Endoscopic Ultrasonography (EUS)

Endoscopic Ultrasonography (EUS)

EUS is a method based on ultrasound. An endoscope is used that provides a clear view of internal structures surrounding the GI tract.

It provides an excellent view of internal parts such as the biliary system, pancreas, and mediastinum.

Technique

After conscious sedation, EUS is conducted via an oral route.

The sample is obtained from the suspected lesions including nodes in the mediastinum, and tumorous tissue of biliary duct and pancreas.

An internal drainage of various collections is possible, draining into the stomach or rectum. Thus, complicated and invasive surgeries can be avoided.

Indications

Evaluation and samples of adrenal gland, chest and abdominal nodes.

Assessment of dilated CBD without any underlying cause

Sampling of pancreatic mass or CBD

Drainage of collection internally

In Patients with chronic pancreatitis provides pain relief (Celiac plexus block)

In failed cases of ERCP allows stent placement in the CBD or liver
