Small intestinal changes in enterocolitis complicating Hirschsprung's disease
Insights
Hirschsprung's disease can cause severe infant diarrhea due to small bowel damage. Early treatment of enterocolitis, including nutritional support, is crucial for survival.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Neonatology
Background:
- Hirschsprung's disease is a common cause of bowel obstruction in children.
- Untreated enterocolitis, a complication of Hirschsprung's disease, carries significant mortality risk.
Observation:
- Two infants presented with intractable diarrhea of infancy.
- The diarrhea was secondary to Hirschsprung's disease.
Findings:
- Mucosal damage in the small bowel is a key factor.
- Disaccharidase deficiency contributes significantly to the complication.
Implications:
- Prompt management of enterocolitis is vital.
- Parenteral alimentation should be initiated early upon complication detection.
Abstract:
Hirschsprung's disease is one of the more common causes of childhood bowel obstruction. The disease can cause enterocolitis which, untreated, may result in considerable mortality. We describe our evaluation of two infants who suffered from intractable diarrhea of infancy secondary to Hirschsprung's disease. We found that mucosal damage to the small bowel and disaccharidase deficiency are among the most important mechanisms producing this complications. Therefore, management of enterocolitis including parenteral alimentation should proceed as soon as the complication is observed.

Histology of the Small Intestine
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
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.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
