Core Tip

Core Tip: Colorectal endoscopic submucosal dissection (ESD) is an established organ-preserving treatment for selected superficial colorectal neoplasms, particularly early colorectal cancer with suspected superficial submucosal invasion. International guidelines recognize ESD as the preferred technique when en bloc resection is required for accurate histopathological evaluation and curative treatment. Compared with endoscopic mucosal resection, ESD achieves higher en bloc and complete resection rates, improving assessment of invasion depth and resection margins. In appropriately selected lesions, colorectal ESD provides favorable long-term oncologic outcomes comparable to surgery while preserving the native organ through a minimally invasive approach.
