This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a special fluorescent dye called indocyanine green can help surgeons during esophageal or gastric cancer surgery. The dye makes lymph nodes and blood vessels glow during surgery, which may help your surgeon remove all the cancer-containing lymph nodes and check that the tissue reconnection (anastomosis) is healthy. Researchers believe this real-time guidance could improve how many lymph nodes are removed and ultimately improve survival rates.
Removing the right number and location of lymph nodes during cancer surgery is crucial for survival, but the number removed varies widely depending on the surgeon's experience. This treatment could provide surgeons with real-time visual guidance to make better decisions during surgery, reducing this variation and improving outcomes for all patients.

If you join this study, you would undergo your scheduled esophageal or gastric cancer surgery as planned. During the operation, your surgeon will use the fluorescent dye to help identify and remove lymph nodes more completely and to check that the tissue is properly connected with good blood flow. The study involves 60 patients total, and you would be monitored as part of the research to see how well this fluorescence guidance works.
