EUS
Combines endoscopy with ultrasound to image organs adjacent to the digestive tract. Particularly valuable for pancreatic evaluation, lymph node sampling, and staging certain cancers.
EUS places a tiny ultrasound probe at the tip of an endoscope, giving close-range, high-resolution images of structures next to the gut wall.
It is the test of choice for the pancreas, the deep layers of the gut wall, and small lesions that are difficult to see on a CT scan.
Performed under sedation, like an upper endoscopy.
When a target lesion is identified, a thin needle (FNAB) can be passed through the scope to take a tissue sample.
Therapeutic EUS can drain pancreatic fluid collections or create a route to the bile duct when conventional ERCP is not possible.
All endoscopic procedures carry a small risk of bleeding, perforation, or reaction to sedation. These risks are uncommon when the procedure is done by a trained endoscopist in a hospital setting.
We will explain the risks specific to your case during the consultation, before you sign consent.
Common questions
How is EUS different from CT or MRI?
EUS gets closer to the target, so it can see smaller and deeper details, and it allows sampling in the same sitting.
