  • Title: [Treatment of insufficiency of the anal sphincter by sacral spinal nerve stimulation with implantable neurostimulators].
    Author: Matzel KE, Stadelmaier U, Hohenfellner M, Hohenberger W.
    Journal: Langenbecks Arch Chir Suppl Kongressbd; 1998; 115():494-7. PubMed ID: 9931666.
    Abstract:
    The feasibility of permanent electrostimulation of the sacral spinal nerves was studied in patients with fecal incontinence and no detectable morphological lesions and thus not amenable to conventional surgical management. Applying acute percutaneous stimulation with needle electrodes, the most relevant sacral spinal nerve for striated sphincter muscle function was identified (sacral spinal nerve S3 or S4). The therapeutic potential of stimulation was tested by subchronic stimulation with temporary wire electrodes and, if effective, permanent electrodes were implanted in four patients. Long-term sacral spinal nerve stimulation persistently improved anal continence and increased the function of the striated muscular anal sphincter.
