What examination should be done before gastroscopy

summary

The results of clinical statistics show that there is a significant positive correlation between the occurrence of this disease and age. The older the age is, the worse the "resistance" of gastric mucosal function is. It is easy to be affected by external adverse factors and cause damage. Then some patients put forward to do what examination before gastroscopy.

What examination should be done before gastroscopy

Examination 1: gastroscopy in the morning: no food or drink and no smoking after 8 pm the day before. The day before, I had a little digestible food for dinner. Because even if the patient drinks a small amount of water, it can also change the color of gastric mucosa, such as the natural color lesions of significant atrophic gastritis. After drinking water, the gastric mucosa can become red, making the diagnosis wrong.

Examination 2: gastroscopy in the afternoon: the patient can drink some sugar water before 8 a.m. on the same day, but can't eat other things, and don't eat at noon. For patients with pylorus obstruction, gastric lavage must be carried out the night before the examination, and the contents of the stomach must be thoroughly cleaned until the reflux fluid is clear.

Examination 3: detection of Helicobacter pylori. One more piece of living tissue can be taken for rapid urease examination during endoscopy to increase the reliability of diagnosis of Helicobacter pylori infection. Helicobacter pylori antibody detection is to use colloidal gold technology to qualitatively detect anti Helicobacter pylori antibodies in human serum, plasma or whole blood. When the patient's sample contains the specific antibody of gastric Helicobacter pylori, it forms antigen antibody antigen colloidal gold particle complex with the antigen on the detection line (t line), and shows the red line. It is one of the ideal methods to test Helicobacter pylori by breath test with breath detector because of its simple process and no adverse reaction. And the sensitivity of the test results is above 95xff05, which is the gold standard of HP detection in the medical community.

matters needing attention

It is suggested that we should pay attention to: through the investigation of 200 patients with chronic gastritis, it is found that the recurrence rate of non-smoking patients with gastritis is only 38.3%, but the recurrence rate of smoking patients with gastritis is as high as 61.7%. Therefore, patients with chronic gastritis should quit smoking in order to cure gastritis as soon as possible.
