Colonoscopy in Iran


A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum.

During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon.

If necessary, polyps or other types of abnormal tissue can be removed through the scope during a colonoscopy. Tissue samples (biopsies) can be taken during a colonoscopy as well.

Why it's done

Your doctor may recommend a colonoscopy to:

  • Investigate intestinal signs and symptoms.A colonoscopy can help your doctor explore possible causes of abdominal pain, rectal bleeding, chronic constipation, chronic diarrhea and other intestinal problems.
  • Screen for colon cancer.If you're age 50 or older and at average risk of colon cancer — you have no colon cancer risk factors other than age — your doctor may recommend a colonoscopy every 10 years or sometimes sooner to screen for colon cancer. Colonoscopy is one option for colon cancer screening. Talk with your doctor about your options.
  • Look for more polyps.If you have had polyps before, your doctor may recommend a follow-up colonoscopy to look for and remove any additional polyps. This is done to reduce your risk of colon cancer.

How is a colonoscopy done?

During a colonoscopy, the doctor uses a colonoscope, a long, flexible, tubular instrument about 1/2-inch in diameter that transmits an image of the lining of the colon so the doctor can examine it for any abnormalities. The colonoscope is inserted through the rectum and advanced to the other end of the large intestine.

Why do doctors use colonoscopy?

A colonoscopy can help a doctor find the cause of symptoms, such as

  • bleeding from your anus
  • changes in your bowel activity, such as diarrhea
  • pain in your abdomen
  • unexplained weight loss

 What a colonoscopy is looking for

A colonoscopy can be done to look for a number of things.

The cause of your bowel symptoms

A colonoscopy is often done to check what's causing your bowel symptoms, such as:

  • bleeding from your bottom or blood in your poo
  • diarrhea or constipation that does not go away
  • losing weight or feeling really tired for no reason

Most of the time it will not find anything to worry about.

But sometimes it might find something that needs a closer look or further testing.

Growths in your bowels (polyps)

Lots of people have growths in their bowels, and most of the time they're harmless. But they can sometimes become cancer, so if they're found they need to be checked.

They can be removed during the colonoscopy and tested.

Your results will tell you if you need any further tests or treatment.

Before a Colonoscopy

Before a colonoscopy, let your doctor know about any special medical conditions you have, including the following:

  • Pregnancy
  • Lung conditions
  • Heart conditions
  • Allergies to any medications
  • If you have diabetes or take medications that may affect blood clotting; adjustments to these medications may be required before the colonoscopy.

What should I expect during colonoscopy?

Prior to colonoscopy, intravenous fluids are started, and the patient is placed on a monitor for continuous monitoring of heart rhythm and blood pressure as well as oxygen in the blood. Medications (sedatives) usually are given through an intravenous line so the patient becomes sleepy and relaxed, and to reduce pain. If needed, the patient may receive additional doses of medication during the procedure. Colonoscopy often produces a feeling of pressure, cramping, and bloating in the abdomen; however, with the aid of medications, it is generally well-tolerated and infrequently causes severe pain.

After a Colonoscopy

After your colonoscopy:

  • You will stay in a recovery room for about 30 minutes for observation
  • You may feel some cramping or a sensation of having gas, but this usually passes quickly
  • You can resume your normal diet

possible risks, complications, or alternatives to colonoscopy

Complications of colonoscopy are rare and usually minor when performed by physicians who have been specially trained and are experienced in colonoscopy.

Bleeding may occur at the site of biopsy or removal of polyps, but the bleeding usually is minor and self-limited or can be controlled through the colonoscope. It is quite unusual to require transfusions or surgery for post-colonoscopic bleeding. An even less common complication is a perforation or a tear through the colonic wall, but even these perforations may not require surgery.

Other potential complications are reactions to the sedatives used, localized irritation to the vein where medications were injected (leaving a tender lump lasting a day or two), or complications from existing heart or lung disease. The incidence of all of these complications together is less than 1%.

While these complications are rare, it is important for patients to recognize early signs of a complication so that they may return to their physicians or an emergency room. The colonoscopist who performed the colonoscopy should be contacted if a patient notices severe abdominal pain, rectal bleeding of more than half a cup, or fever and chills.
