Clinical and radiological diagnosis of Crohn's disease in children
Insights
Diagnosing pediatric Crohn
Area of Science:
- Pediatric Gastroenterology
- Diagnostic Imaging
Background:
- Diagnosis of Crohn's disease in children can be challenging due to non-specific symptoms and delayed investigations.
- Early identification is crucial for effective management and preventing long-term complications in pediatric patients.
Purpose of the Study:
- To review clinical and radiological features of Crohn's disease in children.
- To identify key indicators for early diagnosis and evaluate diagnostic imaging modalities.
Main Methods:
- Retrospective review of clinical and radiological data from 35 children diagnosed with Crohn's disease.
- Analysis of common disease sites, presenting symptoms, and diagnostic test effectiveness.
Main Results:
- Distal ileum and proximal colon were the most frequent sites of disease.
- Proximal small bowel disease presented with edema, clubbing, anemia, and growth stunting.
- Small bowel enema demonstrated higher efficacy than barium meal for disease detection.
Conclusions:
- Specific clinical features strongly suggest pediatric Crohn's disease, warranting small bowel enema.
- Small bowel enema is a valuable tool, despite being invasive.
- Colonoscopy is superior to colonic radiology for assessing colonic involvement.
Abstract:
Diagnosis of Crohn's disease in children may be delayed because of obscure presentation and inappropriate investigation. The clinical and radiological features in 35 children with Crohn's disease were reviewed retrospectively. The distal ileum and proximal colon were the most common sites of disease. Intestinal symptoms and signs were often overshadowed by nonspecific complaints. Proximal small bowel disease was characterised by oedema, clubbing, anaemia, and stunting of growth. The delay in diagnosis was less than in other series, although most prolonged in the group with proximal disease. We have identified a group of clinical features that strongly suggests Crohn's disease. In these patients, we believe a small bowel enema is justified. Small bowel enema, although invasive, is more effective than barium meal and follow-through for demonstrating Crohn's disease. Severity of radiological changes did not correlate with clinical assessment. Neither bowel stricture nor fistula was found. Radiology of the colon was insensitive and colonoscopy is better for assessing colonic disease.
