A new method is presented for the treatment of anal incontinence in children, including free autogenous muscle transplantation. The primary step is denervation of a skeletal muscle, which 2 wk later is transplanted and placed as a U-sling around the rectum, imitating the position and function of the puborectalis muscle. The transplant is placed in close contact with innervated muscles, which act as reinnervation sources. The results in five consecutive patients are highly promising. An early sign of improvement is the occurrence of a sensation of rectal fullness. All the patients reached an acceptable degree of continence, including abandonment of the use of napkins, 4-12 mo after surgery.
