SENORITA 1 trial showed laparoscopic sentinel lymph node biopsy and stomach preserving surgery in early gastric cancer can increase the quality of life. (Ryu KW et al. JCO 2022) The radioactive isotope is difficult to use because of the hazard of radiation and shortage of materials. The aim of this study is to investigate whether laparoscopic sentinel lymph node biopsy and stomach-preserving surgery using only fluorescence is feasible.
