Submucosal Tunnel Endoscopic Resection for Esophageal Submucosal Tumors: A Multicenter Study

Figure 1

Case illustration of submucosal tunnel endoscopic resection for esophageal submucosal tumor (SMT). (a) A SMT located at the midesophagus shown by white light. (b) A 2 cm longitudinal mucosal incision was made using a hybrid knife, approximately 5 cm proximal to the SMT, and a straight submucosal tunnel was made until the tumor was visible. (c) Resection was done along the margin of the SMT using the hybrid knife. (d) The wound of the submucosal tunnel was checked after the removal of the tumor. (e) Metal clips were used to close the entrance of the tunnel. (f) The resected specimen was measured, and the final pathological diagnosis confirmed a 35 mm leiomyoma.
