Tests for pancreatic cancer
Imaging tests
EUS (
e
ndoscopic
u
ltra
s
ound)
An EUS uses an endoscope that has a small ultrasound
probe at the end. The endoscope is inserted through
your mouth and guided down your throat and stomach
to the first part of the small intestine (duodenum).
The ultrasound probe bounces sound waves off your
pancreas and other organs to make pictures of the
inside of your body. EUS is often done to get a close
look at your pancreas and any tumor that might be in it.
EUS takes about 15 to 45 minutes. For this test, your
doctor will first give you a sedative—medicine to make
you feel relaxed or sleepy. After the test, your throat
may feel sore and you may feel bloated.
ERCP (
e
ndoscopic
r
etrograde
c
holangio
p
ancreatography)
An ERCP uses an endoscope and x-rays to make
pictures of the inside of the body. For this test, the
endoscope will be inserted through your mouth
and guided down your throat and stomach to the
duodenum. Next, a thinner tube called a catheter
will be passed through the middle of the endoscope.
The catheter will be used to inject a contrast dye into
the pancreatic and bile ducts.
See Figure 6.
Then,
an x-ray machine will take pictures. The contrast dye
allows the pancreatic and bile ducts to be clearly seen
on the x-ray pictures. An ERCP takes about 30 to 90
minutes. For this test, your doctor will first give you a
sedative—medicine to make you feel relaxed or sleepy.
After the test, your throat may feel sore and you may
feel bloated.
Laparoscopy
This test is a type of surgery that allows your doctors
to see organs in your belly area (abdomen). It uses
a laparoscope—a tool like an endoscope. For this
test, the laparoscope will be inserted through a tiny
cut in your abdomen. Laparoscopy is done under
general anesthesia—a controlled loss of wakefulness
from drugs. It is done in an operating room and takes
about 30 minutes. After the surgery, you may feel
tired and may have some pain. You may also have a
small scar after the cut has healed.
