Flexible Sigmoidoscopy

A flexible sigmoidoscopy is an exam that uses a thin, flexible tube (sigmoidoscope) to evaluate the lower part of the large intestine (colon). This test is typically utilized for patients who experience rectal bleeding, chronic diarrhea, abdominal pain, or a change in bowel habits. It can also be used to detect colon cancer.

What To Expect During the Procedure

Sigmoidoscopies are a minimally invasive procedure that can often be completed in 10 minutes. The colonoscope is inserted into your rectum and advanced into the sigmoid; the video shows up on a screen so the doctor may examine the lining of the sigmoid. Other instruments can be passed through a channel in the colonoscope to take biopsies or remove polyps. Sedatives will be administered during the exam to help you tolerate the procedure during which you will remain breathing on your own.

What To Expect After the Procedure

Once the procedure is completed, you will recover in the recovery area for 30 minutes. During that time, your vital signs will be captured, continuation of fluids will be administered, and your provider will come speak with you about your procedure findings. Once you are discharged, you are not to drive, consume alcohol, or make any important decisions for the following 12 hours.

Like all procedures, there are risks and side effects. Complications are rare, but can include a temporary feeling of bloating, bleeding after a biopsy or polyp removal, perforation, or a sedative reaction. You will be provided with a written summary of the procedure, discharge instructions explaining your recovery, and contact information for follow-up questions or concerns.
