How is the stomach examined? Gastroscopy is very common.

Most of us have bad stomachs and various stomach problems, which are closely related to our daily diet and lifestyle. If you have a bad stomach, you should get checked in time. The most common check is gastroscopy. Do not eat the night before the check.

1. Gastroscopy

Gastroscopy uses a slender tube with a diameter of about one centimeter and a light-conducting fiber wrapped in black plastic. The front end is equipped with an endoscope and is inserted through the mouth into the subject's esophagus, stomach, and duodenum. The strong light emitted by the light source can bend the light through the light-conducting fiber, allowing the doctor to clearly observe the health status of various parts of the upper digestive tract from the other end. If necessary, a clip can be inserted through the small hole on the gastroscope for biopsy. The entire examination takes about 10 minutes, and if a biopsy is required, it will take 20 to 30 minutes.

2. Clinical advantages

Capsule endoscopy is a new medical examination method. Due to its small size and convenience, it has been widely used in clinical practice. Its advantages in clinical use are:

Expanded field of view: True color image capture of the entire small intestine segment, clear microscopic view, breaks through the blind spot of small intestine examination, and greatly improves the diagnosis and detection rate of digestive tract diseases.

Safety and hygiene: The capsules are disposable, effectively avoiding cross infection. The capsule shell is made of corrosion-resistant medical polymer material, which is non-toxic and non-irritating to the human body and can be safely excreted.

Comfortable and relaxed: You only need to swallow a capsule. The examination process is painless, non-invasive, wire-free, and does not require anesthesia, and will not interfere with your normal work and life.

Easy to operate: Say goodbye to cumbersome operations, three steps are clear and simple. Doctors can diagnose the condition simply by playing back the images captured by the capsule.

3. Notes

During a gastroscopy, in order to clearly see the mucous membrane of the digestive tract, the area being examined must be very clean, with no food or blood clots remaining. If you have a gastroscopy in the morning, do not eat or drink, and do not smoke after 8 pm the night before the examination. Eat food with less residue and easy to digest for dinner the day before. Because even if the patient drinks a small amount of water, the color of the gastric mucosa can change. For example, in the case of significant atrophic gastritis, the gastric mucosa can turn red after drinking water, which can lead to errors in diagnosis. If the gastroscopy is performed in the afternoon, the patient can drink some sugar water before 8 am that day, but cannot eat anything else and must not eat at noon. Such as patients with pyloric obstruction. Gastric lavage must be performed the night before the examination, and the gastric contents must be thoroughly washed out until the flushing fluid is clear. After gastric lavage and before the gastric tube is removed, the patient should lie in a supine position with his head low and feet high to allow the remaining fluid in the stomach to be completely discharged. Gastric lavage should not be performed on the same day because it can change the color of the gastric mucosa. If a barium meal examination has been done, the barium may be attached to the gastrointestinal mucosa, especially the site of ulcer lesions, making fiber gastroscopy diagnosis difficult. Therefore, gastroscopy must be performed 3 days after the barium meal examination.

At the same time, in order to reduce saliva secretion, reduce reflexes and reduce tension, inject 0.5 mg of atropine and 10 mg of diazepam or 0.1 g of luminal 15 to 30 minutes before the examination, and drink 2 to 3 ml of defoaming agent after the injection.
