Case in brief
A 17-year-old male with Hirschsprung disease and total colonic aganglionosis, treated with a Duhamel pull-through in infancy, developed recurrent fecal soiling and constipation. Examination showed stool retention despite preserved perianal sensation and sphincter tone, supporting retentive fecal incontinence. After eight sessions of biofeedback therapy, his Revised Fecal Incontinence Score improved from 16/20 to 1/20, and his symptoms resolved.
What made this case unusual
The report describes biofeedback therapy for retentive fecal incontinence in an adolescent with total colonic aganglionosis after a Duhamel pull-through, with complete symptom resolution.
Diagnostic / clinical pearl
In a post-Duhamel patient with soiling and constipation, stool retention with preserved perianal sensation and sphincter tone can support retentive fecal incontinence rather than loss of continence from impaired sensation or tone.
