Abstract
Human papillomavirus (HPV) infections are the most common sexually transmitted diseases leading to genital warts. Developing lesions start off as small papules, which then grow larger and protrude, eventually coalescing into plaque-like formations. The aim of this study was to evaluate the efficacy of diode laser coagulation as a treatment for genital warts relative to their number, size, localisation, and recurrence rate. Altogether, 45 patients were evaluated in this study. Patients were initially assigned to one of two groups, depending on the size and number of their genital warts, and received a maximum of two laser treatments. Patients were assessed up to three months after intervention. A cure was defined as the complete removal of condylomata. In Group I, 84% of the patients (21/25) were free of recurrence after three months (last follow-up visit). In Group II, 60% of the patients were free of recurrence after three months (12/20 patients); 25% after the first and 35% after the second treatment. Overall, a cure rate of 73% was achieved (33/45 patients). By splitting the laser treatment for multiple, extensive, and/or coalescing genital warts into two sessions, thereby being less destructive to the surrounding tissue, it was possible to achieve comparable cure rates between the two groups. This study indicates that laser treatment is an effective therapy option. Further studies including larger patient cohorts are necessary to ultimately confirm the advantages of laser treatment.
