Key Takeaway
Note that machine learning may assist in Hirschsprung diagnosis but should not replace expert histopathology interpretation.

This meta-analysis evaluated the diagnostic performance of machine learning (ML) models in identifying Hirschsprung disease. The analysis pooled data from several studies, specifically looking at ML applications in both barium enema imaging and rectal biopsy histopathology.

Results indicated that ML models demonstrated high sensitivity and specificity for barium enema-based diagnosis. In the context of rectal biopsies, machine learning was associated with reduced interpretation time, suggesting a potential role in improving workflow efficiency. However, the evidence regarding improved diagnostic performance specifically for biopsy results remains limited and heterogeneous.

The authors noted significant heterogeneity in study designs, data modalities, and reported outcomes as primary limitations. Furthermore, while ML shows promise as an assistive tool to enhance clinical efficiency, it is not intended to replace expert interpretation in histopathology.

Clinically, machine learning may serve as a valuable supportive tool for diagnosing Hirschsprung disease. However, routine implementation requires further prospective multicenter studies to establish definitive standards before these tools can be integrated into standard clinical practice.

Diagnosing Hirschsprung disease, a condition that affects how waste moves through the bowel, requires precision. New research looked at how machine learning—a type of artificial intelligence—can assist doctors in identifying this condition using different imaging and tissue tests.

When looking at barium enema studies (an X-ray test), machine learning showed high accuracy for both finding the disease and correctly identifying those without it. In cases involving rectal biopsies, where doctors look at tissue samples under a microscope, machine learning appeared to speed up the time it takes to interpret results.

While these results are encouraging, the evidence is still early. The study included data from different sources that varied greatly in design and method. Because of this variety, experts say machine learning should currently be seen as a tool to help doctors work more efficiently rather than a replacement for expert human judgment.

What this means for you:
Machine learning can improve the speed and accuracy of diagnosing Hirschsprung disease during specific tests.

Common questions

How accurate is machine learning for diagnosing this condition?

In studies using barium enemas, machine learning showed a sensitivity of 0.857 and a specificity of 0.880. These numbers suggest it can be quite effective at identifying the disease while also correctly ruling it out in patients who do not have it.

Can machine learning make the diagnosis process faster?

Yes, for rectal biopsy studies, machine learning was shown to reduce interpretation time. This means it could help doctors analyze tissue samples more quickly than current methods alone.

Will machines replace doctors in diagnosing Hirschsprung disease?

No. The evidence suggests that while machine learning is a helpful tool for efficiency, it should not replace the expert interpretation of a doctor when looking at tissue samples.

PURPOSE: To evaluate current evidence on machine learning (ML) for the diagnosis of Hirschsprung disease (HSCR) and summarize its diagnostic performance and potential clinical utility. METHODS: PubMed, Web of Science, Cochrane Library, and Scopus were systematically searched (January 2016-November 2025) for studies applying ML to HSCR diagnosis. Study quality was assessed using QUADAS-2. Findings were narratively synthesized, with exploratory meta-analysis performed where feasible. RESULTS: Eleven studies were included, with substantial heterogeneity in design, data modalities, and outcomes. Three barium enema-based studies were eligible for meta-analysis, showing pooled sensitivity of 0.857 (95% CI 0.738-0.936), specificity of 0.880 (95% CI 0.790-0.941), and an area under the curve of 0.927. In rectal biopsy-based studies, ML-assisted approaches appeared to reduce interpretation time, while evidence for improved diagnostic performance remains limited and heterogeneous. CONCLUSION: ML may have potential value in supporting HSCR diagnosis, particularly when combined with imaging and clinical data. In histopathology, ML appears more likely to serve as an assistive tool to improve efficiency and potentially enhance diagnostic performance rather than replace expert interpretation. Further prospective multicenter studies are needed before routine clinical implementation.
