Flexible sigmoidoscopy is a procedure that enables your physician to examine the lining of the rectum and a portion of your colon (large intestine). An instrument called a sigmoidoscope is used. It is a thin flexible tube with a light and camera at its tip. The instrument is advanced through the anus and into the rectum and colon. Tissue samples may be obtained during the procedure.

This procedure may be done in the office of Gastroenterology Consultants of Louisville or it may be done in the endoscopy suite. It may be done with or without sedation.

The procedure may take 15 to 30 minutes. During the procedure, you will be lying on your left side. You may feel pressure, mild cramping and bloating as the colon is filled with air and the sigmoidoscope is advanced through the rectum and colon.

Your physician will usually suggest a preparation prior to sigmoidoscopy. Preparations may vary based on your individual situation. Generally, the preparation consists of two Fleets enemas prior to the procedure. Sometimes a laxative such a magnesium citrate will be prescribed as well. You should not eat prior to the procedure. You may take your medications with water prior to the procedure. Be sure to tell your physician if you are taking blood thinners such as coumadin, aspirin or plavix.

After the procedure, you may feel bloated and pass the gas that was put into the colon. This should resolve quickly. If you did not receive sedation, you will be able to drive yourself home.

Flexible sigmoidoscopy is a very safe and well tolerated procedure. Complications are rare but may include perforation (tearing) the colon or bleeding from a biopsy site. If you have any symptoms such as severe abdominal pain, fever, chills or bleeding (more than 1/2 cup) you should contact your physician immediately.
