Analysis on the Effect of Radiofrequency Ablation and Electrocautery in the Treatment of Vaginal Intraepithelial Neoplasia

Figure 1

Comparison of pre and posttreatment colposcopy findings between two groups (magnification × 7.5, integrated photoelectric system, Leisegang, Germany). Preoperative electrocautery (a, b) showed local thick vinegar white epithelium by colposcopy as well as uneven staining by the iodine test; thin vinegar white epithelium was still observed by postoperative colposcopy, and the iodine test showed was slightly uneven staining (a', b'). Preoperative radiofrequency ablation (c, d) indicated local thick vinegar white epithelium by colposcopy and uneven staining by the iodine test; the postoperative colposcopy did not show obvious vinegar white epithelium, and the iodine test showed uniform staining (c', d').
