What Is Flexible Sigmoidoscopy?
A flexible sigmoidoscopy examines the rectum and lower portion of the colon using a thin, flexible camera. It's shorter than a full colonoscopy and is typically used for more targeted evaluation.
Why Is It Done? (Indications)
- Evaluating rectal bleeding
- Investigating lower abdominal or rectal symptoms
- Follow-up evaluation in specific clinical situations
How to Prepare
Step 1
A limited bowel prep, often an enema
Step 2
A light diet the day before, per instructions
Step 3
Sedation is optional and used less often than with colonoscopy
How It's Performed
The gastroenterologist guides the sigmoidoscope through the rectum and lower colon, examining the lining and taking biopsies if needed. The exam usually takes about 10 to 15 minutes.
What Happens After (Recovery)
Brief rest as sedation wears off
Resume normal diet and activity
Results reviewed with your doctor
Recovery is typically quick, especially without sedation, and most patients resume normal activities the same day.
Risks
- Mild bloating or cramping
- Rare bleeding if a biopsy is taken
- Very rare risk of perforation
