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.
- All participants with the need of PEG due to head neck cancers or esophageal carcinoma
- Minors, pregnant women, contraindication for endoscopy, contraindications for establishment of a PEG
1. Detection rate of a second cancer or precancerous lesions (Time Frame - The time frame is during the PEG insertion (approximately 15min)):
The detection rates for malignant or premalignant lesions in participants with head neck tumors will be compared when using BLI and white light endoscopy
- Active Comparator: Standard White Light Imaging
In this group the participants will be examined by white light endoscopy first and secondly with blue laser imaging technique during the same gastroscopy.
- Experimental: Blue Light Imaging
In this group the participants will be examined by blue laser imaging technique first and secondly with standard white light during the same gastroscopy.
- blue laser imaging:
The intervention is the push on demand activation of blue laser imaging technique during gastroscopy.
