Morphological classifications of gastrointestinal lesions

Area of Science:

• Gastroenterology
• Endoscopic Imaging
• Oncology

Background:

• Gastrointestinal endoscopy screening is increasing globally.
• Complex lesions require precise characterization for optimal treatment.
• Assessing submucosal invasion is critical for determining endoscopic resectability.

Purpose of the Study:

• To present a systematic endoscopic approach for lesion assessment.
• To stratify risk for submucosal invasion.
• To highlight the role of advanced imaging in lesion characterization.

Main Methods:

• Systematic endoscopic assessment of lesion location and size.
• Application of the Paris classification system.
• Utilizing lateral spreading tumor classification and advanced endoscopic imaging for surface pattern evaluation.

Main Results:

• A structured approach enhances lesion characterization.
• Advanced imaging improves the assessment of mucosal surface patterns.
• Accurate characterization aids in determining suitability for endoscopic resection.

Conclusions:

• A systematic endoscopic assessment is crucial for managing gastrointestinal lesions.
• Advanced imaging techniques are valuable tools for risk stratification.
• This approach optimizes treatment decisions, particularly for endoscopic removal.
