[Incontinence after repair of imperforate anus : treatment by a free muscle transplant (author's transl)].

A case of severe anal incontinence after multiple surgical repairs for ano-rectal imperforation is presented. A successful formation of a new puborectalis sling by means of free autogenous palmaris longus muscle transplantation according to Hakeliuis is reported. The clinical success is confirmed radiologically and electromyographically. The authors discussed the principles and the results of this new method. They believe that this case pleads in favour of true muscle autotransplant re-innervation.
