I don't see how a barium swallow study would give them any information about node involvement. What it will show are structure related abnormalities, but what they are exactly... the test won't tell. It may for instance show that there is narrow area, but why that is narrow, (a tumor, tramatic inflamation etc.) it can not determine.
