Evaluation of the string test in intestinal bacterial overgrowth

Summary
The pediatric string test accurately assesses small intestinal bacterial overgrowth in children with chronic diarrhea. This simple and safe method matches the diagnostic efficacy of duodenal aspiration for evaluating microflora.
Area of Science:
- Pediatric Gastroenterology
- Microbiology
- Diagnostic Efficacy
Background:
- Chronic diarrhea in children can be caused by bacterial overgrowth in the small intestine.
- Accurate diagnosis of small intestinal microflora is crucial for effective treatment.
Purpose of the Study:
- To compare the diagnostic accuracy of the string test (EnteroTest-Pediatric) with duodenal aspiration for assessing bacterial overgrowth in children.
- To evaluate the string test as a reliable diagnostic tool for small-intestinal microflora.
Main Methods:
- A comparative study involving 18 children diagnosed with chronic diarrhea.
- Both the string test (EnteroTest-Pediatric) and duodenal aspiration were performed on all participants.
- Isolation and significance of microorganisms in the small intestine were analyzed for both methods.
Main Results:
- The isolation and significance of organisms identified in the small intestine were identical between the string test and duodenal aspiration in all 18 children.
- Both diagnostic methods demonstrated comparable efficacy in assessing small-intestinal microflora.
Conclusions:
- The string test (EnteroTest-Pediatric) is a highly accurate method for assessing bacterial overgrowth and microflora in the small intestine of children.
- The string test offers a simple, safe, and effective alternative to duodenal aspiration for diagnosing small-intestinal bacterial overgrowth in pediatric patients.
