Endoscopic Ultrasound

 Endoscopic ultrasound (EUS) or echo-endoscopy is a medical process in which endoscopy (insertion of a probe into a hollow organ) is joint with ultrasound to gain images of the internal organs in the chest, abdomen and colon. It can be used to imagine the walls of these organs, or to look at adjacent structures. Joint with Doppler imaging, nearby blood vessels can also be appraised. Endoscopic ultrasonography is most usually used in the upper digestive tract and in the respiratory system. The process is achieved by gastroenterologists or pulmonologists who have had extensive training. For the patient, the procedure textures almost identical to the endoscopic process without the ultrasound part, unless ultrasound-guided biopsy of deeper assemblies is performed. For endoscopic ultrasound of the upper digestive tract, a probe is implanted into the esophagus, stomach, and duodenum during a procedure called esophagogastroduodenoscopy. Among other uses, it permits for screening for pancreatic cancer, esophageal cancer, and gastric cancer, as well as benign tumors of the upper gastrointestinal tract. It also allows for characterization and biopsy of any focal lesions originate in the upper gastrointestinal tract, such as esophageal tuberculosis.This is done by implanting a needle through the stomach lining into the target. Less commonly this procedure is used to classify malformations and masses in the bile ducts and pancreatic ducts.
