Brief Summary

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.

Study Arms (2)

ESD

ACTIVE COMPARATOR

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

Procedure: Endoscopic Submucosal Dissection

EMR

ACTIVE COMPARATOR

Lesion with no overt or a low risk for (\<10%) for covert SMIC

Procedure: Endoscopic Mucosal Resection

Interventions

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).

ESD

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.
