Restoration of fecal continence with chronic electrostimulation of gracilis muscle 17 years after a Pickrell's operation.
A 27-year-old woman who had undergone a Pickrell's operation at the age of 10 years, was observed for severe incontinence to solid and liquid stools. Physical examination and physiological tests revealed poor resting anal tone but a very good response of the transposed gracilis to percutaneous electrostimulation, which showed that the gracilis ability to contract was maintained in spite of 17 years of only occasional and unplanned muscular activity. Examination also demonstrated that the muscle had followed body growth during the patient's development. Restoration of continence by continuous electrostimulation of the gracilis muscle was then planned. To allow muscular resistance to this stimulation a fast-to-slow twitch fiber conversion was first obtained by low-frequency electrostimulation. A subcutaneous abdominal implant of a pulse generator connected to the gracilis by intramuscular platinum-iridium electrodes was carried out. After a period of muscular training, fiber conversion was achieved, and continuous electrostimulation led to complete restoration of continence with stable results at the 36 month follow-up evaluation. This case demonstrates that even such a long period of muscular inactivity does not affect the possibility of recovering a failed Pickrell's operation using electrostimulation. This easy and safe procedure can be applied to all previously failed graciloplasties provided that muscle contractility is maintained.
