Gastroesophageal Reflux
Gastroesophageal Reflux
A condition where stomach acid flows back up into the esophagus, causing irritation and discomfort.
Esophagitis
Esophagitis
Inflammation of the esophagus caused by prolonged exposure to stomach acid.
Dysphagia
Dysphagia
Difficulty swallowing, often caused by inflammation or narrowing of the esophagus.

Study Notes
Gastroesophageal Reflux Complications
- Esophagitis and dysphagia (difficulty swallowing) in adults.
- Failure to thrive and aspiration pneumonia in infants.
Diagnostic Method: Gastroesophageal Scintigraphy
- Sensitive method for detecting reflux.
Patient Preparation
- Fast for several hours before imaging.
- Adults: 150 mL 99Tc-sulfur colloid mixed with orange juice and 150 mL dilute hydrochloric acid orally.
- Infants: Mixed with infant formula via a nasogastric tube or baby bottle.
- Entire tracer volume must be consumed.
Imaging
- Patient Positioning: Supine position under the scintillation camera with the stomach positioned low to include the esophagus and lung fields.
- Image Acquisition: Serial images obtained with varying abdominal pressure using an abdominal binder.
- Delayed Imaging: Delayed lung field images up to 24 hours after tracer administration to detect intermittent reflux.
Image Findings
- Esophageal Reflux Confirmation: Presence of radioactivity in the esophagus or lungs.
- Normal Study Result: No esophageal reflux observed.
Technical Considerations
- Patient Side Effect: The patient may experience emesis (vomiting).
- Technologist Preparation: The technologist should take steps to minimize possible radioactive contamination before the procedure begins.
