ESD for Colorectal LSL Using a Selective Strategy - a Prospective Cohort Study
Colonic Laterally spreading lesions (LSL) =\> 20mm are at high risk to progress to cancer. Overt stigmata of submucosal invasive cancer (SMIC) has been well characterized and includes ulceration and surface pit pattern changes as per the Kudo classification of type V. In a recent report, risk factors for LSL with SMIC and no overt stigmata (i.e. covert SMIC) were described. Resection of these lesions 'en-bloc' can allow for better histological staging and potentially reduce the need for surgical resection.
