Question 1

What is a colonoscopy?

Accepted Answer

Colonoscopy is a minimally invasive, painless endoscopic procedure that lets your doctor examine the lining of your large intestine (colon) for abnormalities. Under sedation, your doctor inserts a thin, flexible tube into your rectum and slowly

moves it through the entire colon length. This instrument called a colonoscope, has a camera and light source and allows your doctor to look at the lining of your colon and rectum.

Question 2

Why is colonoscopy recommended?

Accepted Answer

Many different methods can be used for colorectal cancer screening. You may have heard about alternatives to colonoscopy, such as stool tests and CT scans, also known as “virtual” colonoscopy. Although these tests have some benefits, colonoscopy is the single best screening test for colorectal cancer because it is still the only test that can (1) detect polyps which are pre-cancerous growths that may develop into colorectal cancer, and (2) directly prevent colorectal cancer by removing these polyps. No other test has these advantages. This is an important benefit for patients because once colorectal cancer has developed, it can no longer be removed with colonoscopy and requires more invasive treatments such as surgery and/or chemotherapy. Also, if a stool test or CT scan shows something abnormal within the colon, a colonoscopy would still be needed to investigate the abnormality further.

Question 3

What preparations are required before a
colonoscopy?

Accepted Answer

Before a colonoscopy, your doctor will explain how to change your diet and how to start your bowel preparation. You will also be instructed when to start fasting. You will generally be on a clear liquid diet the day before the exam. Your doctor will also instruct you to consume a solution that empties and cleans your colon before the exam. This is called bowel preparation, or bowel prep – this is the hardest part of the colonoscopy but also one of the most important! A clean and empty colon allows the physician to see more clearly; a dirty colon may result in an incomplete or partial examination and more difficulty in detecting polyps. Before your exam, most medications can be continued as usual. However, some medications can interfere with bowel preparation or the procedure's safety. Tell your doctor about any medications you are taking, particularly insulin or other diabetes medications, aspirin products, arthritis medications, blood thinners (such as warfarin, apixaban, rivaroxaban, heparin, etc.), and other drugs that interfere with clotting (such as clopidogrel (Plavix), ticagrelor, prasugrel, etc.). Over-the-counter medications and supplements should not be taken on the morning of the procedure. Tell your doctor about any medical conditions you have, such as heart, kidney, or lung disease. Also, be sure to mention any allergies you have to medications or latex. Follow your doctor’s instructions carefully to ensure a successful procedure.

Question 4

Why is it important to be screened for
colorectal cancer with a colonoscopy?

Accepted Answer

Colorectal cancer (cancer of the colon or rectum) is the second leading cause of cancer deaths in the United States. Every year, around 145,000 new cases of colorectal cancer are diagnosed. Roughly 52,000 people die from the disease each year. To put this into perspective, 1 in 22 men and 1 in 24 women will be diagnosed with colorectal cancer in their lifetime, and an American dies from colorectal cancer every 10 minutes. The sad part is that each of these tragedies could have been prevented by screening. It has been estimated that increased awareness and screening for colorectal cancer would save at least 30,000 lives each year. Most individuals are considered “average risk” for developing colorectal cancer during their life. For this group of people, screening for colorectal cancer is now recommended to start at age 45. African American patients, however, are at higher risk for developing colorectal cancer and should begin screening earlier. When individuals are at higher risk due to their family history or certain genetic conditions, screening should also begin sooner. Your doctor may also recommend a colonoscopy to evaluate for symptoms such as bleeding, abdominal pain, and chronic diarrhea. This is not a “screening colonoscopy” but is referred to as a “diagnostic colonoscopy” exam. Furthermore, a “surveillance colonoscopy” is an exam performed when you have had polyps removed in the past.

Question 5

What can I expect during a colonoscopy?

Accepted Answer

Immediately before the procedure, you may receive medications to help you relax, make you sleepy, and to minimize discomfort. You might feel abdominal pressure, bloating or cramping during the procedure. Depending on your doctor’s practice setting, the procedure may be done with certain types of anesthesia that allow you to be completely asleep for the entire length of the colonoscopy exam. You will lie on your left side or back during the exam. Your doctor will pass a long, flexible tube with a camera (a colonoscope) along the entire length of the large intestine (colon) and rectum to carefully examine the lining. The examination usually takes about 30 minutes. In rare cases, the doctor may be unable to move the colonoscope through the entire colon. If this happens, your doctor will tell you if any additional testing is necessary.

Question 6

What if the colonoscopy shows something abnormal?

Accepted Answer

During the exam, if your doctor sees something that needs more evaluation, a small instrument may be passed through the colonoscope to obtain a biopsy (tissue sample). Your doctor may find growths in the colon called polyps. Because most polyps are pre-cancerous (but still benign), they will most likely be removed during the examination. When a colonoscopy is performed to look for bleeding sites, the doctor might control bleeding by injecting medications, sealing off bleeding vessels with heat treatment (called cauterization), or applying small metal clips. These procedures usually do not cause any pain.

Question 7

What can I expect after a colonoscopy?

Accepted Answer

You will be sent home after the procedure when most of the effects of the medications have worn off. Someone must accompany you home from the procedure because of the medications used during the examination. You should not drive, operate machinery, or make legal decisions on the day of the procedure to ensure that the medication's effects have worn off. Even if you feel alert after the procedure, the medications can affect your judgment and reflexes for the rest of the day. Some patients experience mild discomfort, bloating, or pass gas because of the air introduced during the examination. Those symptoms usually resolve within a day. You can resume your usual diet unless you are instructed otherwise. Your doctor generally can inform you of the preliminary results of the procedure that day, but the results of some tests, including biopsies, may take several days to return.

Question 8

How often you need a colonoscopy depends on multiple factors:

Accepted Answer

How clean was your colon, and whether your doctor was able to examine everything.
How many pre-cancerous polyps you had that were removed.
The size of the largest polyp.
Whether any polyps had serious features such as early cancer. Based on these factors, your doctor will instruct you when to return for your next colonoscopy (i.e. 10 years, 5 years, 3 years, etc.).

Question 9

What are the possible complications of colonoscopy?

Accepted Answer

Colonoscopy is a common outpatient procedure. It does not require hospitalization. Complications from a colonoscopy are rare, but they can occur. Perforation (a hole or tear in the gastrointestinal tract lining), is very rare but can occur and may require emergency surgery. If a biopsy is taken or if a polyp is removed, the area may bleed, but it is usually minor. Bleeding usually stops on its own, but sometimes it requires treatment. Some patients might have a change in heart rate, blood pressure, or breathing from the medications. Although complications after a colonoscopy are uncommon, it is important to recognize their early signs. Contact your doctor immediately if you have a fever after the test or notice increasing abdominal pain, or bleeding, including black stools. If you have any concerns about a possible complication, it is always best to contact your doctor immediately.

Question 10

How Are Instruments Sterilized?

Accepted Answer

We take your safety very seriously. Our facility has the latest Olympus OER Pro Disinfector system, which is computer-controlled to ensure that all instruments are thoroughly cleaned and undergo high-level disinfection after each use. Only techniques known to kill all disease-causing bacteria and viruses, including hepatitis and AIDS, are employed in this process. All methods and sterilants are approved by the Food and Drug Administration (FDA), the American Society for Gastrointestinal Endoscopy (ASGE), the American Gastroenterological Association (AGA), the American College of Gastroenterology (ACG), and the Association for Professionals in Infection Control (APIC). Most accessories like biopsy forceps and polypectomy snares are single-use sterile items. Our dedicated staff cleans and sterilizes all other accessories using our two high-temperature steam autoclaves. Since 1996 when we opened Three Rivers Endoscopy Center, not one case of infection has been transmitted by colonoscopy. Our patients can be confident they are not risking infection during a colonoscopy examination.

Question 11

How about insurance?

Accepted Answer

We are dedicated to providing the best possible care and service to our patients and regard their understanding of financial responsibility as an essential element of quality care and treatment. An extremely important factor that our patients need to be aware of is that when a sedated procedure is performed, there are usually THREE or FOUR SEPARATE FEES charged:

A PROFESSIONAL FEE from the doctor performing the procedure. Charges for the Center for Digestive Health and Nutrition will include services provided by the physician. 
A FACILITY FEE from the surgical facility where the procedure was performed. Procedures may be performed at Heritage Valley Sewickley, Heritage Valley Kennedy, or Three Rivers Endoscopy Center. The facility fee includes fees for operating and recovery rooms, equipment, medications, nursing care, and standard supplies (as examples). 
An ANESTHESIA FEE from the organization providing these services. Perioperative Anesthesia Consultants, Inc. provides these services for Three Rivers Endoscopy Center.
