[ Abstract]Objective To investigate the effect of two-tage skin grafting with artificial dermis for perianal hidradenitis suppurativa. Methods A total of 20 cases diagnosed as perianal hidradenitis suppu-rativa in our hospital were selected from 2011 to 2013. In the first-stage operation,all diseased skin inclu-ding the superficial subcutaneous fatty tissue was excised,and normal deep subcutaneous fatty tissue was preserved. Then,artificial dermis was grafted to the preserved fatty tissue. After two weeks,split-hickness skin grafts were used for the skin defects as the second-tage operation. Graft success,recurrence and post-operative appearance were evaluated in these patients who were followed up for 9 to 28 months. Results Skin grafts of all 19 patients were successfully survived. The recurrence of hidradenitis suppurativa oc-curred in only one patient. This patient was treated with reoperation and the postoperative appearance was welly recovered. Conclusion Two-tage skin grafting with artificial dermis appears to be a good treatment option for perianal hidradenitis suppurativa.
