Patient information: M, 60
Medical history: Preventive colonoscopy
1. LST-NG in WLI
LST-NG spreading across a fold
2. LST-NG with TXI
In TXI, the margins of the lesions become more evident. Stool is not interfering with TXI imaging.
3. LST-NG in NBI
NBI allows for analysis of superficial vessel pattern but is highly affected by remaining stool. NBI requires excellent bowel preparation and thorough flushing.
4. TXI after injection
After injection, TXI is delivering a better visibility of the demarcation line.
5. TXI during endoscopic resection
TXI is enhancing visibility of submucosal fibers and blood vessels in the submucosal space.
6. Bleeding spot with RDI
RDI is helping to identify bleeding spots and allows for precise coagulation.
