Endoscopic Ultrasound

Share:

Endoscopic ultrasounds (EUS) are used to evaluate conditions and diseases affecting the gastrointestinal tract. Using an endoscope, which is a small, flexible tube with a light and camera attached to it, doctors are able to obtain digital ultrasound images of the upper and lower digestive system. The images received are of high quality because the EUS transducer is able to get very close to the organ(s) being examined.

Endoscopic ultrasounds are commonly used to:

  • Evaluate abnormalities found in organs of the digestive tract (liver, gallbladder, etc.)
  • Examine nodules found in the wall of the intestine
  • Determine the stage of cancer
  • Diagnose chronic pancreatitis
  • Examine the lower rectum and anal canal

How to Prepare for the Procedure

Please refrain from eating or drinking anything at least four to six hours prior to your appointment so your system will be empty, allowing us to capture as clear of images as possible. Please inform us of any medications you are currently taking so we can instruct you if any changes need to be made in your dosages prior to your procedure.

What to Expect During the Procedure

An endoscopic ultrasound is a non-invasive procedure that takes between 30 and 90 minutes. A mild sedative will be used to help the patient relax before the doctor inserts the endoscope into the rectum. The EUS transducer will transmit images of the digestive tract onto a monitor for the doctor to thoroughly examine the area.

What to Expect After the Procedure

After the sedative has worn off, we will provide you with a summary of the ultrasound, as well as give you photographs to view. If a biopsy was taken during the procedure, we will inform you of the lab results within a few days. We will also discuss and schedule any necessary follow up appointments.

Please have someone accompany you to your appointment so they can drive you home. Other than refraining from driving for 24 hours, you can return to your normal daily activities after your appointment.
