Abstract
AbstractBackgroundViral warts are common infectious skin disease induced by human papillomavirus (HPV). Lasers have been used for warts treatment in recent years with variable success rates.ObjectiveThis study aimed to prospectively evaluate combined treatment with Er:YAG laser and long‐pulsed Nd:YAG laser compared to Er:YAG laser for the treatment of recalcitrant warts after one session.Materials and MethodsThis study included 240 lesions from 24 patients. All the lesions were diagnosed clinically as recalcitrant warts after failure of topical treatment and cryotherapy. About 120 lesions underwent a combined therapy of Er:YAG and long‐pulsed (LP) Nd:YAG lasers, and the remaining 120 lesions underwent Er:YAG laser therapy only. The clearance rate was evaluated 5 weeks after and classified by three‐graded evaluation: complete response, partial response and poor response.ResultsThe clearance rate in the combined Er:YAG + LP Nd:YAG lasers group was, statistically significant, higher than that of the Er:YAG laser group (p = 0.008). The complete response rate was 48% (58 of 120 warts) for the Er:YAG +LP Nd:YAG lasers group and only 29% (35 of 120 warts) for the Er:YAG laser group.ConclusionThe combination of Er:YAG and long‐pulsed Nd:YAG lasers is more effective than Er:YAG laser alone in treating recalcitrant warts after single session.
