Whole gastrointestinal tract radiography

Whole gastrointestinal tract radiography refers to a method of performing radiographic examinations on the digestive system, including examinations of tissues and organs such as the esophagus, stomach, small intestine, and large intestine. We must first perform a chest and abdominal X-ray to understand whether the patient has any heart or lung disease or any metastatic tumors. When conducting this type of examination, you must be aware of some precautions and avoid taking any medications that may affect radiography in the three days before the examination.

Whole gastrointestinal tract radiography

1. Perform chest and abdominal fluoroscopy first. Find out whether there are any lesions in the heart and lungs, metastatic tumors, or diseases such as lung cancer. Peritoneal fluoroscopy is performed to check for high-density shadows that are not X-ray transparent and for contraindications such as obstruction or perforation.

2. Look at the esophagus at a 45-degree right anterior angle.

3. Look at it again 45 degrees to the left front. Double oblique position is used to observe the passage of barium through the esophagus from different angles, and peristalsis can be observed in the supine position when necessary.

4. Lie down on the bed and turn 1-2 circles from right to left (quickly), then lie on your back and look at the stomach. Make sure the barium is evenly coated on the gastric mucosa as much as possible to prepare for mucosal observation.

5. Supine position, observe the posterior wall of the gastric body and antrum from the right anterior oblique

6. Supine left anterior oblique position] Observe the filling phase of the gastric fundus and gastric body and antrum and the filling phase of the duodenum

7. Look for lesions on the anterior wall of the stomach in the prone position.

8. Semi-recumbent right anterior oblique

9. Observe the filling phase and peristalsis of the gastric body and antrum in the semi-recumbent left anterior oblique position

10. Drink barium in a standing position to see the fullness of the stomach

11. Standing Compression Image

12. Finally, stand up and scan from the esophagus to the stomach again

Things to note during the examination: Ⅰ. Stop taking drugs that are not X-ray-painted or affect gastrointestinal function 3 days before the examination. Such as bismuth subcarbonate and calcium gluconate. Ⅱ Eat less indigestible food and fast after dinner one day before the examination. Ⅲ Patients with gastric retention should undergo gastric lavage the night before examination. The purpose is to remove gastric contents and facilitate barium meal examination. Ⅳ Perform a full digestive tract barium meal examination. Take 100 grams of barium sulfate powder mixed with warm water before the examination. Ⅴ Swallowed barium will not be absorbed, is harmless to the body, and will be excreted from the body with the stool. You will have white stool 1-2 days after the barium meal examination, so don't be nervous. Ⅵ Pregnant women within three months are prohibited from undergoing this examination. Ⅶ Barium meal examination is generally not performed during gastrointestinal bleeding and needs to be performed after the bleeding stops. .
