Abstract

Perianal fistula is a chronic debilitating disease the treatment of which is complex and the results of treatment often dissatisfactory. Traditional surgical treatment modalities such as fistulectomy or fistulotomy, though effective in the treatment on certain types of fistulas, carry a high risk of anal incontinence. Therefore, safer methods such as autologous fat grafting have been investigated. The treatment results of the procedure are promising. It is a simple, one-step operation that is reproducible and has low complication rate.
