Endoscopic Ultrasound (EUS) is a minimally invasive procedure that allows our specialists at Tulsa Gastrointestinal Consultants (TGiC) to obtain high-resolution images of your digestive tract and surrounding organs. This advanced technique combines endoscopy and ultrasound technology to help diagnose and evaluate conditions affecting the esophagus, stomach, pancreas, liver, and bile ducts.

If your doctor has recommended an EUS procedure in Tulsa, we are here to guide you every step of the way.

What Is an Endoscopic Ultrasound (EUS)?

An Endoscopic Ultrasound (EUS) is a specialized procedure that involves inserting a thin, flexible tube with an ultrasound probe into the digestive tract. Unlike traditional imaging tests, EUS provides detailed images of the gastrointestinal (GI) tract, nearby organs, and lymph nodes, making it highly effective in detecting abnormalities, such as tumors, cysts, and inflammation.

Why Is Endoscopic Ultrasound Performed?

EUS is used for both diagnostic and therapeutic purposes. Your doctor may recommend the procedure to:

• Detect and stage cancers of the esophagus, stomach, pancreas, and rectum
• Evaluate pancreatic cysts, tumors, or inflammation
• Assess chronic abdominal pain and unexplained weight loss
• Diagnose bile duct and gallbladder diseases
• Examine the layers of the GI tract for conditions like Barrett’s esophagus
• Guide fine-needle aspiration (FNA) biopsies for accurate tissue sampling

By providing detailed imaging and precise guidance for biopsies, EUS helps avoid more invasive surgical procedures while ensuring accurate diagnoses.

How to Prepare for an Endoscopic

Proper preparation ensures a smooth and effective procedure. Here’s what you need to do:

• Fasting: Do not eat or drink anything for at least 6 to 8 hours before your appointment.
• Medications: Inform your doctor about all medications you take, especially blood thinners, diabetes medications, or heart medications. Adjustments may be needed.
• Allergies & Health Conditions: Let your doctor know if you have allergies to anesthesia or a history of heart/lung problems.
• Transportation: Since sedation is used, you will need a responsible adult to drive you home after the procedure.

Your healthcare provider will give you specific instructions based on your medical history to ensure a safe and successful procedure.

What to Expect During the EUS Procedure

1. Sedation & Comfort: You will receive mild to moderate sedation to help you relax and prevent discomfort.
2. Insertion of the Endoscope: A thin, flexible tube (endoscope) with an ultrasound probe will be gently inserted through your mouth or rectum, depending on the area being examined.
3. Imaging & Biopsy (If Needed): The ultrasound probe sends high-frequency sound waves to create detailed images of internal structures. If necessary, a fine-needle aspiration (FNA) biopsy may be performed to collect tissue samples.
4. Completion: The procedure typically takes 30-60 minutes, and you will be monitored as the sedation wears off.

Most patients experience little to no discomfort, and recovery is quick.

What to Expect After the Procedure

•  Recovery: You will rest in a recovery area for about 30-60 minutes until the sedation effects wear off.
• Temporary Side Effects: You may experience mild throat discomfort, bloating, or drowsiness, which usually resolves within a few hours.
• Activity Restrictions: Avoid driving, operating machinery, or making important decisions for 24 hours due to sedation effects.
• Follow-Up: Your doctor will discuss preliminary findings and schedule a follow-up if a biopsy was taken.

Most patients resume normal activities by the next day with minimal discomfort.

Is Endoscopic Ultrasound Safe?

Yes, EUS is a safe and well-tolerated procedure when performed by experienced specialists. While complications are rare, possible risks include:

• Bleeding (especially if a biopsy is taken)
• Infection (rare but possible)
• Perforation (tear in the GI tract) (extremely rare)
• Allergic reaction to sedation

At TGiC, our expert gastroenterologists follow the highest safety standards to minimize risks and ensure the best possible care.

1. Is EUS painful?

No, EUS is a minimally invasive procedure. You will be sedated to ensure comfort, and most patients feel no pain during the procedure.

2. How long does an EUS take?

The procedure usually takes 30 to 60 minutes, but you should plan to spend a few hours at the facility for preparation and recovery.

3. Can I eat after the procedure?

You can usually resume eating once the sedation wears off. Start with light foods and drink plenty of fluids. Follow any dietary recommendations from your doctor.

4. When will I get my results?

Preliminary results may be available immediately. If a biopsy was taken, final results typically take a few days and will be discussed in a follow-up visit.

5. Is EUS better than a CT scan or MRI?

EUS provides higher-resolution images and allows for real-time biopsy sampling, making it more effective for detecting certain GI conditions and tumors than CT scans or MRIs alone.
