First, the inspection esophageal function: 1) esophageal motor function tests: A) Determination of esophageal pressure, Apply to suspected patients with esophageal motility disorders; B) remove acid test for the exclusion of esophageal body acid wiggle efficiency. 2) Determination of gastroesophageal reflux: A) esophageal acid perfusion test; B) 24-hour esophageal pH monitoring; C) lower esophageal sphincter pressure test. Second, Imaging diagnosis: 1) X-ray barium meal examination: is the diagnosis of esophageal tumors and cardiac one of the important means for the study of early esophageal cancer can provide reliable data and cytology and esophageal endoscopy, can improve the accuracy of diagnosis of esophageal cancer. Esophageal cancer X-ray barium meal examination to determine not only lesion location, length and degree of obstruction, there needs judgment esophageal lesions and the invasion of foreign invasion.
2) CT: CT scan can clearly show esophagus with the neighboring mediastinal organs, but found it difficult early esophageal cancer. Will CT and X-ray examination of combining will help in the diagnosis and staging of esophageal cancer rise in the level of.
Third, esophageal cytology examination: Esophageal exfoliative cytology method is simple, convenient operation, safety, patients suffering small, and an accuracy rate of more than 90%, esophageal cancer is an important method for large-scale census. But for esophageal bleeding and bleeding tendency, or with esophageal varices should taboo for esophageal dragnet cytology; of esophageal cancer X-chip see a deep esophageal ulcer or with hypertension, heart disease and late pregnancy, should Shenxing esophageal dragnet exfoliated cells checks on the general situation worse, the patients are too frail patients should first improve the general status later for a check; merger upper respiratory tract and acute upper gastrointestinal inflammation, infection control should be re-inspection. Combined X-ray barium meal examination in the diagnosis of esophageal cancer can be used as the basis, the majority of patients suffering from esophageal endoscopy. But esophageal stenosis have obstruction, so this method can not be carried out esophageal endoscopy.
4. Esophagoscopy: Esophagoscopy fiber has been widely used in the diagnosis of esophageal cancer. Esophagoscopy can be directly observed tumor size, shape and location, for the clinician to provide a basis for treatment, but also to make the lesion sites or mirror brush biopsy examination. Esophagoscopy exfoliative cytology with the combination of esophageal cancer is the ideal diagnostic method.
5, differential diagnosis: In addition to the differential diagnosis of esophageal cancer history, symptoms and signs, to a large extent depend on the X-ray and endoscopic examination, the final diagnosis to confirm the histological diagnosis. Take benign esophageal cancer and esophageal cancer and the other for identification.
