Figure 4 Intraoperative endoscopic view of laparoscopic and endoscopic cooperative surgery. A: First, the location of the tumor is confirmed; B: The periphery of the tumor is marked using argon plasma coagulation as close as possible to the tumor edge; C: Glycerin mixed with indigo blue is injected into the submucosal layer; D: The whole circumference of the marked area is cut using an insulation-tipped diathermic knife; E: An intentional perforation is made; F: The laparoscopic light is too dazzling for the endoscopic side; G: Intraluminal view after suturing. The absence of stenosis and malformation is confirmed; H: Esophageal mucosa injury by the plastic bag during specimen removal.
