Topic Overview

Complex case of total colonic aganglionosis presenting with delayed meconium passage, complicated by intestinal malrotation and multiple congenital bands. Faculty discuss surgical management including timing of definitive repair, with preference for Duhamel procedure once ileostomy output consistency improves on solid feeds.

Key Takeaways

  • Total colonic aganglionosis with malrotation is extremely rare; persistent obstruction post-Ladd procedure warrants Hirschsprung evaluation.
  • Duhamel procedure is preferred for total colonic Hirschsprung's, providing a small reservoir and simpler technique than alternatives.
  • Timing of definitive pull-through should be based on ileostomy output consistency (firming with solid food), not age or weight alone.
  • Multiple congenital bands can coexist with malrotation and Hirschsprung's, requiring careful intraoperative assessment and release.
  • Infants with total colonic aganglionosis require specialized nutrition (high-calorie formula, vitamin B12) and close monitoring for dehydration.
