Endoscopic full-thickness gastric resection. (A) An elevated lesion is noted at the lesser curvature of upper body; (B) the lesion becomes distinct by chromoendoscopy using acetic acid and indigo carmine; (C) for sentinel node navigation, indocyanine green is injected into the submucosal layer after marking around the tumor; (D) endoscopic full-thickness resection is performed after sentinel node harvest and regional lymph node dissection; (E) final resection is performed with laparoscopy; (F) gastric closure is achieved with laparoscopy; (G) resected specimen; (H) resected lymph node.
