While colorectal cancer is a treatable disease with a relative 5-yr survival rate of 90% if detected in the early and localized stage, it remains the third leading cause of cancer deaths in the United States for both men and women [1]. Despite the recent efforts in wireless capsule endoscopy (WCE) to decrease the invasiveness of the requisite colon cancer screening procedure, the colonoscopy remains the gold standard for the diagnosis and treatment of this disease [2].

A colonoscopy procedure, which involves the insertion of a scope through the anus, rectum, and colon to locate and remove precancerous polyps, can be uncomfortable and even painful for patients, with the potential to result in tissue damage and in rare cases, perforation of the colon [3]. This procedure can also be physically tasking for physicians, and even experienced surgeons may struggle...
