The Procedure of Gastroscopy

People who have done gastroscopy should have the same experience, that is, they are very uncomfortable. After all, it is a foreign body inserted into the stomach. Next, let me tell you about the whole process of gastroscopy from preparation to completion. Let's learn about it together.

At present, gastroscopy is the most widely used and fastest developed endoscopic examination. Through this examination, the nature, size, location and scope of inflammation, ulcer or tumor of esophagus, stomach and duodenum can be directly observed, and histological or cytological pathological examination can be performed.

Before gastroscopy

Fasting for 8 hours, those with pyloric obstruction should eat liquid within 2-3 days before examination, and gastric lavage should be done one night before examination. If you have done X-ray barium meal examination, you should not do gastroscopy within 3 days.

5-10 minutes before examination, take a 2% lidocaine gel orally for local anesthesia. In addition, hepatitis B and C virus markers need to be detected before the examination, and those who are positive should be examined with a special gastroscope!

During gastroscopy

Generally, take the left lateral position, bend your legs, put a low pillow on your head, relax your neck, and loosen your collar and tie. The mouth will usually give us a curved plate to hold the patient's saliva.

The operator faces the patient, holds the operation department in his left hand, and holds the mirror end in his right hand about 20cm. Under direct vision, he inserts it into the oral cavity, and slowly pushes it down along the dorsal tongue and posterior pharyngeal wall to the level of cricoid cartilage. When the upper mouth of the esophagus is visible, he inserts the gastroscope.

At this time, the patient needs to keep the position of the head still. When the gastroscope is inserted 15cm to the throat, ask the patient to swallow, but do not swallow saliva to avoid choking. Let saliva flow into the curved plate or suck it out with a straw.

After gastroscopy

When withdrawing from the endoscope, try to pump air as much as possible to prevent the patient from bloating. The anesthetic effect of throat will not subside after operation, so try not to swallow saliva to avoid choking cough. 2 hours after operation, you can drink a small amount of water first, and then eat if there is no choking cough.On the same day, the diet should be liquid or semi-liquid. Patients undergoing biopsy should fast water for 4 hours and eat a warm and cool diet. Note that if you have sore throat and foreign body sensation in the throat, you must not cough hard to avoid damaging the throat mucosa. If abdominal pain and bloating occur, massage can be performed to promote exhaust!
