Spots Global Cancer Trial Database for Cold Snare Endoscopic Mucosal Resection (EMR) vs Cold EMR With Margin Snare Tip Soft Coagulation (STSC)

Study Description

Brief Summary: Randomised controlled trial comparing cold snare endoscopic mucosal resection (EMR) with cold snare EMR and adjuvant margin STSC in the complete resection of 15-40mm lateral-spreading adenomas

Detailed Description: Rationale: Conventional EMR is well-established for the resection of lateral-spreading adenomas and has been shown to be highly efficacious with adjuvant STSC. Cauterisation-related complications occur relatively frequently and while endoscopically treatable, still carry morbidity not seen in current cold snare polypectomy data. Cold snare polypectomy has an excellent safety profile for smaller polyps, without cauterisation-related adverse events. Limited data on cold EMR for large adenomatous laterally-spreading lesions shows minimal complications. Efficacy, however, is yet to be evaluated in prospective randomised trials. Observational data demonstrates recurrence rates exceeding conventional EMR. Since STSC causes significant reduction in recurrence in conventional EMR, the safety and efficacy of this adjuvant technique, when compared to isolated cold snare EMR, has theoretical advantages in both safety and efficacy. The safety and efficacy of these two techniques will therefore be compared in a randomised controlled trial. Hypothesis: Cold snare EMR of 15-40mm lateral-spreading adenomas with adjuvant STSC is expected to be superior regarding complete resection and adenoma recurrence rates as compared to cold snare EMR.
