[Clinical efficacy of a new method for LEEP conization with pistol-shaped electroknife]

The aim of this study is to establish clinical efficacy of a new method for LEEP conization of uterine cervix. The study is open, retrospective, performed at Department of General and Oncogynecology - Military Medical Academy (Sofia, Bulgaria) for the duration from 2007 till Mar 2010. The study includes 37 women at age from 19-50 years with proved high grade CIN (included Ca coil uteri in situ) by abrasion or biopsy. Medical history was collected from all patients enrolled in the study as well as gynecological examination and colposcopy was performed to them. A LEEP with short intra venues anesthesia was performed to the patients. An innovation system for LEEP conization and generator for monopolar currency ERBE VIO 300D was used. The follow up visit was performed one month after the treatment procedure and included gynecological examination and colposcopy (positive/negative atypical colposcopy results). The clinical efficacy of the method was evaluated on the base of histological results. The patients whose histological results show negative endocervical margins were accepted for cured. From 37 patients in total with different stage of dysplasia and carcinoma in situ hospitalized at Clinic of surgical gynecology for surgical treatment, in 33 (89%) there are negative endocervical margins. These patients formed the cured group. In four patients (10.8%) were discovered histological evidences for positive endocervical margins. The LEEP was not the final operative procedure for them. They were included in the uncured group. The final results achieved from the study about the efficacy of the used method LEEP has statistical significance (d.f .= 1, X2 = 2.82, p < 0.05). The data shows that the LEEP eliminate completely the affected by malignant process areas of cervix uteri. The LEEP can be used as a common surgical method in the treatment of the women with high stage of pre-carcinoma and carcinoma in situ coli uteri.
