Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The feasibility of confocal endomicroscopy; represented by: A. The sensitivity and specificity of optical biopsies (using final histopathology as gold standard). The sensitivity and specificity will be calculated for both the real time endoscopy diagnosis and the blinded assessment afterwards; B. In addition, the percentage of confocal images with insufficient image quality for histopathological diagnosis will be calculated on a per lesion basis. | — |
Secondary
| Measure | Time frame |
|---|---|
| The accuracies of CE, NBI, AFI and confocal endomicroscopy for the endoscopic differentiation of detected lesions will be compared with final histopathology as gold standard. | — |
