Experimental: Fluorescent Lectin Application
Fluorescein conjugated wisteria floribunda will be sprayed onto the colonic surface during colonoscopy or TEM surgery.

Drug: Fluorescent Lectin Application
Fluorescein conjugated wisteria floribunda (a lectin).

- Signal to background ratios of identified colonic lesions under white light and under fluorescence [ Time Frame: During procedure ]This outcome measure compares the fluorescence signal of lesions identified during colonoscopy.
- Number of dysplastic and cancerous lesions identified under white light and under fluorescence [ Time Frame: During procedure ]Number of lesions identified under white light colonoscopy will be compared to the number of lesions identified under fluorescence.
- Number of dysplastic and cancerous lesions identified under white light and fluorescence in different subgroups [ Time Frame: 12 months ]Assessment of subgroups including ulcerative colitis, lesions suspicious of sessile serrated adenomas / traditional serrated adenomas
- Resection margin of of lesions undergoing TEMS resection under white light and under fluorescence. [ Time Frame: 12 months ]Planned resection margins will be compared under white light and under fluorescence. R0/R1 resection rates will be assessed post operatively.
