Presentation and endoscopic resection technique of neonatal esophageal choristoma: A case report

Figure 4 Illustration of the procedure. A: A slim endoscope was advanced down the esophagus along the longitudinal axis of the mass, which was oriented caudally. A slim-scope compatible snare was used to flip the mass cephalad; B: A hemoclip was applied under direct vision to the tip of the mass. The hemoclip secured a suture wire, allowing upward traction to be exerted on the mass; C: An injection needle sized for the slim scope was used to inject the base of the lesion with an adrenaline-saline solution (1 mg adrenaline in 10 mL normal saline, total volume 2 mL) to create a submucosal lift; D: A slim-scope compatible snare was then inserted through the endoscope and advanced over the traction wire, the clip, and the mass body until it reached the lesion’s base; E: Resection of the mass was performed using a hot-polypectomy technique (ERBE VIO 300 Endocut Q, effect 2, cut duration 1, cut interval 6, maximum output 770).
