Endoscopic Ultrasound (EUS) is a minimally invasive procedure that combines endoscopy (a thin, flexible tube with a camera) and ultrasound (sound waves) to get highly detailed images of the digestive tract and nearby organs such as the pancreas, liver, and bile ducts. EUS is also used to take tissue samples (biopsies) and guide certain treatments.
EUS is a procedure where a special endoscope with an ultrasound probe is inserted through the mouth or rectum. It provides clear images of the digestive tract lining and surrounding organs, making it more precise than regular ultrasound or CT scans for certain conditions.
EUS helps diagnose and stage conditions such as:
It can also guide fine needle aspiration (FNA) to collect tissue samples for biopsy.
EUS is usually done under sedation. A flexible tube is inserted through the mouth (for upper GI tract and pancreas) or rectum (for rectum and lower colon). The ultrasound probe at the tip creates detailed images, and if needed, a needle can be passed through the scope for tissue sampling.
No. Patients are sedated or under anesthesia during the procedure, so they do not feel pain. Some mild sore throat, bloating, or discomfort may occur afterward but usually resolves quickly.
EUS is generally safe. Rare risks include bleeding, infection, perforation of the digestive tract, or complications from sedation. If a biopsy or drainage is performed, the risks may be slightly higher but still uncommon.
The procedure usually takes 30–60 minutes. Most patients go home the same day. Normal activities can be resumed within 24 hours, though patients should avoid driving until sedation fully wears off.
