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 indigocarmin; 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.
