14. Fig. 13
Tumor infiltration and lymph node metastatic rate of T1 esophageal cancer. Early esophageal cancers are in situ lesions (carcinoma in situ) or T1 tumors. T1 tumors are subcategorized as T1a or T1b depending on the depth of invasion. T1a: M1 or SSM, intraepithelial cancer; M2 or LPM, cancer with invasion into the lamina propria mucosae; M3 or DMM, cancer reaching to the muscularis mucosae. T1b: SM1, cancer with invasion into one-third of the submucosa; SM2, cancer with invasion into the middle third of the submucosa; SM3, cancer with invasion into the lower third of the submucosa.

Fluorescent navigation after injection of indocyanine green dye into the submucosal layer beside the tumor. (A) Lymph flow (arrows) and a sentinel node in the right recurrent nerve (arrow head) are visualized with an infrared endoscopic camera system. (B) The sentinel node (arrow head) and right recurrent nerve (arrows) are retrieved. (C) The fluorescent camera clearly shows the sentinel node in the right recurrent nerve (arrow head) and the lymph flow (arrows).

Intraoperative findings in the upper mediastinum during thoracoscopic surgery. (A) A radioactive (hot) node along the right recurrent laryngeal nerve is identified using a hand-held gamma probe. (B) This sentinel node is harvested using a vessel-sealing device. (C) The harvested sentinel node is placed on the gamma probe. The intensity of radioactivity in the sentinel node is shown by the scintillation counter. (D) Dual-tracer method identifies a hot and blue-stained sentinel node along the left gastric artery.
