An UGI includes everything from the mouth all the way to the small bowel just beyond the Ligament of Treitz. Therefore, when we do an UGI examination, we thoroughly examine the esophagus, we look for a hiatal hernia and esophageal reflux. Any time we would see anything in the esophagus that would require documentation, spot filming and/or overhead filming would be obtained, just as it would if we saw something in the stomach or duodenal bulb.
So, in most instances, the combination of ordering an esophagram with an upper GI is redundant because an esophagram is part of an upper GI. It is not redundant to order an esophagram (aka Barium Swallow) by itself if, for instance, dysphagia is the only symptom and there are no other upper gastrointestinal complaints (the insurance companies will pay for an esophagram done by itself).
I would urge you to keep this in mind when ordering barium studies of the
upper
gastrointestinal tract. If you order an esophagram/upper GI combination your
patient may have
to pay more out of their pocket, as the insurance companies normally would
pay for only one of
the procedures and that is the esophagram, as it is the lowest reimbursement.
Esophagram (Barium Swallow)
Indication - The esophagram test is ordered to assess symptoms of painful or difficult swallowing, bloodstained vomit, abdominal pain and weight loss. Our radiologist is able to detect narrowing or irritation of the esophagus, blockages, hiatal hernia, abnormally enlarged veins that may cause bleeding in the esophagus, ulcers, polyps or tumor.
Description - The esophagram or barium swallow is a test whereby a patient is instructed to drink a barium sulfate compound that enables the radiologist to study the function and appearance of the esophagus and assess the swallowing process.
Procedure - For
this test the patient is given a cup of barium sulfate to drink while the
radiologist watches and evaluates the swallowing process with fluoroscopy (an
x-ray unit
combined with a TV monitor). As the barium coats the lining of the esophagus
x-rays are taken
to track the pathway to the stomach. The patient is placed in various positions
throughout the
exam so that structures are optimally demonstrated on the x-rays. The
approximate time for
the examination is 30 minutes.
Upper Gastrointestinal (GI) series
Indication - The upper GI series is indicated for assessing problems such as abdominal swelling, bloating, pain, nausea, and vomiting. It may be used to detect the cause of painful or difficult swallowing.
The radiologist may also find evidence of ulcers, scar tissue, abnormal growths, hiatal hernia, or blockage of the normal food path through the digestive tract.
Description - The upper GI series is a test to diagnose problems
in the esophagus, stomach and duodenum. A barium drink is given to the patient
to swallow to coat the lining of the
esophagus, stomach and duodenum allowing them to show up
clearly on the x-ray images. The upper GI series can
demonstrate a blockage, abnormal growth, ulcer or identify a
problem with organ function.
Procedure - The technologist may take an initial
film of the
abdomen (a scout film) to make sure that the GI tract is
properly prepped for the exam. The procedure is performed on
a table with tilting capabilities so the radiologist is able move
the patient from a standing to a reclined position. The patient
may be given a small cup of effervescent crystals to swallow
that allow gas to be created in the stomach for better imaging.
The patient is then given a cup of barium and instructed to
drink.
The radiologist watches the travel of the barium with
fluoroscopy as it moves down the throat, into the stomach, and
finally into the small bowel. X-rays are taken with the patient in
various positions that best demonstrate the areas of interest.
The approximate time for the exam is 30 to 45 minutes.
