Abstract
Our objective was to assess the technical characteristics, side effects, complications, and effectiveness of electrosurgery vs continuous wave CO2 laser in the treatment of genital warts. This open clinical trial was made up of 208 evaluable patients (135 women and 73 men) with vaginal and external anogenital condylomas. To avoid selection bias, in each patient half of the lesions measuring 2 cm2 or greater total linear area were treated with loop electroexcision and ball electrofulguration, and the other half were treated with CO2 laser excision and vaporization in a continuous wave mode spot welding. All patients were followed for at least 6 months (maximum 18 months, mean 8 months) after the last treatment received. The average operative time was 6 min for electrosurgery and 8 min for laser. Healing was completed in 95% of patients with a lesional area of 5 cm2 or less and 100% of patients with 5 cm2 or larger by the third and sixth postoperative week, respectively. Severe discomfort occurred in 12% of patients, and 4% of patients developed delayed complications, including vitiligo and scarring, irrespective of treatment modalities used. Complete clearance of warts in women and men after a single (51% and 38%) and multiple (75% and 64%) treatments were similar in areas treated with electrosurgery and CO2 laser. Electrosurgery appears to be as effective as continuous wave CO2 laser for treating vaginal and external anogenital condylomas, particularly those limited to a 5 cm2 or less area.
