Clinical Trials

Inclusion Criteria:

• Any patient ≥ 18 years of age who presents for a colonoscopy and who does not have criteria for exclusion.
• Patients with a ≥ 20mm non-pedunculated colorectal polyp.

Exclusion Criteria:

• Pedunculated polyps (as defined by Paris Classification type Ip).
• Suspected adenocarcinoma with deep submucosal invasion.
• Patients with ulcerated depressed lesions (as defined by Paris Classification type III) or confirmed adenocarcinoma.
• Patients with inflammatory bowel disease.
• Patients who are receiving an emergency colonoscopy.
• Poor general health (ASA class > 3).
• Patients with coagulopathy with an elevated INR ≥ 1.5, or platelets < 50.
• Inadequate bowel preparation (Boston Bowel Prep Scale, total score ≤ 2).
• Pregnancy.
• For patients who did not meet patient inclusion criteria, we will record the reason for ineligibility.
• For consented and study subjects who did not meet polyp inclusion criteria, we will collect information on reasons for exclusion of polyps (including size, morphology, location, histology), how they were removed (hot or cold snare resection) and whether bleeding occurred during the resection.
