How to do gastroscopy? How to practice gastroscopy?

Gastroscopy is a medical examination method and also refers to the equipment used in this examination. It uses a thin, flexible tube that extends into the stomach so that doctors can directly observe lesions in the esophagus, stomach, and duodenum, especially for tiny lesions.

Gastroscopy can directly observe the real condition of the examined site, and can further confirm the diagnosis by pathological biopsy and cytology examination of the suspicious lesion site, which is the preferred examination method for upper gastrointestinal lesions.

There are two kinds of gastroscopy, one is that cheap people have to endure hardship, make an appointment at the hospital two days in advance, and the doctor will give you the medicine you need to take back to drink, and then defecate, and you must drain your stomach and intestines before you can do it. 2 are **** masters who are not guilty, they are anesthetics, and the process is the same.

Gastroscopy is a thin, flexible tube inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach, and duodenum, especially for minor lesions. Generally, no reservation is required. In order to clearly see the mucous membrane of the digestive tract, it is necessary to make the area to be examined clean, that is, there is no food and no blood clots.

If you have a gastroscopy in the morning, you should not eat food or drink after 8 p.m. on the night before the examination, and smoking is prohibited.

Before ultrasound gastroscopy, the liver function and hepatitis B, hepatitis C, syphilis, AIDS laboratory tests should be improved, the patient needs to be fasted for more than 4-6 hours before the examination, eat less residue and easily digestible food one night before the examination, and inform the patient of the purpose, necessity, related risks and matters that need to be paid attention to before the examination, eliminate the patient's concerns, and sign the informed consent form. 15-30 minutes before the examination, oral defoamer, intramuscular injection of scopolamine, intramuscular injection or slow intravenous injection of diazepam in patients with mental stress, and local anesthesia and infiltration with lidocaine glue in patients undergoing upper gastrointestinal examination. In the process of endoscopic ultrasound of the upper gastrointestinal tract, the patient is placed in the left lateral decubitus position, with both lower limbs slightly flexed, the collar is unfastened, the belt is relaxed, and the head is tilted back.

Operation steps: After the endoscopic ultrasound is inserted into the digestive tract, the direct contact method, the water bladder method and the water bladder method combined with the airless water filling method can be used to scan the lesions, tumors and adjacent organs of the gastrointestinal tract, combined with Doppler, the endoscopic ultrasound can check the blood flow velocity and blood flow, and can show the direction of blood flow.

I do a gastroscopy with pain, first of all, I have to open a list in advance, do five tests of liver function, and blood tests, and some hospitals also need to do an electrocardiogram examination, which seems to be related to age and medical history. Then go to the gastroscopy room according to the appointment time, and a small bottle of medicine will be given to drink before, and the first night is not allowed to eat, including water. When you get to the gastroscopy room, the staff will use a strap to open your mouth, and then it's time to intubate, but you also need to cooperate with swallowing, which can be fast and less sinful.

When doing gastroscopy, you must first go to the hospital**, to the gastroenterology department or gastroenterology department of the hospital**. Blood tests are required before gastroscopy, mainly to see if there is hepatitis B. Gastroscopy can only be done after the examination results are normal.

In order to alleviate the pain and discomfort when the gastroscope is extended over the throat, local anesthesia can now be performed for gastroscopy. That is, before the gastroscopy, we will let the patient drink the anesthetic and defoaming agent.

When entering the examination room, the patient lies down in the left decubitus position and bites the dental pad, with a plate on the side of his mouth to catch the saliva coming out of the gastroscopy. The doctor inserts the tube into the person's mouth and tells the person to swallow it when it reaches the throat so that the tube can reach the esophagus.

When the gastroscope reaches the point where it needs to be examined, the doctor will start the examination. At this point, the patient will experience some discomfort, but this discomfort is not very intense and is completely tolerable. Just a symptom of nausea and vomiting. At this time, the patient should take deep breaths and cooperate with the doctor.

**Gastroscopy is the use of ultrasound principle to diagnose and detect digestive system diseases, is a leading technology of the times of instruments and equipment. In particular, the use of instant gastrointestinal ultrasound additives, no intubation, no injury, ** bitter, in a short period of time can be a variety of acute and chronic, superficial, atrophic gastritis, gastroduodenal ulcer soup, gastric prolapse, acute and chronic colitis.

It's ok, just a little uncomfortable performance.

Do I need a CT scan before gastroscopy?

The basic process of doing a gastroscopy is as follows:

1. Generally, before the examination, there will be precautions about not eating, drinking water, etc. for at least 8 hours before the examination. In order to reduce throat discomfort before the examination, the medical staff will spray anesthetic on the throat of the patient 3 minutes before the examination.

2. During the inspection process, first change into loose clothes, take the left side lying position, and bend your legs slightly. When the doctor inserts the gastroscope through the plastic device contained in the examinee's mouth, he should relax his whole body and swallow slightly, so that the gastroscope can pass through the throat and enter the esophagus. There will be pain for a few seconds when passing through the throat and you will want to vomit, which is the more uncomfortable time during the gastroscopy.

3. When the physician is making a diagnosis, do not swallow, but inhale through the nose and exhale slowly in the mouth so that the examination can be completed smoothly. Some people feel bloated and nauseous as air travels through the tube into their stomach. If you feel pain or discomfort, make a gesture to your health care provider and don't grab the tube or make a sound.

4. After-the-fact treatment, do not eat within 1 to 2 hours after the examination, if the throat does not feel uncomfortable, you can drink water first; If there is no choking, you can eat soft food first to avoid bleeding from the esophagus or stomach caused by coarse food. Some people have a brief sore throat or a foreign body sensation that usually resolves in 1 to 2 days.

The preparation for gastroscopy is relatively simple, mainly including the following points: 1. Past history and vital signs, to see if the patient has serious diseases, such as myocardial infarction, angina, more serious cerebrovascular disease, etc., blood pressure should also be measured, and electrocardiogram should be done to assess whether the patient can withstand gastroscopy or gastroscopy. 2. Some hospitals also need to be tested for infectious diseases, such as hepatitis.

3. Before gastroscopy, you should have an absolute fasting stomach, no food or water, which is conducive to observation. In addition to this, the drug should be swallowed before the examination, which has an anesthetic effect, which can both reduce side effects and reduce foaming in the esophagus, making it easier to observe.

Gastroscopy is an endoscopy that passes through the mouth or nose to the esophagus and finally to the duodenal bulb. During the gastroscopy, the patient should take the left decubitus position, open the mouth, wear a mouth pad and a saliva bag, and cooperate with the doctor to swallow the mouth pad and saliva bag when getting off the gastroscopy, so that the saliva can flow out naturally. For patients, there may be some uncomfortable feelings.

Therefore, gastroscopy can be done under general anesthesia, which is less painful and easier to accept.

Gastroscopy is the easiest, safest and most effective way to detect gastrointestinal inflammation, ulcers, tumors and precancerous lesions. But after all, gastrointestinal endoline examination is an invasive examination method, which has certain discomfort and complications, and therefore, many people are afraid of this examination, resulting in some gastrointestinal lesions and even swelling cancer can not be diagnosed early, and delay the best time.

Nowadays, medicine is developed, and there are a variety of gastroscopy methods that can be performed, such as traditional gastroscopy and ** gastroscopy. **Gastroscopy is performed in the state of "shallow anesthesia", the patient does not feel anything, and the examination is over after a gentle sleep. Moreover, now that the gastroscopy equipment has been innovated and upgraded, lesions as small as 1-2 mm cannot escape the "sharp eyes" of new technology, and large and small lesions can be accurately identified.

Gastroscopy is a thin, flexible tube inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach and duodenum, especially for minor lesions.
