Before the sigmoidoscopy, the doctor checks if anything is blocking the rectum by inserting a gloved finger into the anus and rectum (called a digital rectal exam, or DRE). The doctor inserts the sigmoidoscope through the anus and into the rectum and sigmoid colon.

What type of bowel preparation may be required before a sigmoidoscopy?
You will need to use an over-the-counter enema kit — typically a few hours before the exam — to empty your colon. You may be asked to take two enemas.
What is the primary reason for screening patient for the presence of fecal occult blood?
The fecal occult blood test (FOBT) is a lab test used to check stool samples for hidden (occult) blood. Occult blood in the stool may indicate colon cancer or polyps in the colon or rectum — though not all cancers or polyps bleed.
What is the purpose of performing a sigmoidoscopy?
A sigmoidoscopy is a diagnostic test used to check the sigmoid colon, which is the lower part of your colon or large intestine. This section of your colon is close to your rectum and anus. A sigmoidoscopy can help diagnose the following symptoms: Diarrhea.
Which of the following positions is used for the flexible fiber optic sigmoidoscopy?
1. The patient is placed in the left lateral decubitus position. A rectal examination is performed with the gloved finger, examining the prostate in the male patient and confirming anal patency.
Do you need an enema before a sigmoidoscopy?
A sigmoidoscopy requires two enemas before the procedure to clean out the lower part of the colon. If your travel time is more than 2 (two) hours, ask at the time of scheduling if you can do the prep (enemas) in the endoscopy suite.
When do you use a fleet enema before sigmoidoscopy?
Preparing for Flexible Sigmoidoscopy
Purchase two Fleet enemas at any pharmacy. These should be used the day of the exam. The first enema is given 2 hours before the scheduled exam. The second enema is given 1 hour before the scheduled exam.
What does it mean when your stool sample comes back positive?
Abnormal or Positive Results
An abnormal or positive FIT result means that there was blood in your stool at the time of the test. A colon polyp, a pre-cancerous polyp, or cancer can cause a positive stool test. With a positive test, there is a small chance that you have early-stage colorectal cancer.
What does it mean if you test positive for blood in stool?
Blood in your stool means there is bleeding in the digestive tract. The bleeding may be caused by a variety of conditions, including: Polyps, abnormal growths on the lining of the colon or rectum. Hemorrhoids, swollen veins in your anus or rectum.
What does positive occult stool mean?
A positive fecal occult blood test means that blood has been found in the stool. Your doctor will have to determine the source of the bleeding, either by doing a colonoscopy or by doing an examination to determine if the bleeding is coming from the stomach or small intestine.
Why have a sigmoidoscopy instead of a colonoscopy?
Sigmoidoscopy has fewer side effects, requires less bowel preparation, and poses a lower risk of bowel perforation (an uncommon event, when the screening instrument pokes a hole in the intestine) than colonoscopy, in which a similarly flexible, but longer, tube is used to view the entire colon.
What kind of sedation is used for flexible sigmoidoscopy?
Will I receive sedation? Flexible sigmoidoscopy is a short test and most people will remain comfortable without sedative drugs or pain killers. If you are particularly anxious about the test, we can provide intravenous sedation or Entonox gas.
Can a sigmoidoscopy detect diverticulitis?
By far the most common location for acute diverticulitis is the sigmoid colon, representing more than 85% of cases . For this reason, it is possible that a flexible sigmoidoscopy (FS) may be a viable alternative to full colonoscopy following acute uncomplicated sigmoid diverticulitis.
How long does a sigmoidoscopy enema take?
A flexible sigmoidoscopy procedure takes about 10-20 minutes. Patients will lie on their left side, knees drawn up, as the sigmoidoscope is inserted into the anus and a small amount of air is pushed through to inflate the colon.
How do you perform an enema before sigmoidoscopy?
Insert the nozzle into your anus (back passage) and squeeze in the liquid. Hold the liquid inside you for as long as possible, preferably 10 to 15 minutes. After five minutes (or as long as you have been able to hold the enema) go to the toilet and allow the enema liquid to flush away by opening your bowels as usual.
How far up does a sigmoidoscopy go?
This test uses a thin, flexible tube with a light and camera on one end. Your doctor places this end in the anus. Then they push it gently up through the rectum into the lower colon. They can see inside the colon through a small scope on the tube or on a video monitor.
Can you feel sigmoid colon?
The sigmoid is the lower third of your large intestine. It’s connected to your rectum, and it’s the part of your body where fecal matter stays until you go to the bathroom. If you have a sigmoid problem, you’re likely to feel pain in your lower abdomen.
Can sigmoidoscopy detect ulcerative colitis?
During a flexible sigmoidoscopy, a healthcare provider uses a scope to view the inside of the lower (sigmoid) colon and rectum. The procedure helps diagnose bowel problems, such as ulcerative colitis, an inflammatory bowel disease (IBD). It can also detect colon polyps that can become colon cancer.
How painful is a sigmoidoscopy?
How painful is a sigmoidoscopy? You may experience mild discomfort during the sigmoidoscopy, but you’re unlikely to need sedation or pain medications. During the exam, you may feel the urge to have a bowel movement as the scope is inserted through your anus and guided into your colon.
Can a sigmoidoscopy detect IBS?
A colonoscopy or sigmoidoscopy may be used to help diagnose irritable bowel syndrome (IBS). When a patient complains of symptoms such as diarrhea, constipation, bloating, abdominal pain and gas, a physician may order a colonoscopy or sigmoidoscopy to determine if the cause is IBS or another condition or abnormality.
What is a sigmoid polyp?
Hyperplastic polyps — Hyperplastic polyps are usually small, located in the end-portion of the colon (the rectum and sigmoid colon), have no potential to become malignant, and are not worrisome (figure 1).
