Prospective Comparison of Loop Excision under Colposcopic Guidance versus Vitom Guidance

摘要

Background: Aim of the study was to compare the quality of loop excision using a colposcope with results using the VITOM system. Results compared included cervical volume removed, in-tra- and postoperative complications, and positive resection margins.Methods: A total of 200 patients with histologi-cally confirmed high-grade cervical premalig-nant lesions, persistent atypical cytological results and/or suspicious colposcopic findings, and cytological and histological discrepancies were included in the study. In transformation zone type 1 (Tl) only a superficial cone biopsy was done, in zones type 2 and 3 (T2 and T3) a superficial outside cone biopsy or a deeper inside cone biopsy were done respectively, followed by endo-cervical curettage. Volume of removed tissue, complications, and positive resection margins were compared for the colposcopy and the VITOM groups.
