Biofeedback reeducation in gracilis muscle transposition after rectal trauma: a case presentation.
A 20-year-old male patient had a significant rectal trauma and underwent colostomy and subsequent creation of a neosphincter through gracilis muscle transposition. The patient was referred for biofeedback training to learn to use the transplanted gracilis muscle as a substitute for the external anal sphincter, Through a period of 10 weeks, the patient became able to identify this transplanted muscle and to increase the amplitude and duration of contraction as measured by surface electromyography. Further, resting tone of the neosphincter was increased. The patient gained continence with respect to liquid, gaseous, and solid stool within 26 weeks of the first biofeedback muscle training session.
