The primary specific aim is to perform a randomized controlled trial (RCT) to compare rates
of delayed hemorrhage after DEP detection of arterial blood flow and focal treatment in
PPIU's (treatment arm) with standard treatment using medical guidelines alone (controls) for
prevention of delayed bleeding in high risk patients (on anti-coagulants or anti-platelet
drugs or with large ulcers) after snare resection of benign colon polyps.
