Design outcomes
Primary
| Measure | Time frame |
|---|---|
| As this is a feasibility study, the main parameter is the (percentage of) cases in which SFR spectroscopy was possible to measure the reflectance during ERCP procedure. | — |
Secondary
| Measure | Time frame |
|---|---|
| The shape of the spectra and the optical absorption coefficients over a broad wavelength range will be used to distinguish benign and malign biliary strictures. To extract and quantify physiological information from the obtained spectra validated mathematical model, based on the knowledge of the absorption spectra of the chromophores, will be used. The extracted parameters are: 1) Microvascular saturation 2) Blood volume 3) Average vascular diameter 4) Parameter related to the scattering properties of tissue in real-time. The parameters will be linked to final histological analysis. | — |
