Introduction to two main diagnostic methods for gastric cancer

After the symptoms of suspected gastric cancer appear, it is necessary to go to a regular hospital for gastric cancer diagnosis in time, so as to more accurately determine whether you have gastric cancer and treat gastric cancer as soon as possible. It is very important for gastric cancer patients. What are the main diagnostic methods for gastric cancer ? The following will tell you about the main diagnostic methods for gastric cancer.

In general, the main diagnostic methods for gastric cancer are:

1. Gastroscopy

This method of diagnosing gastric cancer relies on optical fibers and camera systems to observe the conditions in the gastrointestinal cavity. The examination is intuitive and vivid. It can comprehensively observe the morphology, color, texture and peristalsis of the lesions, and can also clearly display some tiny lesions. At the same time, gastric wall tissue can be taken for pathological examination through the biopsy hole of the gastroscope. In addition, some lesions can also be treated through gastroscopy. However, gastroscopy requires oral intubation, and patients feel uncomfortable during the examination. If local stenosis is encountered during the insertion of the scope, the scope body cannot pass through, and the situation at the distal end of the stenosis cannot be clearly determined. This is another shortcoming of gastroscopy.

2. X-ray barium meal examination

The diagnostic method for this type of gastric cancer is to first let the patient take a drug that is not permeable to X-rays, barium sulfate. After the barium sulfate is mixed into a paste, it can be evenly applied to the surface of the gastric mucosa. If the patient also takes a drug that can produce bubbles, gas is produced in the stomach, causing the stomach cavity to swell. In this way, it is possible to observe whether the mucosa is smooth and whether the folds of the stomach are intact under X-rays, observe the process of taking barium, and apply local pressure to the abdomen to see the flow of barium, and understand the peristalsis of the gastrointestinal tract. However, if the barium itself has large particles, is unevenly applied, and is not carefully observed, some minor lesions are easy to be missed. In addition, X-ray barium meal contrast can only observe morphology, peristalsis, etc., and cannot be biopsied, so the local pathological conditions are unknown.

The above are the main methods for diagnosing gastric cancer. I believe everyone should have a certain understanding of this. Once diagnosed with gastric cancer, you must go to the hospital for treatment immediately in order to control the deterioration of the disease in time and recover your health as soon as possible.
