Endoscopic Ultrasound (EUS) 

Endoscopic Ultrasound (EUS) is a minimally invasive procedure that combines endoscopy and ultrasound technology to provide detailed images of your digestive tract and surrounding organs, such as the pancreas, liver, and gallbladder. A small, flexible tube (endoscope) equipped with an ultrasound device is gently passed through your mouth and into your digestive system. This helps your doctor closely examine any potential issues without the need for surgery.

What are the Benefits of Endoscopic Ultrasound (EUS)?

  • Detailed Diagnosis: EUS offers highly accurate and clear images of your digestive organs, allowing for early detection of conditions such as diseases of the pancreas, bile duct, and gallbladder when other tests are inconclusive or conflicting. 
  • Minimally Invasive: The procedure is less invasive than traditional surgeries, reducing recovery time and discomfort. 
  • Precise Treatment Planning: EUS helps guide certain treatments or biopsies by pinpointing exact locations within your body. 

What are the Risks of Endoscopic Ultrasound (EUS)?

While EUS is generally safe, like any medical procedure, it does carry some risks. These include: 

  • Sore Throat: You may experience temporary soreness after the procedure. 
  • Bleeding or Infection: In rare cases, especially when a biopsy is performed, bleeding or infection may occur. 
  • Adverse Reaction to Sedation: Some patients may have mild reactions to the sedation used during the procedure. 

Your doctor will discuss any specific risks based on your health. 

What Should I Expect During an Endoscopic Ultrasound (EUS)?

  • Preparation: You will need to avoid food and drinks for several hours before the procedure to ensure a clear view. 
  • Sedation: To keep you comfortable, light sedation will be administered. You will be awake but relaxed. 
  • Procedure: The procedure usually lasts about 30-60 minutes. The doctor will gently guide the endoscope through your mouth and into your digestive tract while capturing detailed images. 
  • Recovery: After the procedure, you may rest for a short time as the sedation wears off. Most patients can go home the same day and return to normal activities within 24 hours. 

What are the Alternatives to an Endoscopic Ultrasound (EUS)?

If EUS is not recommended for you, alternatives like CT scans, MRIs, or standard ultrasound may be considered. However, these methods may not provide the same level of detail as an EUS. Your doctor will guide you on the best approach for your specific condition.

An EUS combines endoscopy and ultrasound to get detailed images of organs and tissues within your digestive tract. Unlike a standard ultrasound, which is done externally, an EUS uses a thin tube inserted through the mouth to bring the ultrasound probe closer to the target area, providing higher-resolution images.

An EUS offers a more detailed view, allowing doctors to assess not only the inner lining of your digestive tract but also nearby structures, like the pancreas, lymph nodes, and bile ducts. It’s particularly helpful for diagnosing complex issues or assessing the spread of certain conditions, like cancer.

Yes, EUS is considered safe, with a low risk of complications. Some mild side effects, like a sore throat or slight bloating, may occur but usually resolve quickly.
