Flexible Sigmoidoscopyx

What preparation is required?

Your doctor will tell you what procedure preparation to use. Because the rectum and lower colon must be completely empty for the procedure to be accurate, it's important to follow your doctor's instructions carefully.

Should I continue my current medications?

Most medications can be continued as usual. Inform your doctor about medications that you're taking - particularly aspirin products or anticoagulants (blood thinners such as warfarin or heparin), or clopidogrel, as well as any allergies you have to medications.

What can I expect during flexible sigmoidoscopy?

Flexible sigmoidoscopy is usually well-tolerated. You might experience a feeling of pressure, bloating or cramping during the procedure. You will lie on your side while your doctor advances the sigmoidoscope through the rectum and colon. As your doctor withdraws the instrument, your doctor will carefully examine the lining of the intestine.

What happens after a flexible sigmoidoscopy?

Your doctor will explain the results to you when the procedure is done. You might feel bloating or some mild cramping because of the air that was passed into the colon during the examination. This will disappear quickly when you pass gas. You should be able to eat and resume your normal activities after leaving your procedure.

What are possible complications of flexible sigmoidoscopy?

Flexible sigmoidoscopy and biopsy are safe when performed by doctors who are specially trained and experienced in these endoscopic procedures. Complications are rare, but it's important for you to recognize early signs of possible complications. Contact your doctor if you notice severe abdominal pain, fevers and chills, or rectal bleeding. Note that rectal bleeding can occur several days after the exam.

What are the risks associated with this procedure

Risks include:

• Some pain or swelling in your lower abdomen if air was pumped into your intestines during the procedure (this will last until your body passes the extra air, shortly after the procedure)
• Damage to the colon (perforation) from the scope and possible infection, which may then require surgery for repair
• Bleeding inside the colon which may require surgery
• Respiratory depression and cardiac rhythm disturbance due to the administration of seditives can occur
