A flexible sigmoidoscopy is a diagnostic procedure used to examine the rectum and lower part of the colon using a thin, flexible tube equipped with a small camera. The procedure allows physicians to evaluate the lower digestive tract for signs of inflammation, polyps, bleeding, or other abnormalities.

Flexible sigmoidoscopy may be used to:

• Evaluate rectal bleeding

• Investigate changes in bowel habits

• Examine lower abdominal discomfort

• Detect inflammation or infection

• Identify colon polyps

• Monitor certain gastrointestinal conditions

• Screen portions of the lower colon

This procedure provides valuable diagnostic information while remaining less extensive than a full colonoscopy.

Your physician may recommend this procedure if you are experiencing:

• Rectal bleeding

• Persistent diarrhea or constipation

• Lower abdominal pain

• Changes in bowel movements

• Unexplained digestive symptoms

• Suspected inflammation of the colon

Early evaluation can help detect gastrointestinal conditions before they progress.

Before the Procedure

Patients receive preparation instructions prior to the appointment, which may include dietary guidelines or bowel preparation recommendations.

During the Procedure

The physician gently inserts the flexible scope into the rectum to examine the lower colon. The procedure is typically brief and may or may not require sedation depending on the patient’s needs and physician recommendations.

After the Procedure

Most patients can return home shortly after the procedure and resume normal activities the same day unless otherwise instructed.

If polyps or abnormal tissue are identified, small samples may be collected for additional testing.
