A colonoscopy is an endoscopic test during which a lengthy, slim, flexible pipe or “scope” is moved through the anus and up through the length of the colon (large intestine). The scope has a light and a video camera on the tip of it, which allows your specialist to examine the interior of the colon. A colonoscopy may be performed to discover the cause of gastrointestinal symptoms, such as loose stool, bowl in the stool, abdominal pain, or abnormal x-ray results.

A colonoscopy might also be carried out on an asymptomatic patient at 45 years old or younger based on the person's history, to screen for colon and rectal cancer and polyps. As chief masters in digestive wellbeing, the board-certified gastroenterologists at a Specialists in Gastroenterology location in your community frequently carry out colonoscopy tests.

What are the benefits of a colonoscopy?

Colonoscopies are the strongest defense against the development of colon cancer, making it extremely important to have a colonoscopy as suggested by your gastroenterologist. Regular colon cancer screenings offer a great deal of benefits for your GI wellness and overall wellness. A few of the advantages of colonoscopy exams include:

  • May be a life-saving exam
  • Discovers initial signs of colorectal cancer
  • Provides the predominant testing option for colon and/or rectal cancer
  • Detects and excises abnormal polyps
  • Diagnoses IBD, diverticulosis, and additional GI concerns

Thanks to the latest technology, colonoscopy exams are executed more conveniently, with less discomfort, and more accurately than ever before.

You will receive instructions from your Specialists in Gastroenterology provider about the essential bowel preparation for your procedure. Most individuals are asked to drink only clear fluids the whole 24 hours prior to the procedure. There are many different options for laxatives to fully empty out the colon. It is crucial to observe the directions given to you by your provider. There might also be extra instructions regarding your prescriptions. In most situations, your medications will be continued as normal. Be that as it may, in certain circumstances, like in people on blood thinners (i.e., warfarin, Plavix®, Coumadin®, anti-inflammatories, aspirin) and in diabetics, unique orders may be specified. Patients will be instructed not to take anything by mouth following midnight excluding prescriptions.

You may be instructed to arrive at the endoscopy office an hour or an hour and a half before your test. This allows time to fill out documentation and prepare for the colonoscopy. You will be asked to change into a medical robe. An intravenous (IV) catheter will be inserted into your vein so that medication can be given. You will be attached to machines that will permit the provider and staff to check your heartbeat, blood pressure, electrocardiogram, breathing, and oxygen concentration during and after the colonoscopy.

When you reach the procedure room, you will be instructed to position yourself on your left side on the gurney. The IV sedation will be started. Tiny amounts are given to help ensure your safety and that the proper amount is given. Once a satisfactory amount of relaxation is achieved, the specialist will perform a rectal checkup. The colonoscope will then be softly introduced through the anus. The scope will be gingerly advanced across the colon to where the small intestine and colon join. A small quantity of air is fed through the scope and into the colon to allow the provider to assess the colon's lining. Any liquid remaining in the colon after the preparation can be cleaned and suctioned out by way of the scope.

Depending on the outcome of the exam, a few things could be done during the test, including biopsies, the withdrawal of tumors, and the repression of bleeding. At the end of the test, as much of the oxygen and leftover liquid as feasible is withdrawn out of the colon with the scope. Based on the findings, the exam takes about 15 – 30 minutes.

Once the procedure is finished, you will be escorted to the recovery room to be monitored while the IV drug starts to disappear. The amount of medication used for the duration of the test and your specific reaction to the medication will dictate how swiftly you will awaken, though most people are awake enough to be discharged within 45 – 60 minutes.

You will be advised NOT to drive for the remainder of the day after your colonoscopy with our St. Louis, MO team. As a result, you will need to have someone drive you home. You will also be directed not to go to work, sign important documents, or perform demanding actions for the remainder of the afternoon. Many people can eat and drink normally following their dismissal from the endoscopy unit; however, personalized orders about physical activity, eating, and medicines will be provided before you are discharged.

Upon conclusion of the exam, the specialist and/or support staff will go over the results of the exam with you. Most individuals will not recollect what is discussed after the exam due to the side effects of the sedation. It is recommended, if you can, to bring someone with you to whom the outcome can also be discussed. You could also return home with a written report. You will typically be informed of any biopsy results within one week.

To an extent, the other alternatives for this procedure will depend on the reason for necessitating the colonoscopy to begin with. In many situations, a colonoscopy is the most ideal approach to assess and treat abnormalities in the colon. There are other x-rays that can examine the colon, including a barium enema and a virtual CT scan. These are, though, only diagnostic procedures. Handling abnormalities will require a colonoscopy or surgery.

In general, a colonoscopy is a very routine exam. All in all, complications occur in less than 1% of patients. The majority of the complications are usually not fatal. Although, if a problem arises, it could involve hospitalization and surgery. Before the procedure, an acceptance form will be discussed with you by the nursing staff. Should any issues or problems appear, these can be addressed with your provider before starting the test.

Medical reactions related to IV medication can happen. These can involve but are not restricted to, allergic responses, trouble breathing, impacts on the circulatory system and blood pressure, and discomfort of the vein employed to administer the medication.

Bleeding can occur with biopsies and the extraction of tumors. Once more, substantial bleeding, which could require a blood transfusion or hospitalization, is extremely rare. Although, bleeding can occur during the exam or up to two weeks after the test if a tumor is eliminated.

Penetration or puncture of the intestine can occur. This may be identified at the time of the test, or it could not be noticeable until later in the day. In most instances, a perforation will necessitate surgery and a hospital stay. This is a rare complication, even when growths are withdrawn.

It is vital that you call your provider's office immediately if symptoms arise following the procedure, like worsening abdominal discomfort, bleeding, or elevated temperature.

Just as with any other exam, a colonoscopy is not perfect. There is a small, accepted danger that deformities, like growths and cancers, can be undetected during the test. It is essential to proceed to maintain appointments with your Specialists in Gastroenterology provider as instructed and inform them of any recent or constant symptoms.

By what age should you undergo a colonoscopy screening?

We suggest individuals who are at standard chance for colon cancer start scheduling their colon cancer screening when they turn 45 years old. In the event your odds for getting colon cancer are more likely or you are presenting distressing symptoms of colon cancer, your GI doctor could advise a colon cancer screening prior to that age.

How many years apart is it suggested you have a colonoscopy?

GI doctors suggest getting a colonoscopy screening about every ten years for patients who have average risk, who are in favorable health, and when they have colonoscopy test results that are normal. Following your colonoscopy, your GI doctor will inform you how many years apart you should schedule colon cancer screenings from here on out.

Is my colonoscopy going to be an uncomfortable procedure?

Sedation will be given to you ahead of your colonoscopy to maximize your comfort and relaxation while undergoing your exam. Based on the type of sedation given, most individuals will be in an extremely tranquil state or even become drowsy, and many experience virtually no memory of what happened. You can talk with your gastroenterologist about what you can experience during your consultation.

What’s the average recovery period for a colorectal exam?

Most of the time, it takes around a full 24 hours to recover after a colonoscopy screening, and a number of people feel well enough to start their normal routine the subsequent day. When colon or rectal polyps are found and removed, the recovery time will likely take about a week. It is expected to notice a bit of gastrointestinal symptoms following a colon cancer screening, including cramping and bloating. Our Specialists in Gastroenterology providers will give you more details on what is normal during the recovery period.

A colonoscopy is considered the “gold standard” of all testing approaches for colon cancer. Unlike many screening approaches, a colonoscopy enables the study of the entire colon. In addition to providing the most absolute inspection, it also permits the discovery of growths and their removal in just one procedure. For some different screening systems, the ability to extract tumors is not ready, and if the test returns positive for growths, you will probably require a colonoscopy.
