Head-Neck cancers are a significant burden all around the world. Patients suffering from one tumor are at high risk for a second cancer or another precancerous lesion. Before or during cancer treatment a PEG is needed to maintain a sufficient calories intake. PEG is established by performing a standard gastroscopy.~This randomised study wants to compare the detection rates of standard white light endoscopy compared to the additional use of blue laser imaging for second cancers or precancerous lesions in participants presenting for PEG establishment.
This study wants to focus on Carcinoma detection rates with blue laser imaging (BLI) for participants with head-neck cancer who need a percutaneous endoscopic gastrostomy (PEG). BLI is a new imaging technique that can easily be used within a standard gastroscopy.
