Cellvizio Optical Biopsy enables “on the spot” characterization of intestinal metaplasia and early gastric cancer

Early-stage stomach cancer is very difficult to detect because it rarely causes symptoms. By the time the symptoms appear, the cancer has often reached an advanced stage, and in many cases, metastasized. This is one of the main reasons for its relatively poor prognosis.

Cellvizio Optical Biopsy is a through-the-scope procedure that fits any standard practice and equipment.

Cellvizio provides physicians microscopic images of tissue during standard endoscopies, in real-time, which allows better detection of intestinal metaplasia and early diagnosis of gastric cancer.1-5

"Real-time pCLE and targeted biopsies after Flexible spectral Imaging Colour Enhancement (FICE) improved the diagnostic yield for the detection of gastric intestinal metaplasia, gastric intraepithelial neoplasia, and early gastric cancer and only required about half the number of biopsies versus FICE with standard biopsies". This may allow for a better regimen for endoscopic surveillance and subsequent treatment of patients with premalignant and malignant gastric abnormalities"
