Endoscopic Assessment of Colorectal Polyps

Area of Science:

• Gastroenterology
• Oncology
• Endoscopy

Background:

• Colorectal cancer is a leading cause of cancer death globally, with 150,000 US cases annually.
• Colonoscopy is the gold standard for detecting and managing precancerous colorectal lesions.
• Accurate characterization of lesions is crucial for effective treatment and organ preservation.

Purpose of the Study:

• To review current guidelines and techniques for diagnosing colorectal lesions during colonoscopy.
• To highlight the utility of advanced imaging modalities and classification systems.

Main Methods:

• Review of established endoscopic classification systems (Paris, NICE, JNET, Kudo, Hiroshima, Shudo).
• Discussion of techniques including chromoendoscopy, narrow-band imaging (NBI), and endocytoscopy.
• Evaluation of pit pattern and surface morphology for lesion assessment.

Main Results:

• Multiple classification systems exist to aid endoscopists in lesion diagnosis.
• Advanced imaging techniques improve the ability to predict lesion cytology.
• These tools facilitate informed decisions regarding resection and organ preservation.

Conclusions:

• Utilizing standardized classification systems and advanced imaging enhances diagnostic accuracy in colonoscopy.
• Predicting lesion cytology pre-resection optimizes treatment strategies.
• Maximizing organ preservation is achievable through precise endoscopic evaluation.
