Can gastroscopy be performed for gastric bleeding?

Gastroscopy is an important means of checking stomach health. Through gastroscopy, the doctor can clearly see the situation inside the stomach, and can also see whether the esophagus, duodenum and other parts are healthy. As a commonly used examination method, gastroscopy can also be used as a method to examine gastric bleeding. However, some patients with gastric bleeding do not know much about gastroscopy. Can gastric bleeding be treated with gastroscopy?

If there is severe bleeding in the stomach, it is usually necessary to find out the cause and a gastroscopy is necessary.

There are many reasons for heavy bleeding. One is the original reasons of the stomach, such as inflammation, ulcers, CA, etc. The other is liver disease. Because the blood vessels of the stomach are converged into the liver blood vessels, the blood return of the liver is difficult when the liver is diseased, and the blood in the stomach is stagnant in the fundus of the stomach and the lower esophagus. Over time, the blood vessels in the stomach and the lower esophagus swell and are prone to rupture and bleeding. The third is other reasons, such as stress bleeding caused by major stimulation.

Preparation before gastroscopy

1. To avoid cross infection, reasonable disinfection measures should be formulated and patients should undergo HBsAg, anti-HCV, anti-HIV and other tests before examination.

2. Do not eat for 6 to 8 hours before the examination. The examination should be performed on an empty stomach. If there is food in the stomach, it will affect the observation. Those who have undergone barium meal examination must wait until the barium is emptied before undergoing gastroscopy; patients with pyloric obstruction should fast for 2 to 3 days and, if necessary, undergo gastric lavage before surgery to remove food accumulated in the stomach.

3. Oral defoaming agents, such as simethicone, can remove surface tension, causing the foam attached to the mucous membrane to burst and disappear, making the field of vision clearer.

4. Pharyngeal anesthesia aims to reduce pharyngeal reaction, facilitate endoscope insertion and reduce patient pain. Patients with a history of allergy to anesthetic drugs may not be given anesthesia. There are two methods: ① Spray method: Use 1% dicaine or 2% lidocaine or other pharyngeal spray anesthesia 15 minutes before the operation, once every 1 to 2 minutes, for a total of 2 to 3 times; ② Oral anesthetic preparations can be swallowed before the operation and checked. This method is simple and time-saving.

5. Sedatives and antispasmodics: Not necessary for general patients. For patients who are nervous, 10 mg of diazepam can be injected intramuscularly or slowly intravenously 15 minutes before the examination to eliminate tension. Antispasmodics such as scopolamine or atropine can reduce gastric motility and spasm, making it easier to observe, but attention should be paid to their side effects.

Before doing a gastroscopy, you also need to pay attention to not wearing tight clothes. If you have to wear tight clothing, the belt and buttons need to be unbuttoned to avoid unnecessary trouble during the gastroscopy. Of course, if you wear dentures, you will need to take them out before the examination. If you feel uncomfortable at the innermost part, you can bite the dental pad.
