Reconstruyendo el esfínter anal para revertir la sobredistensión iatrogénica luego de un descenso anal para la enfermedad de Hirschprung
Topic overview
Técnica quirúrgica innovadora para reconstruir el esfínter anal sobredistendido en pacientes con Hirschsprung post-descenso que presentan incontinencia. Cuatro de seis pacientes mostraron mejoría en continencia y movimientos intestinales voluntarios al año, con manometría confirmando restauración funcional del esfínter.
Key takeaways
- Iatrogenic anal sphincter overdistension post-pullthrough can cause soiling in Hirschsprung patients refractory to standard management.
- Sphincter reconstruction showed objective improvement on 3D anorectal manometry with restored occlusive function in all tested patients.
- Four non-Down syndrome patients improved from median Baylor score 0.75 to 4.5, with voluntary bowel movements restored in three.
- One patient achieved complete continence without antegrade enemas; others gained voluntary control but use intermittent enemas.
- Patients reported improved quality of life including ability to participate in sports and leave home confidently after reconstruction.
