5. what's clinically relevant about the lymphatics of the oesophagus
they're bidirectional: drains to deep cervical and juxtaoesophageal nodes - important for spread of cancer
very complex, so hard to find root of cancer
stomach cancer metastasises through the juxtaoesphageal nodes
throat cancer metastasises down to juxtaoesphageal nodes
