We report a preliminary experience concerning the post-operative assessment of three patients who underwent gracilis neosphincter operation for severe fecal incontinence and were studied by computed tomography and anal endosonography soon after gracilis transposition and later after 6-8 weeks of neuromuscular training. Morphologic assessment was correlated with physiologic testing (manometry). Continence was satisfactorily improved in all patients. Both imaging techniques demonstrated the anatomy of the transposed muscle. Computed tomography also assessed lead placement onto the gracilis nerve root and the completeness of muscle transposition around the anal canal. Anal endosonography provided a more accurate assessment of the relation between the neosphincter and residual external sphincter.
