Understanding EUS (Endoscopic Ultrasound)

EUS combines endoscopy and ultrasound to obtain high-resolution images of the digestive tract and surrounding tissues.

How does it work? A special endoscope with an ultrasound probe is inserted into the digestive tract. Sound waves create detailed images of internal organs and lymph nodes.

Why is it performed?

• Diagnose tumors in the digestive tract and nearby organs
• Stage cancers
• Guide fine needle aspiration (FNA) for biopsies
• Evaluate unexplained abdominal pain

Side Effects:

• Mild throat discomfort
• Rarely, bleeding, infection, or perforation
