Flexible Sigmoidoscopy


GI Health Specialists are experienced in Sigmoidoscopy - a procedure that examines the lower part of the gastrointestinal tract, including anal canal, rectum and sigmoid colon, using a thin flexible tube with its own inbuilt video camera, lens and light source called a colonoscope.

Why is it done?

Flexible sigmoidoscopy is performed to evaluate lower gastrointestinal symptoms including bleeding or rectal pain, without the need for thorough bowel preparation, although usually a cleansing enema is provided by staff at hospital immediately prior to the procedure being undertaken.

What is the benefit of a flexible sigmoidoscopy?

No formal preparation other than a cleansing enema is normally required for a flexible sigmoidoscopy and it can be performed whilst you are awake. However, the procedure may also be performed while you are sedated and asleep (a period of fasting for five hours prior to the procedure is required for sedation).

 Prior to the test please discuss any usual medications that you have with your doctor. If you do have a major condition – such as a heart or lung condition that requires special attention please let your specialist know.

If no sedation is required, you can be discharged quickly.

A period of observation is necessary if you have been sedated. 

Risks associated with Flexible Sigmoidoscopy 

Complications during flexible sigmoidoscopy are rare but relate to sedation if sedation is required as well as local irritation in the anorectal region.

 If any of your questions have not been answered here, please feel free discuss these with the doctor or nurse before the procedure begins.
