Endoscopic Ultrasound

Ultrasonography is a method frequently used in clinical practice, especially in the diagnosis of digestive system diseases. Although it is similar to X-ray with its imaging feature, it does not contain radiation.
Since EUS shows the wall layers in the digestive system in detail, it is used in the staging of tumours in the digestive system or organs adjacent to the digestive system (size and depth of the tumour, lymph node and adjacent organ metastasis, etc.) and in the examination of lesions located under the epithelium in the digestive system.

Tissue sample can be taken

It is a very helpful method especially in the evaluation of the oesophagus, stomach, pancreas and biliary tract and is superior to other imaging methods depending on the location. With EUS, tissue samples can be taken from tumours originating from the digestive system and organs adjacent to the digestive system; cysts etc. formations can be drained (Interventional EUS)

How is it done?

EUS is performed by placing a mini ultrasonography device that emits and records sound waves at the end of the devices called endoscopes used in digestive system endoscopy.
