Abstract :
Transposition of gracilis muscle around anal canal and conversion of the properties to those suitable for the neoanal sphincter have been carried out using rabbit´s model. The muscle was converted to the fatigue-resistant after long-term electrical stimulation and it could maintain sufficient contraction. Feedback regulation of the neoanal pressure using a new electrical stimulation system was applied to attain the prolonged muscular contraction for keeping continence of neoanal function. The total system including implantable pressure sensor was highly effective for reconstructing the neoanal function
