This study aims to explore the value of indocyanine green (ICG) in laparoscopic distal gastrectomy with lymph node dissection for early gastric cancer.The patients with early gastric adenocarcinoma (cT1, N-/+, M0) will be studied.
After being informed about the study and potential risks, all patients giving written informed consent will receiving injection of indocyanine greenat 8 points around the primary tumor with gastroscope 1 day before surgery. During the operation, laparoscopic gastrectomy and perigastric lymph node dissection were performed under ICG imaging equipment. After the surgical specimens were isolated, under the fluorescent illumination of the ICG imaging equipment, the lymph nodes that showed fluorescence and the lymph nodes that did not show fluorescence were collected from each LN station.
