Brief Summary

Diagnosis of extrahepatic cholangiocarcinoma is challenging because the yield of imaging and tissue sampling is limited. 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.

Outcome Measures

Primary Outcomes (1)

  • The differences in Raman spectra of malignant biliary tissue compared to healthy biliary tissue

    During single ERCP procedure, we take 20 measurements of the Raman spectra (10 from malignant biliary tissue and 10 from healthy biliary tissue) that each tissue emits after interaction with the laser light. We are interested in the specific difference in the spectra of each tissue, which will be shown as a two-dimensional curve. The differences in the spectra of each tissue will be reflected by a change in the shape of the curve.

    Perioperative/Periprocedural

Study Arms (1)

patients with extrahepatic cholangiocarcinoma

EXPERIMENTAL

20 patients with known cholangiocarcinoma indicated for endoscopic retrograde cholangiopancreatography over 18 years of age

Procedure: Endoscopic retrograde cholangiopancreatography (ERCP)

Interventions

Insertion of a endoscopic fiber-optic Raman probe under fluoroscopic control during endoscopic retrograde cholangiopancreatography to measure Raman spectra of extrahepatic cholangiocarcinoma and healthy bile duct.
