What diseases require gastroscopy? Anyone suspected of having esophageal inflammation (both chemical and reflux), esophageal ulcer, tumor, stricture, esophageal hiatal hernia and esophageal varices; suspected inflammation of gastric mucosa (acute and chronic gastritis, atrophic gastritis), gastric ulcer, gastric tumor; duodenal inflammation, ulcer, diverticulum, tumor, duodenal papillary lesion; foreign body in the upper gastrointestinal tract are all indications for gastroscopy. What can cause your discomfort? Before the gastroscopy, your doctor will routinely perform an electrocardiogram, will instruct you to fast absolutely for more than 8 hours, and will ask you to take care of your breathing and swallowing. If it is a painless gastroscopy, you will also be asked a lot of medical history, surgical history, drug allergy history, etc. These are necessary, but may cause you anxiety, plus absolute fasting will bring you hunger, dry mouth, smoking addiction, etc. If you have diabetes, you may also have heartburn and sweating. The lack of understanding of the condition and the gastroscopy process can cause you to be confused, and the nausea and dryness caused by the mirror passing your throat is what you show, and the movement of the mirror in your abdomen can cause you to have nightmares. Do you know about gastroscopy? Endoscopy was conceived by German Bozzini as early as 1805, and the first fiberoptic gastroduodenoscope was made by American HirShchowitz in 1957. 1983, WelchAllyn invented the electronic endoscope. At present, the gastroscope has a field of view of 120 degrees and a depth of field of 3 to 100 mm, with clear images and a certain magnification effect, and can detect microscopic gastric cancer and polyps less than half a centimeter in diameter. Gastrointestinal endoscopy has been carried out in China for 40 years and has accumulated rich experimental experience in polypectomy, foreign body removal and esophageal varices ligation. Contraindications to gastroscopy For those who refuse the examination, or those who are nervous and cannot control themselves, most of them can be accepted if the necessity of the examination and the situation during the examination are fully explained before the operation. Those with cardiac arrhythmia and hypertension can be controlled by medication first, and if necessary, cardiac monitoring. Psychiatric patients who can cooperate smoothly can also be made. Absolutely contraindicated are (1) serious heart disease, such as severe arrhythmia, myocardial infarction in the active phase, severe heart failure (2) serious lung disease, such as asthma, respiratory failure can not lie down (3) mental disorders can not cooperate (4) the acute phase of esophageal, gastric and duodenal perforation (5) acute severe pharyngeal disease can not be inserted (6) the acute phase of corrosive esophageal injury With the above brief introduction (5) Acute critical laryngeal diseases that cannot be inserted Still not very clear? Absolute fasting, no water can not eat anything. The electrocardiogram before the examination is to exclude the possibility of arrhythmia, myocardial infarction, which is now significantly younger, 20 years old is possible, one of the manifestations is epigastric pain. During gastroscopy, you must breathe in through your nose and out through your mouth, and you must keep breathing continuously, otherwise it will be very uncomfortable. Do not eat and drink immediately after the examination, as it may cause choking or accidental aspiration. The discomfort of the examination may be due to the patient’s nervousness and anxiety and poor cooperation, or it can be due to the doctor’s unskilled operation and too many unnecessary movements, so doctors should strictly grasp the indications and try to improve their business skills and shorten the operation time while asking the patients.
