Flexible sigmoidoscopy vs. colonoscopy?
Sigmoidoscopy
To
get exact outcomes, both the rectum as well as the lower colon should be clean
and free of stool. Your doctor will provide you with detailed instructions on
how you can clean your colon. In general, this will require the usage either
one or two times prior to the procedure. It may also require a laxative as well
as certain dietary changes. If there are special situations, like the presence
of severe diarrhea, the procedure can be omitted.
It
is generally accepted that you are able to continue taking your normal
medication. It is important to inform your doctor about every prescription and
non-prescription drug you are taking and any other allergies you might have.
Certain medications can increase the risk of bleeding after colonoscopy when biopsies are done. These include
aspirin blood thinners like warfarin (Coumadin) and NSAIDs like Motrin or
Advil. The doctor might ask you to take off these drugs for a few days prior to
the procedure. It is also important to inform your doctor if you wear an
artificial valve for your heart, knee, or hip prosthesis, or suffer from any
heart valves, such as mitral stenosis, aortic orifice stenosis, and mitral
regurgitation. Patients suffering from these ailments may require antibiotics
prior to colonoscopy test dental
procedures to avoid infection of the heart valves and prostheses.
Colonoscopy
For
the operation going to be precise and thorough, the colon has to be thoroughly
cleaned. There are a variety of colonoscopy
preparations. Patients are provided with specific instructions on cleansing
procedures. It generally involves drinking a substantial quantity of a cleanser
or several days of a liquid diet that is clear and laxatives or enemas before
the test. This procedure should be carried out precisely as directed or the
test may prove insufficient (visualization of the colon's lining could be
obscured by the remnants of stool) the test may need to be repeated or a less
precise alternative test will be conducted in the place.
It
is also possible to instruct to avoid certain food items for a few days before
the surgery, for example, stringy foods or foods that contain seeds and red
jelly-o.
All
medications should be taken in the same manner; however certain medications may
cause interference with the exam. It is suggested that the colony scopiesknow
about all prescription and over-the counter medicines. Aspirin blood thinners
like warfarin (Coumadin) and arthritis medicines insulin, iron, and arthritis
preparations are a few examples of medicines that may require specific
directions. The colonoscopies also need to know about the patient's allergies,
as well as other serious illnesses. The colonoscopiesneed to be aware when
previously, patients required antibiotics prior to surgical or dental
procedures to avoid infection.
What happens during colonoscopy and
endoscopy procedures?
Sigmoidoscopy
Flexible
sigmoidoscopy can be tolerated and does not cause any major discomfort. There
could be a feeling in the form of bloating, fullness tension, or cramping
during the procedure. Most of the time you'll be lying to your right side as
the instrument is advancing through the rectum as well as the colon, while you
are looking directly at television monitors. After the instrument has been
removed and examined a careful note is conducted of the colon's lining. The
process typically takes about 5-15 minutes.
If
the doctor spots an area of the colon that requires an examination then a
biopsy (a small portion of tissue) is possible to obtain and then sent to the pathology division to be examined under
a microscope. If a polyp is discovered and removed by the doctor, they can
remove the one at the same time. Polyps are small, swollen growths within the
colon's lining and the rectum. The majority of Polyps have harmless (not
cancerous) however, some are precancerous. Polyps that are precancerous will
usually be asked for a colonoscopy following an additional vigorous colon
cleanse. Colonoscopy can be described as a longer form of flexible
sigmoidoscopy in which doctors examine the entire section of the colon. For
more details, refer to this Colonoscopy article. The benefit of colonoscopy
over flexible sigmoidoscopy lies in its capability to locate and eliminate
polyps from the areas of the colon that are out of the scope of sigmoidoscopy which
is flexible. Elimination of all precancerous polyps in colonoscopy has been
proven to reduce the risk of colon cancer.
Colonoscopy
Before
the colonic procedure, intravenous fluids are infused into the patient, and he
is put on a monitor for constant monitoring of the heart rate and blood
pressure, and oxygen levels of the blood. Drugs (sedatives) typically are
administered through an intravenous vein so the patient can fall asleep and relax.
They also help alleviate discomfort. If required, the patient might receive
additional doses of medication in the course of the procedure. A colonoscopy
biopsy causes the sensation of pressure, and abdominal bloating but
thanks to the use of medicines the procedure is usually well-tolerated and
rarely causes extreme discomfort.
Patients
lie on their left or back while the colonoscopy slowly advances. When the end
of the colon (cecum) or the end section of small the intestine (terminal the
ileum) is reached, the colonoscopy will be gradually removed, and the colon's
lining is examined carefully. Colonoscopy generally takes between 15 and 60
minutes. In the event that all of your colon because of some reason, is unable
to be seen, the doctor might opt to a do colonoscopy once more at a later time
with or without any other preparation for the bowel or decide to have an X-ray
and/or CT for the colon.
If
an abnormality must be evaluated the biopsy forceps may be inserted through a
canal inside the colonoscopy. A biopsy (a specimen of the tissue) can be taken.
The biopsy is then sent to the lab of pathology for analysis under a microscope
by the pathologist. If it is suspected that there is an infection it is
possible to have a biopsy taken to test the culturing process of bacteria.
