Is It Dangerous To Do Gastroscope?

Electronic gastroscopy is more advanced than fibrous gastroscopy in terms of technical means.

Fibrous endoscopes have been used to diagnose diseases since the 1950s. So far, there are many fiber endoscopes for examining the digestive tract, such as fiber esophagoscopy, fiber gastroscopy, fiber duodenoscope, fiber colonoscopy, fiber colonoscopy and fiber choledochoscopy.

This kind of fiber endoscope is thin and soft and easy to bend, the patient's pain is less, the doctor can directly see some conditions of the examined organ, than X-ray barium meal examination effect is better. It can find the lesion, what is the nature of the lesion, but also can take a small specimen in the lesion site, pathological examination, under the microscope to see what the cell change is like, more helpful for diagnosis.

In recent years, there are electronic gastroscopy, it can reflect the examination situation on the screen, the surgeon and more people can find the lesions through the screen, but also video, as information for future reference.

General fiber gastroscope, duodenoscope working length 70 ~ 140 cm, there are a variety of models, each type of length is also different. It extends from the opening of the esophagus to the duodenum. These parts of the disease such as inflammation, erosion, ulcer, bleeding, esophageal varices, hemangioma, tumor (benign or malignant) mucosal atrophy, gastrointestinal diverticulum, wall elasticity, stomach stomach stomach stomach stomach stomach stomach stomach gastric gastric pylorus closure is normal, there is no duodenal fluid from the pylorus reflux to the stomach. The bleeding patients can not only do emergency gastroscopy to check the bleeding location and nature, but also can give gastroscopy medicine to stop the bleeding.

In order to prevent hepatitis transmission, patients with hepatitis and those without hepatitis should be separated by gastroscopy, and liver function and surface antigen of hepatitis B should be examined before gastroscopy.

In order to see the mucous membrane of the digestive tract clearly, the area to be examined must be clean, i.e. free of food and blood clots. If you have a gastroscopy in the morning, do not eat or drink, and do not smoke after 8 p.m. the day before. Eat light, digestible food for dinner the night before. Even if the patient drinks a small amount of water, the color of the gastric mucosa can be changed. For example, in the natural lesions of significant atrophic gastritis, the gastric mucosa can turn red after drinking water, which makes the diagnosis wrong. If a gastroscope is performed in the afternoon, the patient can drink some sugar water before 8 a.m. that day, but can not eat other things, and do not eat food at noon. For patients with pyloric obstruction. Gastric lavage must be performed the night before the examination, and the contents of the stomach must be thoroughly washed until the reflux fluid is clear. Before the gastric tube was withdrawn after gastric lavage, the patient was placed in a supine position with head low and foot high so that the residual fluid in the stomach could be completely discharged. Gastric lavage should not be performed on the same day because it can change the color of gastric mucosa. If a barium meal examination has been done, the barium meal may be attached to the gastrointestinal mucosa, especially the ulcerative lesion site, which makes the diagnosis of fibroscopy difficult. Therefore, it is necessary to do the gastroscopy 3 days after the barium meal examination.
