Summary

This study tests whether a special dye, called indocyanine green, can help surgeons find cancer that has spread to nearby lymph nodes during esophageal cancer surgery. About 144 adults with esophageal cancer will take part. If the dye works well, it may allow doctors to remove fewer lymph nodes, reducing side effects like fluid leaks and immune problems.
