Abstract
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, intra- and postoperative complications, and positive resection margins. Methods: A total of 200 patients with histologically confirmed high-grade cervical premalignant 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 (T1) 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 endocervical curettage. Volume of removed tissue, complications, and positive resection margins were compared for the colposcopy and the VITOM groups. Findings: Demographic and reproductive features were similar between groups. In the VITOM group 49 % of patients had zone T1, 30 % had zone T2, and 21 % had zone T3. In the group of patients managed by colposcopy, 48, 45, and 7 % of patients had zone T1, T2 and T3 zone, respectively (p < 0.01). A "top hat" procedure was done in 65 % of patients in the VITOM group and in 38 % of patients in the colposcopy group (p < 0.05). Mean volume of removed cervical tissue measured was similar, with 1.2 cm3 measured in the VITOM group and 1.14 cm3 in the colposcopy group (p > 0.05). There were no significant differences in the type of procedure or the mean volume of removed tissue. Results were similar for both groups with respect to positive resection margins and complications. Conclusion: VITOM is a safe and reliable system. Results using the VITOM system are comparable to those obtained with conventional colposcopy. The potential advantage of VITOM is the broader availability of endoscopic systems in the operating theatre.
