Insights

Transmural healing (TH) in pediatric Crohn's disease (CD) improves outcomes, reducing hospitalizations and complications compared to no healing. While TH offers benefits over mucosal healing (MH), the additional advantage is limited.

Area of Science:

  • Pediatric Gastroenterology
  • Inflammatory Bowel Disease Research
  • Advanced Imaging in IBD

Background:

  • Limited data exist on long-term benefits of transmural healing (TH) in pediatric Crohn's disease (CD).
  • Understanding healing depth is crucial for optimizing treatment strategies in pediatric CD.

Purpose of the Study:

  • To evaluate and compare clinical outcomes in pediatric CD patients achieving TH versus mucosal healing (MH) or no healing (NH).

Main Methods:

  • Retrospective, single-center study of 93 pediatric CD patients.
  • Utilized MRE, ileocolonoscopy, and capsule endoscopy for healing assessment (TH, MH, NH).
  • Assessed outcomes including hospitalizations, surgeries, treatment escalation, and complications at 6, 12, and 24 months.

Main Results:

  • TH and MH groups showed reduced treatment escalation risk versus NH.
  • TH group demonstrated significantly lower hospitalization and complication rates compared to NH.
  • No significant outcome differences were found between TH and MH groups; surgery risk was similar across all groups.

Conclusions:

  • Achieving TH in pediatric CD improves outcomes, though the added benefit over MH alone is minimal.
  • Persistent inflammation in pediatric CD is linked to poorer long-term outcomes.
  • Deeper healing assessment may refine prognostic understanding in pediatric CD.
