Small-bowel involvement occurs in approximately 70% of Crohn disease cases, and lesions are confined to the small bowel in nearly 30%.
-
2
Small-bowel capsule endoscopy visualizes Crohn disease lesions throughout the small intestine, but its large image volume makes manual interpretation time-consuming and reader-dependent.
-
3
The Lewis score quantifies small-bowel inflammatory activity using villous edema, ulceration, and stenosis.
-
4
Eval-Model is a multitask deep learning framework developed to automate Lewis score estimation during capsule endoscopy examinations for small-bowel Crohn disease.

5
Eval-Model combines lesion detection and localization, edema and ulcer segmentation, stenosis classification, and LSTM-based temporal regression to predict an examination-level Lewis score.
