Flexible sigmoidoscopy is a procedure that lets doctors look inside your
rectum and the lower part of your colon, known as the sigmoid and descending
colon. They use a flexible, narrow tube called a sigmoidoscope, which
has a light and camera at one end. This tool shows the lining of your
lower digestive tract on a monitor, helping doctors spot issues like inflammation,
ulcers, polyps, and cancer.
Why Do Doctors Use Flexible Sigmoidoscopy?
Doctors use flexible sigmoidoscopy to check out various symptoms and for
routine screenings. Common reasons include:
Unexplained Rectal Bleeding: To find the source of bleeding.
Changes in Bowel Habits: To evaluate persistent diarrhea or other unusual bowel movements.
Abdominal Pain: To investigate chronic or unexplained abdominal discomfort.
Unexplained Weight Loss: To determine potential underlying digestive issues.
Screening for Colon Cancer and Polyps: To catch early signs of colon and rectal cancer.
Flexible Sigmoidoscopy Procedure Overview
Positioning: You will lie on your left side on an examination table.
Scope Insertion: The doctor will gently insert the sigmoidoscope through your anus and
slowly advance it into your sigmoid colon. The scope inflates your colon
with air to provide a better view.
Examination: The camera sends images to a monitor, allowing the doctor to examine the
intestinal lining. You may be asked to change positions slightly to improve
visibility.
Tissue Removal: If polyps or abnormal tissues are found, they may be removed or biopsied
for further analysis.
After the Procedure
Recovery: You can usually go back to normal activities and diet right after the
procedure.
Mild Discomfort: You might feel mild cramps or bloating, which should go away soon.
When to Call Your Doctor: If you have severe pain, fever, constant bleeding, dizziness, or black
stools, call your doctor.
Results: Initial results may be available right after the procedure, while biopsy
results might take a few days. Your doctor will discuss the findings and
any necessary follow-up care.
Possible Complications
Flexible sigmoidoscopy is generally safe, but there are some risks. Potential
complications include:
Bleeding: Especially if a biopsy is taken or polyps are removed. This may happen
immediately or up to two weeks later.
Perforation: A rare but serious complication where a tear forms in the colon wall,
possibly needing surgical intervention.
Infection: Uncommon but possible.
When to Seek Immediate Care
Contact your doctor or seek immediate medical attention if you experience:
Severe abdominal pain
Fever
Continuous bleeding from your rectum
Dizziness or weakness
Black or tarry stools
General Preparation Instructions for Gastrointestinal Procedures
Each gastrointestinal procedure requires specific preparations to ensure
your safety and the success of the treatment. Here are some general guidelines:
Fasting: Avoid food and drinks, including water, for several hours, or more as
instructed by your healthcare provider.
Medications: You may need to adjust or pause certain medications. Follow the specific
directions given by your doctor.
Bowel Prep: Some procedures require clearing the intestines using either a liquid
solution or pills containing laxatives. Procedures like colonoscopy, flexible
sigmoidoscopy, and PillCam capsule endoscopy typically require this type
of preparation.
Please consult your doctor for detailed preparation instructions tailored
to your health needs and the specific procedure.
