A guide to multimodal endoscopy imaging for gastrointestinal malignancy - an early indicator

Area of Science:

• Gastroenterology
• Medical Imaging
• Endoscopy

Background:

• Multimodality imaging is crucial for endoscopic surveillance in detecting neoplastic lesions like dysplasia and intramucosal cancer.
• Standard endoscopy often fails to detect subtle mucosal abnormalities.

Purpose of the Study:

• To review advanced imaging techniques for gastrointestinal tract diagnostic investigation.
• To highlight the role of multimodal endoscopic imaging in early disease detection, especially pre-malignant lesions.

Main Methods:

• The review covers virtual chromoendoscopy, narrow-band imaging, autofluorescence imaging, optical coherence tomography, confocal endomicroscopy, and volumetric laser endomicroscopy.
• These techniques are categorized into primary detection and targeted imaging/characterization.

Main Results:

• Multimodality imaging significantly improves the efficacy of endoscopic surveillance and therapeutic procedures.
• These advanced methods reveal mucosal abnormalities missed by conventional endoscopy, aiding detailed visualization and histological evaluation.

Conclusions:

• The reviewed imaging techniques offer valuable insights for the diagnostic investigation of the gastrointestinal tract.
• Multimodal endoscopic imaging is essential for the early detection of pre-malignant and malignant lesions in the esophagus, stomach, and colon.
