ESTD
During the ESTD procedure,after marking and submucosal injection, incisions were made at both the anal and oral sides of the lesion, and the submucosa under the lesion was then dissected to create a tunnel between the distal and proximal incisions. When the endscope reached the lower incision, the distal end of the esophageal lumen could be visualized , then two lateral mucosal incisions were made, thus completing the ESD procedure.
