Esophageal cancer Diagnosis
Some tests used to diagnosis for Esophageal cancer include:
X-ray barium meal examination. Inspection of the esophageal peristalsis observed conditions, diastolic wall, the esophageal mucosal changes in esophageal filling defect and the degree of obstruction. Stop or reverse peristalsis of esophageal peristalsis, food and local rigidity of the wall can not fully expand, esophageal mucosal disorders, disruption and destruction, esophageal lumen stenosis, irregular filling defect, ulcer, or fistula formation and esophageal abnormalities, such as axial are important signs of esophageal cancer. Hypotonic double contrast of the detection of early esophageal cancer more effectively than conventional angiography.
Fiber gastroscopy esophagus. Cancer may be the form of direct observation, and under direct vision perform biopsy to determine the confirmed diagnosis.
Esophageal mucosa exfoliative cytology test. Application of dual-chamber airbag wire collector tube cell esophageal ingestion, through expansion of lesions after paragraph inflatable balloon, and then slowly pulled out the airbag. Access network sets of brush smears taken for cytological examination, the positive rate of up to 90%, often found in some early ill for esophageal cancer an important method for large-scale census.
Esophagus CT scan . CT scan can clearly show the esophagus and the relationship between the neighboring mediastinal organs. Normal esophageal clear boundaries with the neighboring organs, esophageal wall thickness of no more than 5mm, such as the increase in esophageal wall thickness, with fuzzy boundaries around the organ, then the existence of esophageal lesions.
Other test to diagnosed Esophageal cancer. Application of toluidine blue or iodine staining in vivo endoscopy on early diagnosis of esophageal cancer have a certain value. This tests is easy to locate and determine the scope of accurate cancer.
