Area of Science:

  • Gastroenterology and Oncology
  • Medical Technology and Artificial Intelligence

Background:

  • The resect-and-discard strategy for colorectal cancer prevention relies on real-time optical diagnosis of diminutive polyps during colonoscopy, aiming to avoid histopathological analysis.
  • Despite evidence supporting its diagnostic accuracy and endorsement by major gastroenterology societies, widespread implementation is hindered by clinician confidence, medico-legal concerns, and procedural challenges.

Purpose of the Study:

  • To review current evidence on the resect-and-discard strategy for colorectal cancer prevention.
  • To identify key barriers to its implementation and propose future research directions.
  • To explore the potential role of artificial intelligence in overcoming these barriers.

Main Methods:

  • Literature review of studies on the resect-and-discard strategy, optical diagnosis, and artificial intelligence in colonoscopy.
  • Analysis of implementation barriers, including clinician factors, legal issues, and procedural aspects.
  • Evaluation of emerging AI technologies for polyp diagnosis and size estimation.

Main Results:

  • The resect-and-discard strategy shows promise, with early real-world data indicating patient approval and potential cost/environmental benefits.
  • Artificial intelligence systems show potential to improve diagnostic accuracy and clinician acceptance, addressing key implementation barriers.
  • Significant unanswered questions remain regarding optimal polyp size estimation techniques and AI's ability to differentiate histological features.

Conclusions:

  • Widespread adoption of the resect-and-discard strategy requires addressing clinician confidence, medico-legal uncertainties, and procedural standardization.
  • Artificial intelligence offers a promising avenue to enhance the accuracy and feasibility of this strategy.
  • Further research is crucial to refine AI applications, establish quality assurance, and clarify medico-legal frameworks for successful implementation.
