ENDOSCOPIC ULTRASOUND/FINE NEEDLE ASPIRATION (EUS/FNA)
Endoscopic ultrasound is a relatively new diagnostic tool that combines standard endoscopy with ultrasound technology to image and biopsy various digestive organs. It is often used to evaluate the pancreas in greater detail, stage cancers, study bile duct abnormalities, evaluate muscles of the lower rectum and anal canal, and identify submucosal lesions.
How to prepare for your EUS procedure?
The GI tract must be empty in order to see inside using the scope. This usually requires the patient to be fasting at least 6-8 hours prior to the procedure.
Patients should tell their doctor about all health conditions they have—especially heart and lung problems, diabetes, and allergies— and all medications they are taking. Patients may be asked to temporarily stop taking medications that affect blood clotting or interact with sedatives, which are often given during EUS.
Driving is not permitted for 12 to 24 hours after procedure due to sedative use. Patients must have someone to drive them home after procedure. Patients can generally eat and drink immediately after procedure.
Patients who develop any of these rare side effects should contact their doctor immediately:
- Swallowing difficulties
- Throat, chest, and abdominal pain that worsens
- Bloody or very dark stool
