EUS (Endoultrasonography)

EUS or endoscopic ultrasound implies visualizing visceral organs using ultrasound probes equipped on one end of imaging devices that are specialized in digestive system endoscopy.

It is used to grade tumors of digestive system and adjacent organs (stomach, intestines, gall bladder, liver, and pancreas) and to assess lesions located immediately beneath the lining of digestive system.

EUS allows biopsying tumors that begin in digestive system and nearby organs and draining certain formations, such as cysts.

It is almost identical to a conventional endoscopy. It can assess both upper and lower digestive system. It is superior to other sonographic modalities in diagnosis of cancers of esophagus, stomach, pancreas, colon and biliary tree and assessment of vascular structures in these organs.
