Abstract
This study examined the use of extended carbon dioxide laser vaporization in 25 women with histologically confirmed, multicentric subclinical papillomavirus infection of the lower genital tract to determine whether carbon dioxide laser can eradicate subclinical papillomavirus infection. An extended carbon dioxide laser procedure involved vaporization of the epithelium of the entire lower genital tract. We performed the procedure under colposcopic guidance. Vaporization was carried out in continuity, to an appropriate tissue depth, while using recommended power densities for the respective target tissue. For sexually active study patients, male consorts were evaluated and treated concurrently to reduce the risk of recurrent infection. Postoperative morbidity was considerable, with moderate to severe vulvar pain and febrile reactions occurring in 100 and 76% of patients, respectively. Histologic persistence of subclinical papillomavirus infection was documented in 88% of study patients at follow-up examination. Neither treatment of the male consort nor sexual abstinence significantly improved treatment outcome. These data suggest that extended carbon dioxide laser procedures cause significant short-term morbidity without effectively eradicating subclinical papillomavirus infection of the female lower genital tract.
