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
