• Detecting colorectal polyps or early-stage cancer
• Monitoring conditions like inflammatory bowel disease (IBD) or diverticulitis
• Follow-up after abnormal stool tests or imaging
For individuals aged 45 and above, especially those with a family history of colorectal cancer, sigmoidoscopy may be recommended every 5 years as part of routine screening.
Preparation is relatively simple compared to a full colonoscopy. It may include:
• Pre-procedure preparation includes abstaining from food and liquids for a few hours
• Laxatives or enemas to clear the lower bowel
• Adjusting medications if necessary
Your doctor will provide specific instructions tailored to your health status.
Sigmoidoscopy: A Key Procedure for Lower GI Health
Sigmoidoscopy is a minimally invasive procedure that allows doctors to examine the lower part of the large intestine—specifically the rectum and sigmoid colon. Whether used for routine screening or to investigate troubling symptoms, sigmoidoscopy plays a vital role in early detection and management of gastrointestinal conditions.
Sigmoidoscopy is a type of endoscopy that uses a thin, flexible tube called a sigmoidoscope, equipped with a light and camera, to inspect the inner lining of the rectum and sigmoid colon. The device is gently inserted through the anus, allowing real-time visualization of the lower bowel on a monitor.
There are two main types:
• Flexible Sigmoidoscopy: Uses a bendable tube and is the most commonly performed method.
• Rigid Sigmoidoscopy: Uses a straight, stiff tube and is now rarely used due to limited reach and comfort.
Doctors may recommend sigmoidoscopy for both diagnostic and screening purposes:
Diagnostic Uses
• Rectal bleeding or blood in stool
• Chronic diarrhea or constipation
• Abdominal or pelvic pain
• Unexplained weight loss
• Changes in bowel habits
The procedure typically takes 10 to 20 minutes and is performed in an outpatient setting. Here’s what happens:
• You’ll lie on your side on an exam table
• A lubricated sigmoidoscope is gently inserted through the anus
• The doctor evaluates the rectum and sigmoid colon to assess for abnormalities or signs of disease.
• If needed, biopsies or polyp removal may be performed.
Most patients remain awake, as sedation is usually not required. Mild discomfort or cramping may occur but is temporary.
Sigmoidoscopy is considered very safe. However, potential risks include:
• Minor bleeding (especially after biopsy)
• Infection
• Perforation of the colon (rare)
• Temporary bloating or discomfort
These risks are uncommon and are minimized by experienced medical teams and proper preparation.
