Endoscopic ultrasound is medical procedure where an endoscopically directed ultrasound is used to image thoracic and abdominal viscera.

The probe is inserted into the stomach and duodenum via esophagogastroduodenoscopy. Among other uses, it allows for screening for pancreatic cancer. It also allows for biopsing of any focal lesions found in the pancreas. This is done by inserting a needle through the stomach lining into the target.
