What is Endoscopic Ultrasound (EUS)?
Endoscopic Ultrasound (EUS) is a diagnostic technique that uses a flexible endoscope with a built-in ultrasound probe. The device is inserted through the mouth into the digestive tract, where it generates detailed images of the esophagus, stomach, pancreas, bile ducts, and nearby lymph nodes. EUS is highly valued for evaluating tumors, staging cancers, and guiding fine-needle aspiration biopsies. It provides more precise imaging than standard ultrasound or CT scans because the probe is positioned close to the organs of interest.
This procedure helps to:
- Evaluate pancreatic and bile duct abnormalities.
- Stage cancers of the digestive tract.
- Assess submucosal lesions or growths.
- Guide biopsies of tumors or lymph nodes.
- Provide high-resolution imaging not available with other tests.
What to expect after Endoscopic Ultrasound?
EUS is performed under sedation. Patients may experience a sore throat or bloating afterward, but recovery is usually fast. If a biopsy is taken, some mild discomfort may persist for a short time.
- Sedation ensures comfort during the procedure.
- Mild sore throat or bloating afterward.
- Normal activities may resume later the same day.
- Results discussed with the physician once available.
- Slight dietary restrictions if biopsies are performed.
