Abstract

In recent years, there has been an increasing interest in the use of optical spectroscopic technologies for early cancer detection in the gastrointestinal system. Raman endoscopy is a unique fiber-optic spectroscopic technology for in vivo histopathological assessment of tissue based on endogenous biomolecules. Recent technical advances have enabled in vivo tissue Raman measurements in real-time during clinical endoscopic examination. The endoscopist can apply Raman endoscope to analyze the biomolecular signature of cells and tissues in vivo, thereby enabling noninvasive optical biopsies of suspicious lesions during ongoing endoscopy. In this article, we review the applications of Raman endoscopy in the gastrointestinal system and also discuss its potential function and role in gastrointestinal endoscopy and therapeutics. The results of the latest Raman clinical trials are summarized, illustrating the great potential of Raman endoscope technology for non-invasive, in vivo diagnosis and detection of pre-cancer and early cancer in the gastrointestinal system.
