Colorectal cancer (CRC) at early stage often has no symptoms, which causes delay of successful treatments. Colonoscopy is clinically performed for screening, during which biopsy may be conducted; however, it is difficult to determine early stage CRC by ordinary endoscopy even with dye due to the insufficient superficial scope of colorectal surface for pre-cancerous diagnosis. Endoscopic ultrasound (EUS) has been widely used to visualize overall depth-view five-layered structural alteration of colorectal tract. The field of knowledge of high-frequency EUS with quantitative ultrasound (QUS) for early colorectal cancer diagnosis is yet to be fully determined and a reproducible and feasible animal model is appropriate for further development of this novel modality. VX2 CRC Rabbit model is first time used as a model for endoscopic ultrasound imaging according to our knowledge. In this study, we for the first time show the application of high-frequency EUS along with QUS to characterize malignant colorectal tumor and benign colorectal tissue in a rabbit model of VX2 colorectal cancer.
