Lymphatic Drainage of Esophagus |
Rich network of lymphatic vessels, in
the lamina propria of the mucosa but
also in the other layers
Cervical esophagus:
lymph vessels → lower internal jugular
nodes and upper
tracheal nodes;
The internal jugular chain
( a subdivision
of the deep cervical
nodes
) lies along the internal jugular vein
drain on the left side
to thoracic
duct
and on the right side
to the short right lymph duct
openning into the
right subclavian vein
at the angle
formed by them
Thoracic esophagus:
upper
lymphatics drain posteriorly
to posterior parietal
nodes and diaphragmatic
nodes;
anteriorly,
to tracheal nodes(paratracheal
nodes)
and tracheo-bronchial nodes
form a chain on each side along the recurrent
nerve;
lower
lymphatics down to retrocardiac
and infracardiac nodes.
The posterior parietal nodes
comprise the posterior mediastinal
and the intercostal
nodes, both of them upward
drain into the thoracic duct
and the right lymph duct
Abdominal esophagus:
similar to the upper portion of the lesser curvature,
to paracardial node( cardiac node )
→ celiac nodes
→ through the esophageal
hiatus connected
with the nodes above the diaphragm empty into the
cisterna chyli
or the thoracic duct
