The current situation of gastric cancer in China is that the incidence rate is high, but the early diagnosis rate is low and the survival prognosis is poor.
The incidence of gastric cancer remains high, and more and more people around us are suffering from gastric diseases, so gastroscopy has become familiar to the general public. However, do you really know about gastroscopy? The so-called gastroscope, in short, is a fiber optic hose with a camera. During the examination, through the mouth or nose, the fiber hose into the digestive tract, the doctor can observe the esophagus, stomach, duodenum surface mucosa, while observing whether there are ulcers, abnormal bulging masses, varicose blood vessels. What do I need to pay attention to during gastroscopy? To perform gastroscopy, in order to clearly see the mucosa of the digestive tract, the examined area must be clean, i.e., no food and no blood clots remain. If the gastroscopy is done in the morning, no food and drink, no smoking, and easy-to-digest food with little residue for dinner the day before the examination after 8:00 pm. This is because even if the patient drinks a small amount of water, the gastric mucosa color can change, such as in the native lesions of significant atrophic gastritis, the gastric mucosa can change to red after drinking water, making the diagnosis wrong. If gastroscopy is done in the afternoon, the patient may be allowed to drink some sugar water before 8:00 am that day, but not to eat anything else and not to eat anything at noon. In the case of a patient with pyloric obstruction, gastric lavage must be performed the night before the examination to thoroughly wash out the stomach contents until the refluxed fluid is clear. Before the gastric tube is withdrawn after lavage, the patient is placed in a supine position with head down and feet up to allow complete drainage of residual fluid from the stomach. Gastric lavage cannot be performed on the same day because it can change the color of the gastric mucosa. If barium meal examination has been done, this barium meal barium may be attached to the gastrointestinal mucosa, especially the site of ulcerative lesions, making the diagnosis of fiber gastroscopy difficult, so it must be done 3 days after the barium meal examination and then gastroscopy. Second, who needs to do gastroscopy? If you have the following conditions, it is recommended to go to a regular hospital for gastroscopy: frequent difficulty in swallowing, upper abdominal pain, non-stop burping, acid reflux, obvious feeling of fullness; unexplained vomiting of blood, black stools, unexplained abdominal pain (repeated pain and location is not clear), combined with medical history, gastroscopy is recommended; cirrhosis and other diseases need to improve the esophagus, gastric fundus and other complications assessment patients; Patients who need regular follow-up after surgery for upper gastrointestinal tract tumors such as gastric cancer and esophageal cancer; patients with high risk of gastric cancer: patients whose immediate family members have had gastric cancer and whose previous examinations showed high risk factors need regular gastroscopy for timely detection of early gastric cancer; C. How to look at the gastroscopy report? Generally, you can get the gastroscopy report soon after gastroscopy, but you need to pay attention to whether tissue biopsy is performed or not. Whether biopsy is performed or not is judged by the operating doctor with clinical experience, and generally biopsy is taken for suspicious tissues and tissue examination is performed to judge the nature. If no biopsy is performed, regardless of the degree described in the report, it is a different manifestation of inflammation, and the doctor will decide whether to treat and the treatment plan by taking into account the symptoms, whether to combine H. pylori infection and the degree, so there is no need to worry too much. Postoperative care: After the operation, tell the patient to wait for about 30 minutes after the anesthetic before eating if there is no biopsy, and to eat a warm and cool liquid diet after 2 hours if there is a biopsy, in order to reduce the friction on the traumatic surface of the gastric mucosa. After the operation, there may be throat discomfort or pain, or hoarseness, the patient will improve in a short time, no need to be nervous, use light saline gargle or throat tablets. Observe whether there is active bleeding, such as vomiting blood, blood in stool, abdominal pain, abdominal distension, and changes in important vital signs, such as heart rate and blood pressure, etc. If abnormalities are found, take appropriate treatment immediately. After gastroscopy, you may feel vomiting, so do not get out of bed immediately to avoid fainting.
Since gastroscopy requires fasting, the stomach is empty when doing the examination, so the speculum has to inflate the stomach after entering it. This pain usually disappears in one to two hours, but if the pain lasts for four hours or more, it needs to be treated by a doctor. In short, the body should pay more attention to itself, do not be overly afraid of gastroscopy, worry about discomfort, but also do not take changes in their own physical condition lightly, scientific and rational view of gastroscopy and stomach diseases, the correct perception of the examination and disease.
