Esophageal exfoliation cytology

The biggest feature of this inspection method is that the subject has less pain and high accuracy. Practice has proved that the total positive rate of esophageal cancer detected by this examination in the high-incidence area of ​​esophageal cancer is as high as 90%, which is the first choice for early diagnosis of esophageal cancer.

Chest CT scan

This test is helpful for the staging, resection judgment, and prognosis estimation of esophageal cancer

X-ray barium meal imaging

This examination is not easy to detect early esophageal cancer, so the doctor will ask the patient to swallow the barium in several small mouths during the test, and then observe and double-contrast air-barium to find whether the esophageal mucosa is thickened, tortuous or interrupted in a broken line. Moreover, it is easy to find early signs of esophageal cancer such as whether there is a defect in the edge of the esophagus, or a localized wall stiffness, and barium retention.

Fiber endoscopy

This examination has become a routine clinical diagnosis method for digestive tract diseases such as esophageal cancer and gastric cancer. This device can be bent, the visual range of observation is wide, and the accuracy is high. In the early stage of esophageal cancer, the detection rate of fiber endoscope can reach over 85%.

Esophageal endoscopic ultrasonography

In recent years, endoscopic ultrasound examination of the esophagus has gradually been used in clinical practice. Its advantage is that it can accurately measure the depth of the lesion infiltration in the esophageal wall; it can measure abnormally enlarged lymph nodes outside the wall; it is easy to distinguish the location of the lesion on the esophageal wall.
