Endoscopic Ultrasound (EUS)

Endoscopic ultrasound is an advanced hybrid procedure that combines endoscopy and ultrasound technology to provide highly detailed imaging of the digestive tract and surrounding structures. This technique allows physicians not only to visualize the inner lining of the gastrointestinal tract but also to assess deeper layers and nearby organs with exceptional precision.

What is it?
It is a specialized procedure in which an endoscope equipped with an ultrasound transducer at its tip is used to generate high-resolution images from inside the body.

Procedure Description:
During the procedure, the endoscope is introduced under sedation, either through the mouth or rectum depending on the area being evaluated. The integrated ultrasound probe enables clinicians to “see beyond” the digestive tract walls, offering detailed visualization of adjacent organs such as the pancreas, bile ducts, and lymph nodes.

This level of imaging surpasses that of conventional external ultrasound, making it particularly valuable for detecting tumors, cysts, inflammation, or other abnormalities. In many cases, it also allows for guided biopsies, improving diagnostic accuracy.

Endoscopic ultrasound is a key tool in the early detection, staging, and management of complex gastrointestinal and hepatobiliary conditions, supporting more precise and effective clinical decision-making.
