Endoscopic Ultrasound

Endoscopic ultrasound is a minimally invasive procedure in order to assess the digestive and lung diseases. This uses high-frequency sound waves that produces detailed images of the lining as well as the walls of your chest and digestive tract, nearby organs like the liver and pancreas, and lymph nodes.

EUS when combined with a procedure called fine-needle aspiration, it allows your healthcare professional to biopsy the fluid and tissue from your chest or abdomen for analysis. With fine-needle aspiration, EUS can be a minimally invasive alternative to the exploratory surgery.

EUS techniques are used in specific treatments, like draining pseudocysts.

Also, EUS is used to find the cause of symptoms like abdominal or chest pain, in order to determine the extent of diseases in your digestive tract and lungs, and to evaluate findings from imaging tests like MRI or CT scan.

EUS can help in the evaluation of:

Cancer of the colon, lung, pancreas or stomach, esophagus, and ampullary and rectal cancers

Barrett's esophagus

Neuroendocrine tumors

Lymphoma

Pancreatitis and pancreatic cysts

Rectal fistulas and fecal incontinence

Bile duct stones

Sarcoidosis
