Introduction
The duodenum can be examined via gastroscopy, which effectively determines the presence of abnormalities. It is important to note that after the examination, food should be avoided for two hours before gradually resuming a liquid diet to prevent damage to the gastrointestinal tract. If this examination is needed, it is recommended to visit a正规 hospital and undergo the procedure under the guidance of a qualified physician to ensure accurate results.
Under normal circumstances, the duodenum can be examined via gastroscopy, which effectively determines whether any abnormalities are present. The specific procedure is as follows:
1. Prior to the examination, the patient must fast for 8 hours, maintaining an empty stomach or a state of gastric emptiness.
2. The patient lies on their side, and anesthesia is administered to the pharynx to ensure a pain-free experience during the procedure.
3. The endoscope is inserted through the mouth, passing through the pharynx, esophagus, cardia, and stomach, until the duodenum comes into view.
4. After observation is complete, the endoscope is slowly withdrawn, concluding the procedure.
It should be noted that after the examination, patients should remain fasting for two hours before gradually resuming intake of liquid foods to avoid injury to the gastrointestinal tract. If this examination is required, it is recommended to visit a正规 hospital and undergo the procedure under the guidance of a qualified physician to ensure accurate results.
