The advantage of gastroscopy is that both men and women, old and young, the severity of illness and the amount of bleeding can be checked repeatedly. Patients with severe heart and lung failure and unconsciousness are considered taboo because they can't cooperate with the examination well.
In order to avoid cross-infection of hepatitis virus, the surface antigen of hepatitis B virus should be checked before examination, and special gastroscope should be used for those who are positive.
prescription
1. Gastroscopy is an important method to diagnose gastric and duodenal diseases. If the doctor thinks it is necessary to check, the patient should actively cooperate.
2. Fiber gastroscope technology is very mature, safe and reliable, without too much pain, and patients need not be nervous.
3. Fasting for 8 ~ 10 hour before examination. Take off your false teeth, relax your belt, take off your shoes and go to bed, and take a left position; The injected anesthetic can be swallowed.
4. Breathe smoothly through the nasal cavity during the examination, and don't hold your breath. Try to cooperate with the doctor when inserting the gastroscope and swallow the gastroscope.
5. Eat warm liquid or semi-liquid diet every 1 ~ 2 hours after examination, and return to normal diet the next day.
6. Most of the sore throat caused by examination and a small amount of bleeding after taking gastric mucosa samples can heal themselves, so don't worry. If you have black stool after the examination, you should go to the emergency room for medical treatment.
(Professor Zhang Shenshan from Shanghai Medical University)
Clinical value of gastroscopy Besides clinical diagnosis, I have been doing gastroscopy and treatment since 1982, and so far I have examined tens of thousands of people. Many people are afraid of gastroscopy. According to hearsay, gastroscopy is painful, but they dare not do it. Some patients with upper digestive tract tumors are not examined at the initial stage, and they are diagnosed as cancer at the later stage, which is hopeless. It's really distressing
In fact, the new electronic gastroscope is slim, soft and flexible, and doctors can complete the examination within 3- 10 minutes, with little nausea and no great pain. Next, let me introduce the knowledge about gastroscopy:
Clinical value of gastroscopy
1. provides a diagnostic basis for clinical treatment. Diagnosis helps to choose treatment methods and make the treatment targeted. For example, the medical treatment of benign and active gastric and duodenal ulcers requires anti-ulcer treatment for 4-8 weeks, and then half a dose of anti-ulcer drugs for 6- 18 months; HP infected patients were treated with two, three and four anti-HP drugs for one course of treatment without interruption, and severe patients were treated with another course; If it is diagnosed as a tumor, it is necessary to take radical surgery as soon as possible, with radiotherapy and chemotherapy.
2. To provide reference for the development trend and prognosis of the lesion. Such as: chronic superficial gastritis, most of which have a good prognosis; However, if the active peptic ulcer develops further, it may be accompanied by complications such as pyloric obstruction, perforation and bleeding, which need to be closely observed to prevent accidents. Atrophic gastritis, gastric polyp and recurrent peptic ulcer above moderate level belong to precancerous diseases of gastric cancer. Pathologically, gastric metaplasia, intestinal metaplasia and dysplasia of esophageal mucosa or intestinal metaplasia and dysplasia of gastric mucosa belong to precancerous lesions. Precancerous diseases and precancerous lesions need active treatment, close observation and regular review to prevent the development of lesions. Even if cancer occurs, it can be found and cured early.
3. Provide evidence for the doctor to check the condition. Gastroscopy not only provides a scientific diagnosis for patients and a basis for doctors' treatment, but also provides a scientific basis for protecting doctors' interests and preventing medical disputes. The images and written materials examined in our endoscopy room are stored in the hard disk of the computer, which can be used by patients and doctors concerned.
4. It can reduce the psychological burden of patients. Some patients are hypochondriac and suspect that they have digestive tract tumors. The best prescription to treat this hypochondria of digestive tract tumor is a gastroscopy diagnosis certificate to exclude digestive tract tumor.
5. Hard indicators for objective inspection of scientific research projects. For example, the clinical observation of drugs for the treatment of upper gastrointestinal mucosal lesions and the control group need gastroscopy before and after medication. Gastroscopy is the main objective index to reflect the curative effect.
Indications of gastroscopy
1. Anyone suspected of esophageal, gastric and duodenal diseases cannot be diagnosed by comprehensive examination (including X-ray examination).
2. Pain behind the sternum ... >>
Question 2: What are the steps to do gastrointestinal examination? If you have a gastrointestinal examination, be careful not to eat the day before the examination. If necessary, you need to take some laxatives. At the same time, it is necessary to get the diagnosis and treatment of the gastroenterology department of the hospital and check under the guidance of a doctor.
Question 3: What specific tests should be made for stomach diseases? Stomach disease is actually a general term for many diseases. They have similar symptoms, such as epigastric discomfort, pain, fullness after meals, belching, acid reflux, and even nausea and vomiting. Clinical common stomach diseases include acute gastritis, chronic gastritis, gastric ulcer, duodenal ulcer, gastroduodenal compound ulcer, gastric polyp, gastrolith, benign and malignant tumors of the stomach, gastric mucosal prolapse, acute gastric dilatation, pyloric obstruction and so on. So what tests should stomach diseases do? 1. Gastroscopy directly penetrates the stomach from the mouth through the fiber tube. The probe can directly photograph the surface of the stomach, and can know in detail whether there is congestion, edema, erosion, ulcer and so on. Preparation before the exam: an empty stomach exam. Advantages and disadvantages: This is the most accurate inspection at present. There will be some discomfort during the examination. 2. Ultrasonic examination The principle of ultrasonic diagnosis is to use the pulse reflection of ultrasound to determine whether there are lesions in deep tissues, which has high diagnostic value for the lesions of abdominal liver, gallbladder, pancreas, spleen and other substantive organs, and also has certain diagnostic value for gastric cancer with obvious masses. The gastrointestinal tract is a hollow organ, and the ultrasonic reflection is anechoic. The main lesions of the gastrointestinal tract, such as tumors and ulcers, are also anechoic or hypoechoic, and there is no obvious contrast during examination. Therefore, it is difficult for ultrasound to find ulcers with small mucosal defects, but ultrasound cannot find mucosal erosion. It is important that ultrasound examination can not detect early gastric cancer. Preparation before the exam: an empty stomach exam. Advantages and disadvantages: painless, unable to understand the situation of bacteria in the stomach and whether cancer occurs, insensitive to subtle symptoms. 3. Helicobacter pylori detection Helicobacter pylori is a cause of stomach diseases, such as redness, erosion and even ulcers on the inner surface of the stomach, which are basically caused by this pathogen. Therefore, if we find out whether we are infected with Helicobacter pylori, we can diagnose the causes of stomach diseases and make corresponding treatment plans. Preparation before inspection: No special precautions. Advantages and disadvantages: no pain, but little information, only know the situation of Helicobacter pylori, and have no effect on edema, congestion, erosion, plaque and other conditions. 4. Barium meal examination Patients with gastric diseases take contrast agent. After a period of time, the contrast agent fills the whole digestive tract through the peristalsis of the digestive tract. Using X-ray examination, we can understand the morphological characteristics of various organs of the digestive tract. Preparation before the exam: an empty stomach exam. Advantages and disadvantages: I feel a little uncomfortable, and I can know the signs of various organs in the digestive tract in detail.
Question 4: How much does it cost to have a stomach examination? It takes more than 500 to do a gastroscope and helicobacter pylori examination. You can swipe your medical insurance card for the examination.
Question 5: What preparations should be made for a comprehensive examination of the stomach and intestines? I have to have a gastroscope. Don't eat the night before, check on an empty stomach. It can also be inflammation, see if there is an ulcer, and prescribe the right medicine.
Question 6: What are the items of gastrointestinal examination? Gastric cancer is one of the most common malignant tumors in China, and its incidence ranks first among all kinds of tumors in China. More than 70% of early gastric cancer has no obvious symptoms, and some stomach discomfort has not attracted enough attention. If we don't pay attention to the health of the stomach, we don't know how many potential risk factors there will be. With the development of the disease, nonspecific symptoms like gastritis or gastric ulcer may gradually appear. If there are symptoms such as pantothenic acid, anorexia and dyspepsia, we should pay attention to preventing gastrointestinal diseases through regular health examination. Then, stomach discomfort 1) stomach carbon 14 check: check whether there is Helicobacter pylori (HP) infection. HP infection can lead to gastritis, gastric ulcer and gastric cancer. You need to take one urea (14C) capsule orally on an empty stomach, wait for more than 20 minutes, and then blow into a small bag for about one to three minutes until it is prompted to change color. 2) B-ultrasound examination of stomach and abdomen: B-ultrasound examination can well find out the situation of your stomach and whether the surrounding organs have changed. The dinner on the day before the inspection should be light and less residual food. Eating breakfast and drinking water should be forbidden in the morning of examination to reduce the interference of gastrointestinal contents on ultrasonic beam. 3) Intestinal-fecal routine: including fecal occult blood test (normal is negative. If the test result is positive, consider gastrointestinal bleeding caused by gastrointestinal malignant tumor, ulcer disease and liver cirrhosis. ) and fecal cells (red blood cells are normally invisible. White blood cells are rare. The appearance and increase of red blood cells consider dysentery, enteritis, colon cancer and hemorrhoid bleeding. For leukocytosis, items such as enteritis and bacillary dysentery should be considered, and the intestinal situation should be found in time mainly through inspection. Take a piece of fresh feces about the size of broad beans with bamboo sticks or sawdust, put it in a carton specially reserved for specimens, write down your name and send it for inspection immediately. I hope the above introduction can help you understand the gastrointestinal examination items. Please learn more about the physical examination items through the network platform of the People's Physical Examination Center.
Question 7: How to check the gastrointestinal function? If you have a gastrointestinal examination, be careful not to eat the day before the examination. If necessary, you need to take some laxatives. At the same time, it is necessary to get the diagnosis and treatment of the gastroenterology department of the hospital and check under the guidance of a doctor.
