NCT01368731

Brief Summary

The hypothesis of this study is that prophylactic coagulation therapy with coagulation forceps to visible vessels within the mucosal defect for colonic Endoscopic Mucosal Resection (EMR) will reduce the rate of delayed bleeding when compared with current established standard EMR technique.

Outcome Measures

Primary Outcomes (1)

  • Presence of delayed bleeding

    14 days

Study Arms (2)

nil prophylactic coagulation

NO INTERVENTION

Prophylactic coagulation

ACTIVE COMPARATOR
Procedure: Prophylactic use of coagulation therapy

Interventions

The procedure is completed as per usual, and if the patient has been randomized to the intervention group the appropriate coagulation therapy will be applied immediately after standard EMR to visible vessels within the mucosal resection area.
