What does gastroscope mainly check?

Question 1: What is gastroscopy? Gastroscope is a medical examination method and also refers to the instruments used in this examination. With the help of a slender and soft tube, it extends into the stomach, so that doctors can directly observe the lesions of esophagus, stomach and duodenum, especially for minor lesions.

Gastroscope is a slender tube with a diameter of about 1 cm wrapped in black plastic, and the front end is equipped with an endoscope, which extends from the mouth into the esophagus → stomach → duodenum of the subject. Using the strong light from the light source, the light is turned by the optical fiber, so that the doctor can clearly observe the health status of each part of the upper digestive tract from the other end. If necessary, a small hole can be made in the gastroscope and a clip can be inserted for biopsy. The whole examination time is about 10 minutes, and it takes 20 to 30 minutes if biopsy is done.

For gastroscopy, in order to see the mucosa of digestive tract clearly, the examined part must be clean, that is, there is no food or blood clot residue. If you have a gastroscope in the morning, don't eat, drink or smoke after 8 pm the day before the examination. Eat less residue and digestible food for dinner the night before. Because patients can change the color of gastric mucosa even if they drink a small amount of water, for example, in the natural lesions of obvious atrophic gastritis, the gastric mucosa can turn red after drinking water, which leads to diagnostic errors. Gastric lavage must be carried out the night before the examination, and the contents of the stomach must be thoroughly cleaned until the reflux liquid is clear. After gastric lavage and before pulling out the gastric tube, the patient takes a supine position with his head down and his feet high, so that the residual liquid in the stomach can be completely discharged. Gastric lavage is not allowed on that day, because gastric lavage will change the color of gastric mucosa. At the same time, in order to reduce saliva secretion, reflex and tension, atropine 0.5 mg and diazepam 10 mg or lumina 0. 1 g were given before examination, and defoamer 2 ~ 3 ml was drunk after injection.

Gastroscopy is an invasive procedure. A slender tube wrapped in black plastic with a diameter of about 1 cm is inserted into the throat, which is unbearable and the patient is prone to fear.

Therefore, scientists invented the capsule endoscope (intelligent capsule digestive tract endoscope system) without any anesthesia. Patients can take a small "capsule" instead of gastroscope for examination, and can examine the stomach, large intestine and small intestine, and clearly take 70,000 to 80,000 photos of human gastrointestinal diseases. The front end of the capsule endoscope is transparent and spherical, and there is a miniature digital camera and six flashlights inside. You can take clear photos in the dark digestive tract, but the price is very expensive, generally 2000-3000, which is 5- 10 times that of ordinary gastroscope.

Question 2: What should I pay attention to when doing gastroscopy? 1, prepare in advance, and don't eat or drink at least 8 hours before the exam. (Generally, food is prepared in advance in the hospital on an empty stomach the next morning. The food in the stomach easily affects the doctor's diagnosis and easily causes nausea and vomiting. In order to reduce throat discomfort, medical staff will spray anesthetic on the patient's throat 3 minutes before the examination.

2. Painless gastroscope is an anesthetic used for general anesthesia. Anesthesia time is very short, mainly depending on your gastroscope time. /kloc-you can wake up in 0/0 minutes. Of course, it is safe under the supervision of an anesthesiologist. Gastroscope can observe duodenum. At present, the most advanced gastroscope in clinic is electronic gastroscope. Electronic gastroscope has good image quality, large screen, clear image, high resolution and slender and soft body.

3. During the inspection, first put on loose clothes, take a left lying position, and slightly bend your legs. When the doctor puts the gastroscope into the patient's mouth with a plastic device, he should relax and swallow slightly, so that the gastroscope can smoothly enter the esophagus through the throat. When passing through the throat, there will be a feeling of pain and vomiting for a few seconds, which is a more uncomfortable moment during gastroscopy.

When making a diagnosis, the doctor should not swallow, but inhale through the nose and exhale slowly in the mouth, so as to successfully complete the examination. Some people feel flatulence and nausea because air enters the stomach with the tube. If you feel pain and discomfort, please make a gesture to the medical staff, and never grab the pipe or make a sound.

5. After the treatment, don't eat within 0 ~ 2 hours after the 65438+ examination. If there is no uncomfortable feeling in the throat, you can drink water first. If you don't choke, you can eat soft food first to avoid esophageal or stomach bleeding caused by rough food. Some people will have a brief sore throat and foreign body sensation, which can be recovered in 1 to 2 days.

Generally, painless gastroscopy has been done in the later stage, which may lead to poor appetite and other physical discomfort in the next few days because of personal physical reasons and anesthesia incompatibility. Suggest a painful gastroscope. Painful gastroscopy is not particularly complicated, nor is it really painful, but it is uncomfortable when oropharyngeal intubation is performed. The whole process lasts a few minutes. Don't be too sensitive after gastroscopy and don't have any adverse reactions. Some are psychological and personal.

Question 3: Who needs gastroscopy? First, epigastric pain, either light or heavy, especially for patients with a long course of disease and patients over 50 years old. Second, unexplained loss of appetite and weight loss. Third, patients with hematemesis or melena. Fourth, the upper abdominal mass. Fifth, swallowing is unfavorable or there is obstruction when eating. Six, has been diagnosed as atrophic gastritis. Seven, patients with peptic ulcer, gastroscopy can clearly understand the bleeding location, size, activity, etc. It can also detect whether there is Helicobacter pylori in the stomach at the same time, which provides important materials for thorough treatment. After treatment, we can know the effect of treatment by reviewing gastroscope. Eight, patients with gastric and duodenal polyps can differentiate benign and malignant lesions through gastroscopy and biopsy. It can also be effectively treated by gastroscope, avoiding the pain of surgery. Nine, after gastric surgery, gastroscopy patients can find possible cancer as soon as possible. X. Patients with acid reflux and heartburn can know whether there is esophagitis and its scope, nature and severity through gastroscope. Eleven, other parts of the body found metastatic cancer need to find the primary focus. 12. Swallow foreign objects (such as pins, buttons, rings, steel needles, keys, jujube stones, fishbones, necklaces? Patients can be removed through gastroscope and supporting tools without surgery. Thirteen, people with a family history of cancer, gastric cancer, esophageal cancer high incidence areas should do routine physical examination of gastroscope.

Question 4: What can a gastroscope detect? Gastroscopy Objective Gastroscopy is of special significance for the diagnosis and treatment of digestive tract diseases. Never underestimate gastroscopy, which is an important clinical examination item in gastroenterology. There are generally three clinical purposes: ① accurate diagnosis: direct vision of stomach diseases through fiberoptic gastroscope to determine the location and nature of the diseases. Biopsy is helpful to diagnose gastric malignant tumor, chronic gastric and duodenal diseases, unexplained upper gastrointestinal bleeding, pyloric obstruction and other diseases. ② Observation of curative effect: Follow-up or observation of curative effect on patients with gastric and duodenal diseases. ③ Treatment: At the same time of examination, endoscopic treatment such as hemostasis, forceps removal of foreign bodies and electrocoagulation resection of polyps was performed.

Question 5: What is the clinical significance of gastroscopy? The main examination of gastric diseases is gastroscopy, which can not only directly observe the surface of gastric mucosa with naked eyes, but also do pathological biopsy of gastric mucosa at the same time to confirm the correctness of the diseases seen. The clinical significance of judging the degree of chronic gastritis and whether there is intestinal metaplasia and distinguishing between benign and malignant ulcer lesions is as follows: the clinical significance of gastroscopy 1, esophagitis is generally divided into three categories under endoscope: mild, moderate and severe. 2. Esophageal ulcer erosion refers to the defect of esophageal mucosal epithelial tissue. If the lesion reaches submucosa and muscularis propria, it is called ulcer. 3. Esophageal cancer Esophageal cancer is the most common esophageal disease. It accounts for 49.3% of the endoscopic diagnosis of esophageal diseases. 4. Esophageal varices are mostly caused by portal hypertension caused by cirrhosis. It is rare for tumors to compress the superior vena cava. Esophageal varices are blue or cyan, serpentine or hemispherical under endoscope, and distributed along the long axis of esophagus. 5. Gastroscopy of gastric cancer is of great significance for the diagnosis of gastric cancer. On the one hand, early gastric cancer can be found, while benign and malignant ulcers can be distinguished. You can also judge the type of gastric cancer and follow up precancerous lesions. 6, gastric ulcer Gastric ulcer and its healing process in different periods, the performance under gastroscope has considerable variation. The basic morphology of gastric ulcer is mucosal defect, with white fur at the bottom of the ulcer, edema, congestion and other inflammatory reactions at the edge, and mucosal folds are concentrated in the ulcer. 7, duodenitis in endoscopic examination can be seen mucosal congestion, edema, roughness, punctate bleeding, congestion or ecchymosis, punctate or patchy erosion, mucosal vascular exposure or rough folds and nodules. 8. Duodenal ulcer gastroscopy is of great value in the diagnosis and curative effect judgment of duodenal ulcer.

Question 6: The function and harm of gastroscopy: The position and degree of gastritis and gastric ulcer can be clearly judged. That is, to know how the disease is. It has guiding significance for the next treatment and medication. Danger: uncomfortable when doing it. Snuff and tears. I feel sick again, and it hurts a little. That kind of taste, only when you have done it. However, what should be done is still to be done. After all, if you endure the pain for a while, you can get the right medication. Worth it.

Question 7: Why do you want to do gastroscopy? The purpose of gastroscopy is to check the inflammation, bleeding, ulcer, benign tumor and malignant tumor of esophagus, stomach and duodenum, so as to find early gastric cancer and esophageal cancer in time and win valuable treatment time for patients. Gastroscope is a high-definition camera, which can see the true color enlarged images of stomach, esophagus and duodenum. If you have never had a gastroscope within half a year, and are over 40 years old, have a family history of gastric cancer, or have a history of gastric ulcer, or have a high incidence of gastric cancer and ulcers such as melena, you must have a gastroscope. What is your specific situation? Please provide more medical history! Medical things are more complicated and need specific analysis!

Question 8: Under what circumstances do you need to do gastroscopy? If you have pain or flatulence, you need to have a gastroscopy. Soft-skinned intestines and stomach are mainly maintained at ordinary times Pay attention to rest at ordinary times. Diet should be light and nutritious, and avoid spicy, greasy and blunt food.
