Discover the Importance of Gastric Emptying Study: A Comprehensive Guide
Gastric emptying study (GES) is a medical test that measures how quickly your stomach empties its contents into the small intestine. It can help diagnose and manage conditions that affect the stomachs ability to function properly.
What is a Gastric Emptying Study?
GES is a non-invasive procedure that typically involves consuming a meal containing a radioactive tracer. The tracer allows doctors to track the movement of food from the stomach into the small intestine using a gamma camera.
Why is a Gastric Emptying Study Performed?
GES is commonly performed to diagnose and evaluate conditions such as:
- Gastroparesis (delayed stomach emptying)
- Dumping syndrome (rapid stomach emptying)
- Diabetic gastroparesis
- Pyloric stenosis (narrowing of the stomach outlet)
How is a Gastric Emptying Study Performed?
Before the procedure, you will be asked to fast for several hours. You will then consume a meal containing the radioactive tracer, typically an egg sandwich or oatmeal. For the next 2-4 hours, you will lie under the gamma camera, which will take images of your stomach and track the movement of the tracer.
Gastric Emptying Study CPT
The Current Procedural Terminology (CPT) code for a gastric emptying study is 76854: Gastric emptying study, radioisotope.
Interpretation of Results
The results of the GES are typically interpreted by a nuclear medicine physician. They will calculate the gastric emptying half-time (T½), which is the time it takes for half of the meal to leave the stomach. Normal T½ values vary depending on the type of meal consumed, but generally range from 60-120 minutes for a solid meal and 30-60 minutes for a liquid meal.

Conditions Associated with Abnormal Gastric Emptying
Abnormal gastric emptying can be caused by a variety of conditions, including:
- Diabetes
- Autoimmune diseases
- Medications (e.g., opioids, antidepressants)
- Surgery
- Neuropathy
Symptoms of Abnormal Gastric Emptying
People with abnormal gastric emptying may experience symptoms such as:
- Nausea and vomiting
- Abdominal pain and bloating
- Early satiety
- Weight loss or gain
- Heartburn and acid reflux
Treatment of Abnormal Gastric Emptying
The treatment for abnormal gastric emptying depends on the underlying cause. Treatment options may include:
- Dietary modifications
- Medications
- Surgery
Case Study: Gastroparesis
Brenda, a 35-year-old woman with type 1 diabetes, has been experiencing severe nausea and vomiting for the past few months. Her doctor suspects gastroparesis and orders a GES. The results show a T½ of 240 minutes, confirming the diagnosis. Brenda is started on a prokinetic medication to improve her gastric motility.
Case Study: Dumping Syndrome
John, a 40-year-old man, underwent a gastric bypass surgery for weight loss. Since then, he has been experiencing episodes of severe diarrhea and abdominal pain after meals. His doctor performs a GES and finds a T½ of 15 minutes, indicating dumping syndrome. John is advised to make dietary changes, such as eating smaller, more frequent meals and avoiding sugary drinks.
Conclusion
Gastric emptying study is a valuable tool for diagnosing and managing conditions that affect the stomachs ability to empty properly. By understanding the CPT code, interpretation of results, and treatment options, healthcare professionals can provide optimal care for patients with gastric emptying disorders.
