Early detection of esophageal cancer

We know that the inspection methods mainly include:

X-ray esophagography, such as routine barium swallowing examination, often can not find early cancer, so it is necessary to carry out patient and meticulous esophageal mucosal examination under barium swallowing to find the subtle changes of mucosa; this is a

A practical method is often used to determine the location and size of esophageal cancer, the X-ray image type of esophageal cancer and the time of illness.

Esophageal dragnet cytology is an important method to find early esophageal cancer, which can be found in esophageal cancer that cannot be seen on X-ray film. It is often used for screening in areas with high incidence of esophageal cancer.

The positive rate of screening can be as high as 60%~80%.

Esophagoscopy is a routine examination method to find carcinoma in situ and early cancer. It can not only directly see the specific situation of cancer in esophagus and determine the location of cancer, but also be in the place where cancer is suspected.

Bite the living tissue for pathological examination. If necessary, the esophageal mucosa can be stained, which is helpful to find abnormal mucosa and take biopsy for pathological examination, so as to improve the correct diagnosis rate. along with

Among the above three methods, X-ray esophagography is painless and easy to accept, but it still depends on cytological or pathological examination to determine whether it is the pathological type and cancer cell of cancer.

CT, magnetic resonance imaging, esophageal cavity ultrasound examination and other methods are helpful to further understand the cancer situation, and can be used when necessary and conditional.

X-ray examination of esophageal barium swallowing should be performed in any suspicious case. X-ray signs of early esophageal cancer are very suspicious under the following circumstances:

Local mucosal folds are thickened and ruptured.

Localized esophageal wall stiffness.

Small local filling defects.

Small niche shadow. In the late stage, most of them are filling defect, lumen stenosis or obstruction. Patients with high suspicion but uncertainty should undergo esophagoscopy and biopsy. Cytological examination of esophageal dragnet shedding and radioactive isotope 32P are helpful for early diagnosis of cancer.
