Barrett's esophagus (BE) is associated with a 30- to 50-fold increased risk for development of esophageal adenocarcinoma.1,2 For Barrett's high-grade dysplasia (HGD) and mucosal cancer, endoscopic ablation such as EMR is emerging as a viable option for potential cure.2,3 In EMR, the “suck and cut” technique uses either a transparent cap (“lift and cut” method) or a band ligator hood (“ligate and cut”) method.4,5 The “suck and cut” method is the most commonly practiced method for esophageal EMR. The band ligation technique often uses the multiband ligator to place bands on flat mucosa creating a “pseudopolyp” followed by resection with an electrocautery snare.
