Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - SCAR technique

Active comparator: SERT 0, SCAR (low risk) - Patients with Sydney EMR Recurrence Tool (SERT scoring) score 0. These patients will be invited to return for follow up at 18 months and will have thermal ablation (SCAR technique) of the endoscopic resection defect margin.

Active comparator: SERT 1-4, SCAR (high risk) - Patients with Sydney EMR Recurrence Tool score 1-4 (SERT scoring). These patients will be invited to return for follow up at 4-6 months and will have thermal ablation (SCAR technique) of the endoscopic resection defect margin.


Treatment: Surgery: SCAR technique
Thermal ablation of the EMR margin using ERBE Soft Coagulation (Effect 4, 80 watts) and the operator choice of endoscopic resection snare
