Abstract

Pulsed-dye laser (PDL) surgery is a recognized treatment of viral warts. Initial studies in 1993 by Tan et al achieved a 72% cure rate for 39 patients after a mean of 1.68 treatments. Since then, conflicting response rates ranging from 47-95% have been reported. The records of 44 patients, who attended the Laser Unit at St. James's Hospital between January 1999 to June 2000, were reviewed. Follow-up was conducted by telephone interview or questionnaire. Twenty-eight (64%) patients identified for the study responded. The average number of treatments was 4 (range 1-12) and mean treatment intervals were 4.9 weeks (3-10). Our results showed 64% complete clearance of all the areas treated, and 46% complete clearance of the 13 areas identified as recalcitrant. Rates for complete clearance varied with anatomic site: 73% for the face, 68% for the hands, and 40% for feet. Seventy-eight percent (7/9) of periungal warts completely cleared, and 70% (7/10) mosaic warts cleared. Twenty-five percent of the patients complained of severe pain during treatment. Post-operative complications were few, and rarely affected the patients' lifestyle. The recurrence of warts, in weeks to months following the last treatment, was reported by 36% of the patients. Seventy-nine percent of patients were satisfied with the treatment they were given. PDL may be useful in treatment of refractory warts in selected patient populations. The study identified a need to address pain control in a significant number of patients.
