什么是上部gi和小肠系列？

When you swallow a piece of food, it travels through your:

  • 嘴
  • 食管
  • stomach
  • small intestine

然而，有时，食物不会通过消化系统妥善行驶。这可能导致恶心，胃部不适和腹痛。

如果您有这些或其他症状，您的医生可能会推荐上胃肠道（GI）和小肠系列。这种无痛的成像测试允许您的医生可视化这些区域并追踪问题。

Your doctor uses the upper GI and small bowel test to detect abnormalities in the esophagus, stomach, and small intestine. The test can pinpoint conditions ranging from slow intestinal movement to swallowing disorders and scarring in your digestive tract.

The upper GI and small bowel series mimic the flow of food from your mouth to your small intestine. You’ll be advised to stop eating for a certain time period before the test. You also should refrain from taking certain medications that may affect the test’s outcome, such as antacids, narcotics, or anticholinergics.

当你到达时，你会消耗一杯厚厚的一致性，类似于奶昔。饮料包含钡，一种在服用X射线时会出现的物质。如果您认为您可能对放射学造影材料过敏，请务必告诉您的医生。

Your imaging technologist will take several images of you during the process. The images will show the barium moving through your digestive system.

The time the test takes varies between 20 minutes to four hours. During this time, X-rays may be taken in sitting or standing positions to obtain different views of your body. You’ll be instructed to hold your breath and remain as still as possible while the X-rays are taken.

After the test is over, drink plenty of fluids and foods high in fiber. This helps to keep the barium moving through your system. The barium can cause your stool to be lighter in color for 24 to 72 hours after the procedure. Unless your doctor directs you otherwise, you can return to your normal diet following the test.

Because the test involves X-ray imaging, you’re exposed to a small degree of radioactive material. However, the risk for adverse effects due to radiation exposure is minimal.

If you’ve been experiencing stomach pains or difficulty with digestion, you may have trouble passing the barium through your digestive system. Tell your doctor if you haven’t passed light-colored stools within two to three days after the procedure. This can indicate you haven’t passed the barium.

It may take your doctor several days to review and evaluate the results of your upper GI and small bowel test. Your doctor will examine the scans to determine how well and how fast the barium traveled through your digestive system.

食管中的异常可以精确定位：

  • achalasia, which is a disorder affecting esophagus’ ability to move food into the stomach
  • 憩室，它是食道中的异常袋或囊
  • 食道癌
  • a narrowing of the esophagus
  • a hiatal hernia, which occurs when a part of the stomach sticks through an opening in the diaphragm and juts up into the chest
  • 溃疡

胃中的异常可能表明：

  • 胃癌
  • 溃疡
  • 胃衬里的炎症
  • 息肉
  • pyloric stenosis, which is a condition in which the stomach’s opening to the small intestine, or the pylorus, becomes narrowed

Abnormalities in the small intestine can indicate:

  • poor absorption
  • inflammation of the small intestine
  • 一个肿瘤
  • 溃疡
