Studies analysing equipment and treatment fields for the presence of HPV DNA
| Study no | Author/year | Study design | Sample size | Findings |
| 1 | Ferenczy 199042 | Treatment fields of patients undergoing CO2 laser ablation of genital warts or CIN lesions were analysed for HPV DNA using a dot blot hybridisation technique. | 43 patients | HPV DNA detected in 34/43 tissue samples and 7/43 laser margins. |
| 2 | Bergbrant 199443 | Surveillance petri dishes placed at a distance of 1 m and 2 m from the treatment field were analysed for the presence of HPV DNA using PCR following multilayer CO2 laser ablation or electrocoagulation of genital warts. | 15 surveillance petri dishes | HPV DNA was detected in 2/15 surveillance petri dishes. |
| 3 | Weyandt 201138 | Surveillance petri dishes placed at a distance of 1 m and 2 m from the treatment field were analysed for the presence of HPV DNA using PCR following multilayer APC or CO2 laser ablation of genital warts. | 66 surveillance petri dishes | HPV DNA corresponding to patient HPV types was detected in 0/66 of the surveillance petri dishes. |
| 4 | Dodhia 201844 | KTP laser fibres were analysed for the presence of HPV DNA using PCR following KTP laser ablation of laryngeal papillomas. | 12 patients | HPV DNA was detected in 0/12 KTP laser fibres. |
APC, argon plasma coagulation; CIN, cervical intraepithelial neoplasia; CO2, carbon dioxide; HPV, human papillomavirus; KTP, potassium titanyl phosphate; LEEP, loop electrosurgical excision procedure; YAG, yttrium-aluminium-garnet.
