What are the common examination methods of esophageal cancer

summary

Uncle recently felt very painful when eating and swallowing. Sometimes he couldn't eat at all. He doubted whether he had esophageal cancer, so he went to the hospital to do some related examinations. Now let me talk about the common examination methods for esophageal cancer.

What are the common examination methods of esophageal cancer

First: esophageal endoscopic ultrasonography (EUS): in recent years, EUS has been gradually applied in clinical practice. However, due to the expensive equipment, it will not be widely used in the foreseeable future. Under normal circumstances, the first layer of mucosa is echogenic, the second layer of muscularis mucosa is the dark area, and the third layer of submucosa has echo.

Second: X-ray barium radiography: X-ray barium radiography is the main means of diagnosis of cardiac cancer. In the early stage, there were slight mucosal changes, small ulcer niches and less obvious and constant filling defects. In early cases, the diagnosis can only be made by fibergastroscopy combined with cytology and biopsy pathology. The X-ray findings of the late cases were clear, including soft tissue shadow, mucosal destruction, ulcer, niche, filling defect, tortuous and narrow cardia passage, lower esophageal invasion, and infiltration of gastric fundus and large and small curvatures. The wall of the stomach was stiff and the volume of the stomach was reduced.

Third: esophageal exfoliative cytology examination: the method of esophageal exfoliative cytology examination is simple, the pain of the examinees is small, and the false positive rate is low. Practice has proved that it is the most feasible method to conduct large-scale census in high incidence areas, and the total positive detection rate is about 90% (94% of esophageal cancer). 2% and 82% respectively. The false positive rate was less than 1%, and the false negative rate was 10%.

matters needing attention

Although esophageal cancer is a relatively serious disease, but there is still the possibility of cure, in line with the principle of early know and early treatment, we should also have regular examination, esophageal cancer can do the above examination, early detection of disease, early treatment.
