Description of intervention(s) / exposure
Treatment: Surgery - Endoscopic Submucosal Dissection
Treatment: Surgery - Endoscopic Mucosal Resection

Active comparator: ESD - Lesion with overt stigmata of SMIC or those with high risk (=\> 10%) for covert SMIC.

Active comparator: EMR - Lesion with no overt or a low risk for (\<10%) for covert SMIC


Treatment: Surgery: Endoscopic Submucosal Dissection
Endoscopic Submucosal Dissection (ESD) results in en-bloc resection of LSL, regardless of lesion size. This allows for accurate histopathological assessment of SMIC, R0/R1 resection and depth of invasion. ESD is considered a potentially curative for superficial cancers (T1a).

Treatment: Surgery: Endoscopic Mucosal Resection
EMR is the current standard for treating colonic LSL and has been validated to be safe and efficacious. LSLs =\> 20mm are frequently resected piecemeal. Recent research show that resection margin soft coagulation reduces recurrence rates to those similar to en-bloc resections.
