What are the four gastric functions

There are many patients with gastric diseases in life. The main cause of gastric diseases is improper diet, such as overeating or long-term irregular eating time, etc. In clinical examination of gastric diseases, the main thing is the four gastric function tests. Through this test, we can understand the condition of the stomach in time, and this test method will also appear in some physical examinations. So what are the four gastric function tests?

First, what are the four items of gastric function? C14 breath test. This method is used to detect Helicobacter pylori. Helicobacter pylori is one of the causes of stomach diseases. Redness, swelling, erosion, and even ulcers on the inner surface of the stomach are basically caused by this bacterium. Therefore, by finding out whether you are infected with Helicobacter pylori, you can diagnose the cause of your stomach disease and make a corresponding treatment plan. Ultrasonography. The principle of ultrasonic diagnosis is to use the reflection of ultrasonic pulses to determine whether there are lesions in deep tissues. It has a high diagnostic value for lesions of solid organs in the abdomen, such as the liver, gallbladder, pancreas, and spleen. It also has a certain diagnostic value for gastric cancer with obvious masses. The stomach and intestines are hollow organs and are anechoic in ultrasound reflection. Major gastrointestinal lesions, such as tumors and ulcers, are also anechoic or hypoechoic and cannot produce obvious contrast during examination. Therefore, ulcers with very small mucosal defects are difficult to detect with ultrasound, and mucosal erosions cannot be detected with ultrasound. Crucially, ultrasound examinations cannot detect early-stage gastric cancer.

Second, barium meal examination. The patient takes contrast agent. After a period of time, the contrast agent passes through the peristalsis of the digestive tract and fills the entire digestive tract. X-ray examination can be used to understand the morphological characteristics of various organs in the digestive tract. Gastroscopy. The probe is inserted directly into the stomach through a fibrous tube from the mouth. The probe can directly photograph the surface conditions inside the stomach and provide detailed information on whether there is congestion, edema, erosion, ulcers, etc.

What are the four items of gastric function? The above content introduces them. What are the precautions for the four items of gastric function examination? Pay attention to the following precautions: Stop taking drugs that are not X-ray-painted or affect gastrointestinal function, such as bismuth subcarbonate and calcium gluconate, 1-2 days before the examination. Eat easily digestible food with less residue one day before the examination, and fast after dinner. Patients with gastric retention should undergo gastric lavage the night before examination. The purpose is to clear the gastric contents and facilitate barium meal examination. Perform a full digestive tract barium meal examination and take 100g of barium sulfate powder at 2 a.m. on the examination day, mixed with 200-300ml of warm water. Explain to the patient that swallowing barium is harmless to the body, it will not be absorbed and will be excreted in the stool after taking it. You will have white dry stool 1-2 days after the barium meal examination, so don't be nervous. Pregnant women under 3 months of age are prohibited from undergoing this examination.
