Gastroenterology and Artificial Intelligence: 4th Annual Global Artificial Intelligence Summit | August 2022-CADx Allows for Resect and Discard or Diagnose and Leave Behind

Video Summary

In this video, Dr. Cadman Leggett, a clinical gastroenterologist and assistant professor of medicine at the Mayo Clinic, discusses the role of computer-aided diagnosis (CADx) in detecting and diagnosing colorectal polyps. He explains that diminutive polyps, which are common during colonoscopy, rarely have cancer but still require polypectomy and histologic assessment to establish surveillance intervals. This can lead to significant costs and delays. Dr. Leggett discusses the ASGE-PV guidelines for polyp characterization and the barriers to implementing them, such as medical legal concerns and lack of financial incentives. He explains that CADx provides real-time assessment and classification of polyps as hyperplastic or adenomatous, potentially reducing the need for unnecessary polypectomies and pathology assessments. He also discusses studies on CADx systems and their performance in experts and non-experts, as well as potential pitfalls and future directions for CADx. Overall, CADx shows promise in standardizing practice, reducing costs, and improving diagnostic capabilities, but further research and consideration are needed for widespread implementation.
