Incomplete resection after macroscopic radical endoscopic resection of T1 colorectal cancer—should a paradigm-changing approach to address the risk be considered?
Compared with laparoscopic resection, endoscopic resection was found to be cost-effective in the management of complex colon polyps. The effectiveness was due to superior technical success and reduced adverse event rates associated of endoscopic resection, and to the higher cost of laparoscopic resection (1). The economic analysis could explain why endoscopic interventions such as endoscopic mucosal resection and endoscopic submucosal dissection have gained popularity and are being increasingly incorporated into the management of T1 colorectal cancer (CRC). T1 CRC is one that has grown through the muscularis mucosa and extends into the submucosa (2).
