Low risk of contamination with human papilloma virus during treatment of condylomata acuminata with multilayer argon plasma coagulation and CO₂ laser ablation.
Multilayer argon plasma coagulation (APC) is a new effective method for the treatment of genital warts. We assessed the generation of aerosols containing human papilloma virus (HPV) DNA during treatment of genital warts with multilayer APC and with CO₂ laser ablation. Surveillance petri dishes, swabs from the glasses and nasolabial folds of the operating physician, and swabs taken from the suction units used during CO₂ laser ablation were tested by HPV PCR. HPV DNA corresponding to patient derived HPV types of genital warts was not found in any of the petri dishes and swabs obtained during APC treatment. HPV DNA was detected in none of the petri dishes obtained during CO₂ laser treatment, but in suction filters. In conclusion, both CO₂ laser ablation with plume suction and APC treatment seem to have a low risk of HPV contamination of the operation room.
