Definition

Endoscopic ultrasound is a type of imaging test. It is used to see organs in and near the digestive tract.

How the Test is Performed

Ultrasound is a way to see the inside of the body using high-frequency sound waves. Endoscopic ultrasound does this with a thin, flexible tube device called an endoscope.

  • This tube is passed either through the mouth or through the rectum and into the digestive tract.
  • Sound waves are sent out the end of the tube and bounce off the organs in the body.
  • A computer receives these waves and uses them to create a picture of what is inside.
  • This test does not expose you to harmful radiation.

If a sample or biopsy is needed, a thin needle can be passed through the tube to collect fluid or tissue. This does not hurt.

The test takes 30 to 90 minutes to complete.

How to Prepare for the Test

Your health care provider will tell you what to do. You will be told when to stop drinking and eating before the test.

Give your provider a list of all the medicines you take (prescription and over-the-counter), herbs, and supplements. You will be told when you can take these. Some need to be stopped a week before the test. Ask your provider which medicines you should take on the morning of surgery.

Since you will not be able to drive or return to work on the day of this test, you will need someone to take you home.

How the Test will Feel

Before this test you will get medicine through an IV to help you relax (a sedative). You may fall asleep or not remember the test. Some people feel the test is slightly uncomfortable.

For the first hour after this test, you may feel sleepy and unable to drink or walk. You may have a sore throat. Air or carbon dioxide gas may have been put in your digestive tract during the test to move the tube more easily. This may make you feel bloated, but this feeling will go away.

When you are fully awake, you can be taken home. Rest that day. You may have fluids and light meals.

Why the Test is Performed

You may have this test to:

  • Find the cause of abdominal pain
  • Find the cause of weight loss
  • Diagnose diseases of the pancreas, bile duct, and gallbladder
  • Guide a biopsy of tumors, lymph nodes, and other tissue
  • Look at cysts, tumors, and cancers
  • Look for stones in the bile duct

This test can also stage cancers of the:

  • Esophagus
  • Stomach
  • Pancreas
  • Rectum

Normal Results

The organs will appear normal.

What Abnormal Results Mean

The results depend on what is found during the test. If you DO NOT understand the results, or have questions or concerns, talk to your provider.

Risks

Risks for any sedation are:

  • Reactions to medicine
  • Problems breathing

Complications from this test include:

  • Bleeding
  • A tear in the lining of the digestive tract
  • Infection
  • Pancreatitis

Prepare before seeing a doctor

A simple rural-patient checklist to help you explain symptoms clearly, ask better questions, and avoid unsafe self-treatment.

Safety note: This is not a prescription or diagnosis. For severe symptoms, pregnancy danger signs, children with serious illness, chest pain, breathing difficulty, stroke-like weakness, or major injury, seek urgent care.

Which doctor may help?

Start with a registered doctor or the nearest qualified health center.

What to tell the doctor

  • Write when the problem started and how it changed.
  • Bring old prescriptions, investigation reports, and current medicines.
  • Write allergies, pregnancy status, diabetes, kidney/liver disease, and major past illnesses.
  • Bring one family member if the patient is weak, elderly, confused, or a child.

Questions to ask

  • What is the most likely cause of my symptoms?
  • Which danger signs mean I should go to hospital quickly?
  • Which tests are necessary now, and which can wait?
  • How should I take medicines safely and what side effects should I watch for?
  • When should I come for follow-up?

Tests to discuss

  • Vital signs: temperature, pulse, blood pressure, oxygen saturation
  • Basic physical examination by a clinician
  • CBC, urine test, blood sugar, or imaging only when clinically needed

Avoid these mistakes

  • Do not use antibiotics, steroid tablets/injections, or strong painkillers without proper medical advice.
  • Do not hide pregnancy, kidney disease, ulcer, allergy, or blood thinner use.
  • Do not delay emergency care when danger signs are present.

Medicine safety and first-aid guide

This section is for patient education only. It does not replace a doctor, pharmacist, or emergency care.

Safe first steps

  • Rest, drink safe water, and observe symptoms carefully.
  • Keep a written note of symptoms, duration, temperature, medicines already taken, and allergy history.
  • Seek medical care quickly if symptoms are severe, worsening, or unusual for the patient.

OTC medicine safety

  • For mild pain or fever, ask a registered pharmacist or doctor before using common over-the-counter pain/fever medicines.
  • Do not combine multiple pain medicines without advice, especially if you have kidney disease, liver disease, stomach ulcer, asthma, pregnancy, or take blood thinners.
  • Do not give adult medicines to children unless a qualified clinician advises it.

Avoid these mistakes

  • Do not start antibiotics without a proper medical decision.
  • Do not use steroid tablets or injections casually for quick relief.
  • Do not delay emergency care because of home remedies.

Get urgent help if

  • Severe symptoms, confusion, fainting, breathing difficulty, chest pain, severe dehydration, or sudden weakness need urgent medical care.
Medicine names, dose, and timing must be decided by a qualified clinician or pharmacist after checking age, pregnancy, allergy, other diseases, and current medicines.

For rural patients and family caregivers

Patient health record and symptom diary

Write your symptoms, medicines already taken, test results, and questions before visiting a doctor. This note stays on your device unless you print or copy it.

Doctor to discuss: Doctor / qualified healthcare provider
Tests to discuss with doctor
  • Basic vital signs: temperature, pulse, blood pressure, oxygen level if needed
  • Relevant blood, urine, imaging, or specialist tests only after clinical assessment
Questions to ask
  • What is the most likely cause of my symptoms?
  • Which warning signs mean I should go to emergency care?
  • Which tests are really needed now?
  • Which medicines are safe for my age, pregnancy status, allergy, kidney/liver/stomach condition, and current medicines?

Emergency warning signs such as chest pain, severe breathing difficulty, sudden weakness, confusion, severe dehydration, major injury, or loss of bladder/bowel control need urgent medical care. Do not wait for online information.

Safe pathway to proper treatment

Care roadmap for: Endoscopic Ultrasound – Indications, Procedures, Results

Use this simple roadmap to understand the next safe steps. It is educational and does not replace examination by a doctor.

Go to emergency care if you notice:
  • Severe or rapidly worsening symptoms
  • Breathing difficulty, chest pain, fainting, confusion, severe weakness, major injury, or severe dehydration
Doctor / service to discuss: Qualified healthcare provider; specialist depends on symptoms and examination.
  1. Step 1

    Check danger signs first

    If danger signs are present, seek emergency care and do not wait for online information.

  2. Step 2

    Record the symptom story

    Write when symptoms started, severity, medicines already taken, allergies, pregnancy status, and test results.

  3. Step 3

    Visit a qualified clinician

    A doctor, nurse, or qualified healthcare provider can examine you and decide which tests or treatment are needed.

  4. Step 4

    Do only useful tests

    Do tests after clinical assessment. Avoid unnecessary tests, random antibiotics, or repeated medicines without diagnosis.

  5. Step 5

    Follow up and return early if worse

    If symptoms worsen, new warning signs appear, or treatment is not helping, return for review quickly.

Rural patient practical tips
  • Take a written symptom diary and all previous prescriptions/test reports.
  • Do not hide medicines already taken, even herbal or over-the-counter medicines.
  • Ask which warning signs mean urgent referral to hospital.

This roadmap is for education. A real diagnosis and treatment plan requires history, examination, and clinical judgment.
