    Ischemic colitis diagnosis is challenging due to subjective visual assessments during colonoscopy, leading to misclassification of mucosal conditions.

  • 2

    A novel deep learning approach quantifies micro-capillary refill dynamics from colonoscopy video, providing objective perfusion measures.

  • 3

    The proposed method analyzes frame-by-frame color recovery after mucosal blanching to classify tissue viability in real time.

  • 4

    This technology aims to reduce interobserver variability and improve decision-making in treating ischemic colitis.

  • 5

    Pilot studies are needed to validate the deep learning approach and establish its role in guiding therapy for ischemic colitis.
