2.appear as a plaque-like lesion along one wall of the oesophagus which is frequently ulcerated, or an area of granular, flat mucosa with irregular wall.

carcinoma of oesophagus
Clinical manifestations
1.carcinoma of esophagus is a malignant tumor arising from the oesophagus , most in over 40 years old.
is swallowed slowly
esophageal varices
Late stage (serious)
involving the whole esophagus mucosae is displaced of filling defects which sizes are
different wriggling is weak, barium is swallowed slowly
Oesophageal varices
CT at mid-chest level
demonstrates multiple tubular and rounded contrast enhanced structures surrounding the oesophagus and representing perioesophageal varices (large arrows). Enhancement of the thickened oesophageal wall (small arrow) is due to enlarged submucosal
esophageal varices
early stage ：
mucosae of distal esophagus are thickening, circuitous
the wall is like saw-tooth contraction and relaxation is normal, barium is swallowed
3.swallow difficultly step by step
carcinoma of oesophagus
Early oesophageal carcinoma
1.limited to the mucosa or submucosa without lymphatic involvement. Their prognosis is much better than that of more developed carcinomas.
esophageal varices
appearances of x-ray
Thickening, circuitous and disturbance of mucosa longitudinal serpiginous filling defects
Dividing line of normal and abnormal esophagus iices result from dilatation of
submucosal veins in the esophagus acting as collateral venous drainage in the presence of obstruction elsewhere.
Usually this is caused by cirrhosis of the liver so that portal blood flow is rerouted via the esophagus to the superior vena cava.

x-ray
barium swallow: revealing the mucosae of middle and lower oesophagus
erect: used for middle and late stage of oesophageal varices
supine/prone：beneficial for early stage of oesophageal varices
2.the squamous cell type predominates in the upper and middle third of the oesophagus; adenocarcinoma represents over 60% of all carcinormas of the lower third.

esophageal varices
middle stage（typical）：
mucosae of middle and distal esophagus are thickening , circuitous
filling defect is like earthworm contraction and relaxation is not enough good, barium
