Abstract

Endoscopic resection for large colorectal lesion is effective and cost-saving than surgery. Piecemeal resections are often effective if applied meticulously but endoscopic submucosal dissection (ESD) allows meritorious removal of large lesions in one piece. For rectal lesions, transanal endoscopic microsurgery or transanal minimally invasive surgery offers more radical transmural resection but ESD is also effective for removal of complex rectal lesions. Surgical resection with lymph node dissection is the gold standard for invasive cancer; however, the management of low-risk early-stage colorectal cancer is worth debating. Treatment selection for large colorectal lesions is discussed based on lesion factor and treatment outcomes.
