Your doctor has recommended that you have
a lower GI endoscopy. But what does that actually mean? A lower GI endoscopy is a diagnostic procedure
used by your doctor to inspect the inside of your rectum and colon. While it’s considered
a surgical procedure, endoscopy does not involve an incision. Instead, your doctor will pass a flexible
tube, called an endoscope through your anus and into your rectum and colon. This tube has a tiny video camera mounted
on its tip. It also contains a small tool used for taking
tissue samples. Your doctor can use the endoscope to inspect
the entire lower half of your digestive system. Your doctor can use the endoscope to inspect
the entire lower half of your digestive system. Movie In some cases, the shape of the colon makes
it impossible to pass the endoscope as far into the body as the doctor would like. Your doctor may decide to take a series of
x-rays – or even to perform surgery – in order to inspect the hidden area. Reasons for undergoing a lower GI endoscopy
vary. You may have been suffering from one or more of a number symptoms – including blood
in your stool, weight loss, chronic irregularity or other problems associated with the digestive
system. Some gastrointestinal symptoms can be warning
signs of serious medical problems and you should take your doctor’s recommendation to
have an endoscopy very seriously. Luckily, the vast majority of medical problems
diagnosed by endoscopy are treatable and you should look forward to improved health and
comfort as a result of the information gathered during the procedure. The doctor will then lubricate your rectum
and gently insert the endoscope, guiding it into your colon. You may feel some pressure or tugging, but
you shouldn’t feel pain. To better examine abnormal-looking tissues,
your doctor may choose to take one or more biopsies. Small instruments sent through the interior
of the endoscope are able to painlessly remove small samples of tissue with a small scissor
like tool by simply snipping them free. Finally, after a thorough exam, the endoscope
is carefully removed. Any tissue specimens removed during the procedure
will be sent immediately to a lab for microscopic analysis. Your doctor will tell you when to
expect results from those tests.
