Gastrointestinal OCT

Gastrointestinal OCT

    Yongstar OCTIS is a real-time 3D tomography optical imaging technology. The physical principle of OCT is similar to ultrasound, using near-infrared light, through the combination of endoscopes, fine needles, catheters, laparoscopes and other devices, to provide micrometer-level resolution of the sectional image of living tissue morphology. Current studies suggest that OCT technology shows significant application potential and value in the following areas of gastrointestinal oncology surgery:

(1) Early tumor screening and diagnosis: It can distinguish the difference between polyp tissue, normal tissue, and malignant tissue, and may distinguish precancerous lesions, such as gastrointestinal metaplasia, Helicobacter pylori associated gastritis, early gastric cancer involving mucosa or submucosa, and distinguish adenomatous polyps from proliferative polyps.

(2) Optical biopsy of lymph nodes: visualize the microscopic features within the tissue, distinguish the lymph node tissue from the surrounding adipocytes, and show the structure of lymph nodes (such as germinal centers and intracodular blood vessels), and show the changes in the microscopic structure of lymph nodes during metastatic tumor invasion.

(3) Accurate surgical navigation: Through rapid large-area scanning, the surgical resection of neoplastic diseases is guided at the cellular level, residual tumor lesions at the tumor edge are scanned, and the appropriate scope of intestinal resection and lymph node dissection is determined.
