Figure 3. Nonexposed endoscopic wall-inversion surgery (NEWS) with laparoscopic sentinel node (SN) mapping and sentinel lymphatic basin dissection for early-stage gastric cancer. (A) Indocyanine green (ICG) was endoscopically injected into the submucosal layer around the primary lesion; (B) ICG florescence imaging results in clear visualization of SNs and lymphatics; (C) laparoscopic circumferential seromuscular incision surrounding the primary tumor; (D and E) laparoscopic seromuscular suturing and inversion of the primary tumor site to the inside of the stomach; (F) endoscopic circumferential mucosal and submucosal incision for primary tumor resection; (G) endoscopically retrieved primary tumor
