Diagnosis can be confirmed in any patient with perisistent
dysphagia by a barium study or oesophagoscopy.Biopsy will als
provide diagnosis regards the type of carcinoma (squamous or
adenocarcinoma).
EVALUATION
Since 1980 endoscopy ultra sound has made it possible to define
invasion of muscle of oesophagus and establish lymph node
involvement. This mode of examination is however limited to
those where the ultra sound probe canpass through the lumen
beyond the tumour. However, barium study should be the first
mode of examination. Chest Xray mayalso give information such
as:
* air fluid level in oesophagus
* abnormal mediastinal soft tissue mass
* mass pulmonary effusion or lung secondaries
CT scanning permits retrieval of information regarding
oesophageal wall thickening and tumour spread into the
mediestinum and lymph nodes, pulmonary liver or adrenal
metastasis can also be identified.
Bronchoscopy should be done in all cases to eliminate the
possibility of extension to the respiratorypassages.
