Raman spectroscopy is an optical method based on the analysis of scattered monochromatic light. Raman spectroscopy is able to provide a molecular 'fingerprint' of the tissue to determine its type. The aim of this pilot study was to develop a methodology for in vivo Raman spectroscopy in bile ducts to improve the current diagnostic capabilities of extrahepatic cholangiocarcinoma.",[26,27,28,29,30,31,32,33,34],"Cholangiocarcinoma, Extrahepatic","Cholangiocarcinoma of the Extrahepatic Bile Duct","Cholangiocarcinoma, Perihilar","Diagnosis","Raman Spectroscopy","Klatskin Tumor","Endoscopy","Biliary Stricture","Malignant Biliary Stricture","RECRUITING","2025-06-29",{"date":38,"type":39},"2025-07-02","ACTUAL",{"date":41,"type":39},"2023-02-04",{"date":43,"type":20},"2025-07-30",{"name":45,"class":46},"University Hospital Olomouc","OTHER"]
