Complex intestinal innervation defects, including aganglionosis and dysganglionosis, can occur together. Early diagnosis and thorough biopsies are crucial for effective treatment in children with suspected bowel motility disorders.

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Developmental Biology

Background:

  • Hirschsprung disease, characterized by aganglionosis, is a primary cause of congenital intestinal obstruction.
  • Intestinal neuronal dysplasia (IND) represents a spectrum of enteric nervous system abnormalities.
  • Complex innervation defects can present atypically, challenging standard diagnostic paradigms.

Observation:

  • A case report details a patient with aganglionosis of the distal colon, dysganglionosis in the transverse colon, and extreme hypoganglionosis in the ascending colon and ileum.
  • The ileum exhibited a transition zone with hypoganglionosis and intestinal neuronal dysplasia (IND) type B.
  • The observed pattern of innervation defects suggests a potential link to pre- and perinatal perfusion deficits influenced by colonic vascular anatomy.

Findings:

  • The study highlights that different forms of dysganglionosis can coexist within the same patient.
  • The classical "continuum" of aganglionosis to hypoganglionosis may not always be present.
  • Extreme hypoganglionosis, with absent ganglionic cells, was noted in the ascending colon and distal ileum.

Implications:

  • Early and accurate diagnosis of complex intestinal innervation defects is essential to prevent delayed treatment and multiple surgeries.
  • In pediatric patients with recurrent (sub)ileus post-resection, thorough exclusion of additional dysganglionosis (IND, hypoganglionosis) via full-thickness biopsies is recommended.
  • This case underscores the importance of considering comprehensive small and large bowel evaluations in complex pediatric gastrointestinal motility disorders.
