EUS (Endoscopic Ultrasound)

There are many different tests which can be used to evaluate the pancreas. CT scans and MRI are types on non-invasive tests which allow for detailed imaging of the pancreas and the surrounding structures in the abdominal cavity. CT scans expose the patient to some amount of radiation. Furthermore, some patients are unable to receive IV contrast for their CT scans (due to allergies or kidney problems), and thus the quality of the pictures will be sub-optimal. A special kind of MRI called an MRCP can give high-quality pictures of the pancreas, the pancreas duct, and the bile ducts. However, some patients who are claustrophobic may decide against having an MRI performed.

As discussed, EUS allows the physician to get in very close proximity to the pancreas, which results in very detailed imaging of the organ. The endoscopist can often times visualize details of the pancreas that cannot be seen with either CT or MRCP. Furthermore, there is no exposure to radiation and no need for contrast to be given. In addition, because the EUS scope has a video camera on it, endoscopic evaluation of the esophagus, stomach, and first part of the small intestine can also be evaluated at the time of the EUS. This is important for some patients who are having a work-up for abdominal pain as it allows for a complete examination of the upper GI system.

The biggest advantage of EUS is that, unlike with CT or MRCP, pancreatic biopsies can be safely and easily obtained at the time of the exam.

After the EUS procedure, the patient remains in the recovery room until the sedative medicine has worn off. The patient should not drive a vehicle after the procedure.

Patients may feel full or the need to pass gas after the procedure. Also, the patient may have changes in bowel habits, such as soft stool. The healthcare team provides instructions on eating and drinking after an EUS.

Call your doctor immediately or go to an emergency room if you experience any of the following signs or symptoms:

– Fever

– Chest pain

– Shortness of breath

– Black or very dark-colored stool

– Severe or persistent abdominal pain
