Abstract
Eosinophilic esophagitis (EoE) is a chronic esophageal disorder marked by
eosinophil-dominated inflammation. Diagnosing EoE usually involves endoscopic
inspection of the esophageal mucosa and obtaining esophageal biopsies for
histologic confirmation. Recent advances have seen AI-assisted endoscopic
imaging, guided by the EREFS system, emerge as a potential alternative to
reduce reliance on invasive histological assessments. Despite these
advancements, significant challenges persist due to the limited availability of
data for training AI models - a common issue even in the development of AI for
more prevalent diseases. This study seeks to improve the performance of deep
learning-based EoE phenotype classification by augmenting our training data
with a diverse set of images from online platforms, public datasets, and
electronic textbooks increasing our dataset from 435 to 7050 images. We
utilized the Data-efficient Image Transformer for image classification and
incorporated attention map visualizations to boost interpretability. The
findings show that our expanded dataset and model enhancements improved
diagnostic accuracy, robustness, and comprehensive analysis, enhancing patient
outcomes.
