ColonoscopyColonoscopy is a screening
test to view the interior lining of the large intestine (rectum and colon) through
a thin, flexible tube fixed with a fibre optic camera called a colonoscope.
This test is used to detect problems or diseases of the anus, rectum, or
large intestine. This test is usually performed for evaluating the causes of abdominal
pain, bleeding or pus in the stool, anemia, prolonged constipation or diarrhea
and as a screen test for colon cancer or polyps. During a colonoscopy, tissue
samples can be collected and abnormal growths can be removed. Care
before the test
This generally involves taking some kinds of laxatives
prescribed by the doctor to cleanse out the colon one day prior to the test. It
is better to avoid eating solid food and drink only clear fluids one or two days
before the test. Inform your doctor whether you are taking medications like insulin,
iron pills and any blood thinners, you are allergic to any medications, you have
had an X-ray test using barium contrast material within the past 4 days, you are
or might be pregnant and about any prior surgeries in the abdomen or a heart-valve
infection that you have had. You may be advised to avoid taking aspirin or
nonsteroidal anti-inflammatory drugs for several days before the test to reduce
the risk of bleeding if any biopsy sample needs to be taken. How
the test is done
Before colonoscopy is done sedatives will be given to
make the person more comfortable during the procedure. The person is made to lie
on one side with knees flexed toward the abdomen. First a rectal exam with the
finger is done and then the colonoscope is inserted through the anus into the
large intestine. The instrument is advanced through the colon until it comes to
the place where the colon meets the small intestine, on the right lower part of
the abdomen. Then air is passed through the colonoscope to gently inflate
the colon for a clear view of the entire circumference of the wall of the colon
on a TV monitor. Additional sedatives may be given if needed.
If
any abnormalities are seen, photographs and a biopsy or a tissue sample may be
taken. Colonoscopy is also used to remove small colorectal polyps. Risks
Complications from colonoscopy are rare. There is a slight risk of puncturing
the colon or causing severe bleeding by damaging the wall of the colon and cardiac,
respiratory and blood pressure problems. There is also a slight risk of causing
a colon infection. Age for testing
Screening
test for colon cancer is recommended after age 50. Colonoscopy once every 5 or
even 10 years is one way to have this screening done.

It seems there was a bing hole in my right ear drum and I had a mild earing loss (conductive losses). As advised by the ENT Surgeon, I underwent CT scan too. He suggested me to undergo surgery by which my mastoid bone has to be open and all infection there has to be removed. I had the hole in the ear drum for the past 25 years and so far I had no problem except mild hearing loss. No ear discharge for the past 15 years. Even earlier also I used to have ear discharge very rarely. ENT surgeon suggested me to undergo the surgery what is called Mastoidectomy. I unable to take a call whether I should undergo surgery now or postpone to a time when I notice any further problem. I would like to know whether the problem gets aggravated if I do not undergo surgery. Whether it prevents further deterioation and improves the hearing? Kindly advise.

hi babu, as u told that you have a hole in your ear drum, which is a connection between the external and the middle ear, thus making the middle ear prone to repeated infections. middle ear infections can become very severe when they become chronic which can also lead to permanent and conductive hearing loss. so it is advisable for you to not to wait and undergo mastoidectomy. gud luck. | |
