thyroid, parathyroid
lymphoma in cervical, mediastinal ln
aorta body tumour
periesophageal/mediastinal ln
thyroid, parathyroid
tumours
adenoma

carcinoma
consequence of stenosis mild
compensatory hypertrophy of muscles
consequence of stenosis severe
congesiton

perforation
putrid mediastinitis
pleuritis
periesophageaal phlegmone
causes of oesophageal dilation
ectasia
dilation
diverticulum
traction
pulsation
what is ectasia
before stenosis
due to innervation issue
what is dilation
whole length (megaoesophagus)
diverticulum
traction
or
pulsation
traction
true diverticulum
occur as a result of contracture from chronic inflammation
involves periosophageal, mediastinal structures
pulsation
false diverticulum
no muscle coat
congenital lesions of continuity
esophago-bronchial/ broncho- esophageal fistule
esophago-tracheal/tracheo esophageal fistule
