Diagnose chronic pancreatitis & esophageal, stomach & rectal cancers.

This minimally invasive procedure combines endoscopy with ultrasound. It can be used to diagnose chronic pancreatitis and esophageal, stomach and rectal cancers. It can also be used to treat abdominal pain associated with chronic pancreatitis and pancreatic cancer. An ultrasound transducer is placed at the end of an endoscope and advanced into the intestine. A transducer is a device that receives a signal in the form of one type of energy and converts it to another form.The ultrasound transducer produces a high-resolution image of the gastrointestinal lining and other structures located beyond the gastrointestinal wall.

Complications such as perforation are rare. The patient should not eat or drink anything for at least 6 hours prior to the procedure.

What to Expect

Preparation for the Procedure
  1. I'm dizzy or have a headache, what should I do?

    Dizziness and headache could be signs of low blood sugar. Drinking a regular carbonated beverage (not diet) or apple juice may alleviate these symptoms.

  2. What is the best "clear" liquid to take?

    Gatorade, which comes in many flavors, is an excellent choice as it contains electrolytes such as potassium. Avoid RED/BLUE liquids. We also recommend beef and chicken bouillon made from cubes (not broth).

  3. Why avoid red/blue liquids?

    The color can persist in the colon and make an accurate diagnosis more difficult.

  4. Can I drink alcoholic beverages?

    We strongly suggest you do not drink any alcoholic beverages prior to your procedure since they can cause dehydration and some wines may thin your blood.

  5. Can I chew gum or suck candy?

    Yes, but nothing with soft centers or red color. No candy is allowed 4 hours prior to your procedure.

  6. I have been instructed not to take anti-inflammatories or blood thinners several days before the procedure. What can I take for headaches and pain relief?

    You may take Tylenol as directed.

Day of Procedure Questions
  1. What should I wear?

    Loose comfortable clothing is recommended. You can wear make up but we advise patients not to wear jewelry. If you wear contacts please bring your case and solution so that you can remove them prior to your procedure.

  2. Can I drive myself home after the procedure?

    No, since sedatives are used, another driver is needed. This driver MUST stay during the procedure or the procedure will not be performed. This is for your personal safety. You may bring more than one person with you, but only one person can be with you in recovery due to space limitations.

  3. What if I am still passing stool the morning of my test?

    Take a tap water enema until you run clear. If this does not work, call the office.

  4. One of the medications I was instructed to take the morning of my procedure is red. Can I take it?

    Medication for blood pressure, heart conditions, and seizure should be taken the morning of your exam regardless of the color. Light blue and light pink medications are also fine for you to take.

  5. Can I brush my teeth?


  6. Can I wear my dentures?

    Yes, you may wear your dentures to the Endoscopy suite. However, you may be asked to remove them prior to the procedure.

  7. Why do I have to be there an hour before the time procedure is scheduled? What if I am running late?

    We ask patients to arrive early so that we can do a pre-procedure assessment and start the IV. Please call if you are running more than 15 minutes late, so that we can work together to adjust the schedule so that we can accommodate this delay.

After the Procedure Questions
  1. I am still dizzy and lightheaded after my procedure, why?

    You may have residual anesthesia in your system, additional rest is recommended.

  2. May I go back to work after my procedure?

    No, please remain home the day of your procedure, due to the sedatives you may not think clearly for several hours. DO NOT DRIVE. You can return to work the day after unless your physician specifically tells you otherwise.

  3. How do I get my results?

    Results are given by the doctor to you in the recovery room. You may or may not remember talking to the doctor so your results will also be in your discharge instructions. Pathology may take up to 2 weeks to get results.
