- Abstract:
- Electrically stimulated anal neosphincter formation with transposed gracilis is performed clinically in an increasing number of patients. The use of a stimulated gluteus maximus in this application has been reported also. The question arises whether or not an optimal design for such a procedure has already been ascertained. An anatomic study was performed on 30 human cadavers to evaluate the semitendinosus muscle and its suitability for construction of a stimulated anal neosphincter. Semitendinosus fulfilled requirements for transposition around the anal canal in all cases. The muscle length was found adequate for transposition; nerve and vascular supply provided a suitable arc of rotation. The pattern of innervation might allow selective stimulation of that particular part of the muscle, which is intended to restore sphincter function. For clinical application, a vascular delay procedure is strongly recommended.
