A flexible sigmoidoscopy is a diagnostic procedure that makes use of a long, thin, bendable scope that is positioned into the rectum and slowly advanced through the lower colon. This exam is somewhat limited in that not all of the colon will be examined. The pipe has a light and a camera on its end, which allows the doctor to closely inspect the lining of the colon. A sigmoidoscopy can be performed to diagnose the underlying cause of digestive problems, including:

  • Unusual x-ray findings
  • Bleeding from the rectum
  • Pain in the abdomen
  • Loose or watery stools

A flexible sigmoidoscopy might also be used to evaluate colon polyps as part of a colon cancer screening.
