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


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.

  2. 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.


Secondary Outcome Measures :
  1. 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

  2. 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.
