Abstract
Introduction
Growth arising from the inner lining of the gastrointestinal tract such as colonic lipomas and colorectal polyps can be neoplastic or non-neoplastic with the potential to develop into adenomatous or cancerous lesions and subsequently grow into large tumours (Nallamothu & Adler, 2011). The goal of screening or surveillance of colorectal cancer is to detect colorectal neoplasia or precancerous lesions in their early stages, so that they can be removed endoscopically through colonoscopy (polypectomy) or treated in order to reduce the risk of colorectal cancer development (Gallegos-Orozco & Gurudu, 2010; Nallamothu & Adler, 2011; Fyock & Draganov, 2010). While early detection of solitary colorectal cancer lesions can be successfully resected before they develop into large tumours, continued surveillance following curative resection is important to prevent recurrence (Scheer & Auer, 2009).
