Endoscopic Ultrasound (EUS) is a minimally invasive procedure that combines
the technologies of endoscopy and ultrasound to provide detailed images
of your digestive tract and nearby organs. During the procedure, a thin,
flexible tube called an endoscope is gently inserted through your mouth
into your digestive tract. Equipped with a small ultrasound device at
its tip, the endoscope emits sound waves that produce clear, precise images
of both the digestive and lung systems, allowing for close examination.
Why do We Use EUS?
EUS is useful for diagnosing and evaluating conditions that other tests
might miss. It helps with:
Finding and staging digestive system cancers, like esophageal, stomach,
pancreatic and rectal cancers.
Checking for chronic pancreatitis or other issues with the pancreas.
Looking for bile duct stones and other problems in the bile duct.
Examining unusual growths in the gastrointestinal tract.
Guiding fine-needle aspiration (FNA) to get tissue samples for biopsy.
EUS Procedure Overview
Sedation: Medications will be administered through an IV to help you relax or sedate
you. Sometimes, a numbing medication is used for the throat. A bite block
is placed to protect your teeth, and dentures must be removed. You will
likely lie on your left side during the procedure.
Endoscopic Insertion: The doctor gently inserts the endoscope through your mouth and guides
it into your digestive tract. Depending on the area to be examined, the
endoscope may also be inserted through the anus.
Imaging: The ultrasound device at the end of the scope sends out sound waves, creating
detailed images of your tissues and organs. This allows the doctor to
closely examine the walls of your digestive tract and nearby structures,
such as the pancreas, liver, and lymph nodes.
Fine-Needle Aspiration (Optional): If necessary, the doctor can pass a thin needle through the endoscope
to take a biopsy (tissue sample) from any abnormal areas seen during the
ultrasound.
After the Procedure:
Recovery: You will stay in the recovery area until the sedation wears off. You might
feel groggy, so it’s best to rest for the day. You may have a sore
throat or feel bloated.
Diet and Activity: Follow your doctor’s advice. Start with fluids and light meals.
Avoid heavy lifting and strenuous activities for 48 hours.
Possible Complications
EUS is generally safe, but like any medical procedure, there are some risks.
Potential complications include:
Infection
Bleeding
Pancreatitis (inflammation of the pancreas)
Perforation (a tear in the gastrointestinal tract)
Allergic reaction to sedatives or contrast dye
Your doctor will explain these risks in detail before the procedure and
discuss any specific concerns you may have.
When to Call Your Doctor
After the procedure, contact your doctor if you experience:
Fever.
Severe or constant stomach pain.
Neck or chest pain.
Severe nausea or vomiting.
Vomiting blood.
Black or very dark-colored stool.
These could be signs of a complication that needs immediate attention.
General Preparation Instructions for Gastrointestinal Procedures
Each gastrointestinal procedure requires specific preparations to ensure
your safety and the success of the treatment. Here are some general guidelines:
Fasting: Avoid food and drinks, including water, for several hours, or more as
instructed by your healthcare provider.
Medications: You may need to adjust or pause certain medications. Follow the specific
directions given by your doctor.
Bowel Prep: Some procedures require clearing the intestines using either a liquid
solution or pills containing laxatives. Procedures like colonoscopy, flexible
sigmoidoscopy, and PillCam capsule endoscopy typically require this type
of preparation.
Please consult your doctor for detailed preparation instructions tailored
to your health needs and the specific procedure.
