EUS is ultrasound of internal structures surrounding the GI tract with the help of endoscope. EUS provides excellent resolution of pancreas, biliary system and the mediastinum.
EUS is performed by oral route after conscious sedation.
During EUS, sample can be taken from the nodes in mediastinum, tumor of pancreas and bile duct. With the help of endoscopic ultrasound various collections can be drained internally in the stomach or rectum and the major surgeries can be avoided.
