About this trial

This is an interventional diagnostic trial for Colorectal Cancer focused on measuring Colonoscopy, Fluorescence guided surgery

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Participant is willing and able to give informed consent for participation in the study.
  • Male or female, aged 18 years or above
  • Participants undergoing endoscopic procedures including colonoscopy and flexible sigmoidoscopy or transanal endoscopic microsurgery (TEMS), including robotic assisted TEMS
  • In the investigator's opinion, is able and willing to comply with all study requirements

Exclusion Criteria

  • Participant who is unable to unwilling to give informed consent
  • Female participant who is pregnant, lactating or planning pregnancy during the course of the trial. If there is an uncertainty regarding whether a woman could be pregnant, then they will be excluded from the study
  • Participants with known egg allergies, ovalbumin allergy and soya allergies

Sites / Locations

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Fluorescent Lectin Application

Arm Description

Fluorescein conjugated wisteria floribunda will be sprayed onto the colonic surface during colonoscopy or TEM surgery.

Outcomes

Primary Outcome Measures

Signal to background ratios of identified colonic lesions under white light and under fluorescence
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
Number of lesions identified under white light colonoscopy will be compared to the number of lesions identified under fluorescence.

Secondary Outcome Measures

Number of dysplastic and cancerous lesions identified under white light and fluorescence in different subgroups
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.
Planned resection margins will be compared under white light and under fluorescence. R0/R1 resection rates will be assessed post operatively.
