater chance of showing positive margins and residual disease, therefore requiring stricter cytologic and colposcopic follow-up.

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.
