Endoscopic Ultrasound

EUS is one type of a minimally invasive endoscopic examination to assess digestive (gastrointestinal) and lung diseases. In this procedure a thin tube is inserted into the mouth through the stomach to the first part of the small intestine. This tube is a small ultrasound probe at its tip that emits sound waves. The reflected ultra-sound waves are then recaptured by the probe to form detailed black & white images and the images are interpreted by your doctor.

This procedure (EUS)is used to find out:

  • Cause of abdominal or chest pain
  • More information pertaining to CT scan or MRI reports
  • Cancer of the colon, esophagus, lung, pancreas or stomach
  • Lymphoma
  • Barrett's esophagus
  • Neuroendocrine tumors
  • Pancreatitis and pancreatic cysts
  • Bile duct stones
  • Sarcoidosis

You need to disclose your current medications if any you are on and you are required fasting for 6-8 hours prior to the procedure.

Typically, the procedure is performed in an outpatient environment and the duration of the procedure may vary between 20 and 45 minutes.

EUS is considered as a low-risk procedure. However, the procedure may bring some complications, such as:

– Perforation (tear in the gut wall)

– Inflammation of the pancreas

– Reaction to sedation

– Infection

– Bleeding

One may feel bloated after the procedure. This will subside after 2-3 days.
