MINIMIZING THE RISK OF POSTOPERATIVE PYODERMA-GANGRENOSUM

A 61-year-old woman with seropositive rheumatoid arthritis developed numerous ulcers due to pyoderma gangrenosum at suture entry/exit sites following an arthroplasty of the right hip when interrupted silk sutures were used to close the skin. When a subsequent arthroplasty was performed on the left hip and subcuticular Dexon sutures were used to close the skin only two small ulcers developed. Sixteen cases of pyoderma gangrenosum developing in surgical wounds have previously been reported. We recommend that surgery in patients with a history of pyoderma gangrenosum is performed when the pyoderma is clinically quiescent, and that subcuticular sutures are used for skin closure, thus avoiding puncturing the skin surface.
