CAPSULE
ENDOSCOPY
Unavailable
Capsule
endoscopy (en DOS-skuh-pee) enables the physician to look inside the
esophagus, stomach, and small intestine but is primarily designed
for the small intestine or esophagus. The procedure might be used
to discover a source of bleeding suspected to be in the small bowel,
diagnose Crohn’s
disease or screen for Barrett’s
change of the esophagus.
For the procedure you will swallow a small capsule, about the size
of a glucosamine tablet. This will transmit images to storage device
that you wear. Right before the procedure the nurse will attach
a sensor array to your chest (Esophageal Capsule) or abdomen (Small
Bowel Capsule) using sticky pads similar to those used for an EKG
of your heart. A vest containing a small hard drive and batteries
is then worn. The capsule transmits an image of the esophagus or
small bowel to the hard drive over the course of 8 hours, so the
physician can carefully examine the lining of these organs. The
test is begun in the morning and you are able to leave the physicians
office, returning in the afternoon to drop off the vest. The process
is completely painless and the capsule does not need to be retrieved,
passing naturally in the next few days. The physician then uses
special software to create a movie from the images obtained which
is then reviewed.
The capsule takes 2 pictures each second for up to 8 hours. The
physician can see abnormalities, like angioectasia, ulcers or tumors
that don't show up well on x rays. No biopsies or treatments can
currently be performed. A possible complication of capsule endoscopy
is capsule retention. This occurs rarely in patients with intestinal
strictures, either from past inflammatory intestinal diseases or
bowel resections. However, such complication is very uncommon. Most
people will not notice the capsule at all. No sedation is
needed.
COLONOSCOPY
Colonoscopy
(koh-luh-NAH-skuh-pee) lets the physician look inside your entire
large intestine, from the lowest part, the rectum, all the way up
through the colon to the lower end of the small intestine. The procedure
is used to look for early signs of cancer in the colon and rectum.
It is also used to diagnose the causes of unexplained changes in bowel
habits. Colonoscopy enables the physician to see inflamed tissue,
abnormal growths, ulcers, and bleeding.
For the procedure, you will lie on your left side on the examining
table. You will probably be given pain medication and a mild sedative
to keep you comfortable and to help you relax during the exam. The
physician will insert a long, flexible, lighted tube into your rectum
and slowly guide it into your colon. The tube is called a colonoscope
(koh-LON-oh-skope). The scope transmits an image of the inside of
the colon, so the physician can carefully examine the lining of
the colon. The scope bends, so the physician can move it around
the curves of your colon. You may be asked to change position occasionally
to help the physician move the scope. The scope also blows air into
your colon, which inflates the colon and helps the physician see
better.
If anything abnormal is seen in your colon, like a polyp or inflamed
tissue, the physician can remove all or part of it using tiny instruments
passed through the scope. That tissue (biopsy) is then sent to a
lab for testing. If there is bleeding in the colon, the physician
can pass a laser, heater probe, or electrical probe, or can inject
special medicines through the scope and use it to stop the bleeding.
Bleeding and puncture of the colon are possible complications of
colonoscopy. However, such complications are uncommon.
Colonoscopy takes 30 to 60 minutes. The sedative and pain medicine
should keep you from feeling much discomfort during the exam. You
will need to remain at the facility until a nurse releases you to
your driver.
Upper
endoscopy enables the physician to look inside the esophagus, stomach,
and duodenum (first part of the small intestine). The procedure might
be used to discover the reason for swallowing difficulties, nausea,
vomiting, reflux, bleeding, indigestion, abdominal pain, or chest
pain. Upper endoscopy is also called EGD, which stands for esophagogastroduodenoscopy
(eh-SAH-fuh-goh-GAS-troh-doo-AH-duh-NAH-skuh-pee).
For the procedure you will swallow a thin, flexible, lighted tube
called an endoscope (EN-doh-skope). Right before the procedure the
physician will spray your throat with a numbing agent that may help
prevent gagging. You may also receive pain medicine and a sedative
to help you relax during the exam. The endoscope transmits an image
of the inside of the esophagus, stomach, and duodenum, so the physician
can carefully examine the lining of these organs. The scope also
blows air into the stomach; this expands the folds of tissue and
makes it easier for the physician to examine the stomach.
The physician can see abnormalities, like inflammation or bleeding,
through the endoscope that don't show up well on x rays. The physician
can also insert instruments into the scope to treat bleeding abnormalities
or remove samples of tissue (biopsy) for further tests.
Possible complications of upper endoscopy include bleeding and
puncture of the stomach lining. However, such complications are
rare. Most people will probably have nothing more than a mild sore
throat after the procedure. The procedure takes 20 to 30 minutes.
Because you will be sedated, you will need to rest at the facility
until a nurse releases you to your driver.
Endoscopic
retrograde cholangiopancreatography (en-doh-SKAH-pik REH-troh-grayd
koh-LAN-jee-oh-PANG-kree-uh-TAH-gruh-fee) (ERCP) enables the physician
to diagnose problems in the liver, gallbladder, bile ducts, and pancreas.
The liver is a large organ that, among other things, makes a liquid
called bile that helps with digestion. The gallbladder is a small,
pear-shaped organ that stores bile until it is needed for digestion.
The bile ducts are tubes that carry bile from the liver to the gallbladder
and small intestine. These ducts are sometimes called the biliary
tree. The pancreas is a large gland that produces chemicals that help
with digestion and hormones such as insulin.
ERCP is used primarily to diagnose and treat conditions of the
bile ducts, including gallstones, inflammatory strictures (scars),
leaks (from trauma and surgery), and cancer. ERCP combines the use
of x rays and an endoscope, which is a long, flexible, lighted tube.
Through the endoscope, the physician can see the inside of the stomach
and duodenum, and inject dyes into the ducts in the biliary tree
and pancreas to be seen on x rays.
For the procedure, you will lie on your left side on an examining
table in an x-ray room. You will be given medication to help numb
the back of your throat and a sedative to help you relax during
the exam. You will swallow the endoscope, and the physician will
then guide the scope through your esophagus, stomach, and duodenum
until it reaches the spot where the ducts of the biliary tree and
pancreas open into the duodenum. At this time, you will be turned
to lie flat on your stomach, and the physician will pass a small
plastic tube through the scope. Through the tube, the physician
will inject a dye into the ducts to make them show up clearly on
x rays. X rays are taken as soon as the dye is injected. If the
exam shows a gallstone or narrowing of the ducts, the physician
can insert instruments into the scope to remove or relieve the obstruction.
Also, tissue samples (biopsy) can be taken for further testing.
Possible complications of ERCP include pancreatitis (inflammation
of the pancreas), infection, bleeding, and perforation of the duodenum.
Except for pancreatitis, such problems are uncommon. You may have
tenderness or a lump where the sedative was injected, but that should
go away in a few days.
ERCP takes 30 minutes to 2 hours. You may have some discomfort
when the physician blows air into the duodenum and injects the dye
into the ducts. However, the pain medicine and sedative should keep
you from feeling too much discomfort. After the procedure, you will
need to stay at the hospital for 1 to 2 hours until the sedative
wears off. The physician will make sure you do not have signs of
complications before you leave. If any kind of treatment is done
during ERCP, such as removing a gallstone, you may need to stay
in the hospital overnight.
Flexible
sigmoidoscopy (SIG-moy-DAH-skuh-pee) enables the physician to look
at the inside of the large intestine from the rectum through the last
part of the colon, called the sigmoid or descending colon. Physicians
may use the procedure to find the cause of diarrhea, abdominal pain,
or constipation. They also use it to look for early signs of cancer
in the descending colon and rectum. With flexible sigmoidoscopy, the
physician can see bleeding, inflammation, abnormal growths, and ulcers
in the descending colon and rectum. Flexible sigmoidoscopy is not
sufficient to detect polyps or cancer in the ascending or transverse
colon (two-thirds of the colon).
For the procedure, you will lie on your left side on the examining
table. The physician will insert a short, flexible, lighted tube
into your rectum and slowly guide it into your colon. The tube is
called a sigmoidoscope (sig-MOY-duh-skope). The scope transmits
an image of the inside of the rectum and colon, so the physician
can carefully examine the lining of these organs. The scope also
blows air into these organs, which inflates them and helps the physician
see better.
If anything unusual is in your rectum or colon, like a polyp or
inflamed tissue, the physician can remove a piece of it using instruments
inserted into the scope. The physician will send that piece of tissue
(biopsy) to the lab for testing. Bleeding and puncture of the colon
are possible complications of sigmoidoscopy. However, such complications
are uncommon.
Flexible sigmoidoscopy takes 10 to 20 minutes. During the procedure,
you might feel pressure and slight cramping in your lower abdomen.
You will feel better afterward when the air leaves your colon.
