What is Endoscopic Ultrasound?

Endoscopic ultrasound combines endoscopy and ultrasound to evaluate the internal organs of the chest and abdomen. EUS is a minimally invasive procedure, similar to a standard upper endoscopy. The close proximity of the ultrasound to the internal organs and tissue provides highly detailed images. These images can be used to help diagnose and determine the extent of spread for certain types of cancer including lung, esophageal, stomach, pancreatic, bile duct, and rectal. EUS is also an important tool in the management of pancreatic cysts, intestinal nodules, gallstones, unexplained pancreatitis, chronic abdominal pain, and bowel incontinence.
