Tests and diagnosis discussion for Gastroparesis:
The diagnosis of gastroparesis is confirmed
through one or more of the following tests:
- Barium x-ray: After fasting for 12 hours, you will drink a
thick liquid called barium, which coats the inside of the stomach,
making it show up on the x-ray. Normally, the stomach will be empty of
all food after 12 hours of fasting. If the x-ray shows food in the
stomach, gastroparesis is likely. If the x-ray shows an empty stomach
but the doctor still suspects that you have delayed emptying, you may
need to repeat the test another day. On any one day, a person with
gastroparesis may digest a meal normally, giving a falsely normal test
result. If you have diabetes, your doctor may have special instructions
about fasting.
- Barium beefsteak meal: You will eat a meal that contains
barium, thus allowing the radiologist to watch your stomach as it
digests the meal. The amount of time it takes for the barium meal to be
digested and leave the stomach gives the doctor an idea of how well the
stomach is working. This test can help detect emptying problems that do
not show up on the liquid barium x-ray. In fact, people who have
diabetes-related gastroparesis often digest fluid normally, so the
barium beefsteak meal can be more useful.
- Radioisotope gastric-emptying scan:You will eat food that
contains a radioisotope, a slightly radioactive substance that will show
up on the scan. The dose of radiation from the radioisotope is small and
not dangerous. After eating, you will lie under a machine that detects
the radioisotope and shows an image of the food in the stomach and how
quickly it leaves the stomach. Gastroparesis is diagnosed if more than
half of the food remains in the stomach after 2 hours.
- Gastric manometry:This test measures electrical and muscular
activity in the stomach. The doctor passes a thin tube down the throat
into the stomach. The tube contains a wire that takes measurements of
the stomach's electrical and muscular activity as it digests liquids and
solid food. The measurements show how the stomach is working and whether
there is any delay in digestion.
- Blood tests:The doctor may also order laboratory tests to
check blood counts and to measure chemical and electrolyte levels.
To rule out causes of gastroparesis other than diabetes, the doctor may
do an upper endoscopy or an ultrasound.
- Upper endoscopy.After giving you a sedative, the doctor
passes a long, thin, tube called an endoscope through the mouth and
gently guides it down the esophagus into the stomach. Through the
endoscope, the doctor can look at the lining of the stomach to check for
any abnormalities.
- Ultrasound.To rule out gallbladder disease or pancreatitis
as a source of the problem, you may have an ultrasound test, which uses
harmless sound waves to outline and define the shape of the gallbladder
and pancreas.
