What is EUS?
Endoscopic Ultrasound (EUS) is an advanced, minimally invasive procedure that combines endoscopy (a thin flexible tube with a camera) and ultrasound (sound waves that create images of internal organs).
This powerful combination helps doctors examine the esophagus, stomach, pancreas, liver, gallbladder, and lymph nodes with exceptional clarity — and even take tissue samples if needed.
Why is EUS Performed?
EUS helps in both diagnosis and staging of various gastrointestinal and pancreatic conditions, including:
Pancreatic tumors or cysts
Gallstones and bile duct disorders
Esophageal or stomach cancers
Chronic pancreatitis and abdominal pain
Evaluation of lymph nodes and cancer spread
How is the Procedure Done?
EUS is usually performed under sedation for comfort. A thin endoscope with an ultrasound probe is gently passed through the mouth into the digestive tract.
The ultrasound component generates high-resolution images of the surrounding organs. If a suspicious area is found, a fine needle aspiration (EUS-FNA) can be done through the same scope to collect tissue samples — all in one sitting.
Advantages of EUS
✅ Highly accurate imaging of digestive and pancreatic organs
✅ Detects very small lesions missed by other scans
✅ Helps avoid unnecessary surgery
✅ Allows biopsy and drainage procedures safely
✅ Fast recovery – most patients go home the same day
