• History of colorectal cancer, inflammatory bowel disease, polyposis syndrome, hereditary nonpolyposis colorectal cancer (Lynch) syndrome, sclerosing encapsulating peritonitis, active diverticulitis in last 6 months or toxic megacolon
• Lower gastrointestinal bleeding within 28 days prior to the colonoscopy day
• Known bleeding tendency such as hemophilia or coagulation factor deficiencies
• Patient receiving antiplatelet or anticoagulation therapy apart from low-dose aspirin
• Known colonic stricture
• Known risk factors for abdominal adhesions such as history of complex abdominal or pelvis surgical procedures, based on investigator assessment
• Known abdominal wall hernias
• History of radiotherapy to the abdomen or pelvis
• History of mesenteric ischemia
• Known coronary ischemia or cardiovascular stroke within 3 months prior to the colonoscopy procedure
