Endoscopic Ultrasound Provides a Better Look into Solid Tissue

An endoscopic ultrasound, or EUS, combines two ways of imaging: upper endoscopy and ultrasound. A small ultrasound probe on the end of the endoscope produces sound waves, which are translated into images. This allows the doctor to see further into solid tissues where an endoscope cannot travel. In addition to providing a better look, EUS can be used to take tissue samples for biopsy, drain cysts and deliver medications directly to organs.

EUS is helpful for examining several digestive conditions, including:

  • Barrett’s esophagus
  • Bile duct stones
  • Cancer
    (colorectal, esophageal, pancreatic, liver or stomach)
  • Pancreatitis
  • Pancreatic cysts

EUS is especially helpful for looking at potentially cancerous tumors, masses and growths. EUS is often combined with fine needle aspiration (FNA), in which a thin, hollow needle is inserted into suspicious areas. When the needle is removed, it has collected several layers of tissue samples. This process is painless. Because FNA is done with ultrasound guidance, the doctor knows exactly which areas should be sampled. The tissue samples can be studied under a microscope to determine if they are cancerous or not. Without EUS and FNA, an exploratory surgery would need to be performed.

Preparing for an EUS is the same as preparing for an upper endoscopy and involves fasting and pausing certain medications. The entire EUS procedure takes about one hour, and patients can return home after a brief observation period following the procedure. The risks associated with EUS are similar to those of other endoscopic procedures. There is a slight risk for bleeding, infection or tearing of the digestive tract. These risks are minimized when seeking care from a doctor highly experienced in endoscopy such as one at AdventHealth Digestive Health Institute. If fine needle aspiration has been done on the pancreas, there is a small risk for pancreatitis, or inflammation of the pancreas.
