Sigmoidoscopy is similar to colonoscopy, but is restricted to the last 2 feet of the colon and goes no farther. It is usually performed on younger patients who don’t clinically require a colonoscopy. Sigmoidoscopy provides a direct visualization of the lining of the colon and rectum. If anything unusual is detected – such as a polyp or inflamed tissue – a biopsy can be taken and sent for evaluation.
Sigmoidoscopy takes only 5-10 minutes to perform. During the procedure, you might feel pressure and slight cramping in your lower abdomen. This is temporary and resolves immediately after the procedure.Download Our Flexible Sigmoidoscopy Prep Instructions
