Abstract:
The authors present a neonatal case of allergic colitis, which manifested the difficulty of spontaneous defecation and irregular narrowing of distal rectum in contrast enema. Rectal suction biopsy showed positive acetylcholinesterase activity. These clinical, radiological and histological findings were indistinguishable from Hirschsprung's disease. Gastrointestinal symptoms were improved by the cessation of cow's milk formula. The present findings may impact on the less recognizable gastrointestinal manifestation of allergic colitis.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
