  • Internal hemorrhoids and a procedures to eradicate the hemorrhoids called “hemorrhoid banding” or “internal hemorrhoid band ligation.”
  • Colon polyps
  • Inflammatory bowel disease


How is Flexible Sigmoidoscopy different from Colonoscopy?

Flexible Sigmoidoscopy enables the visualization of the Sigmoid colon and rectum, whereas a Colonoscopy allows her to view the entire colon. Colonoscopy is the preferred screening method for cancers of the colon and rectum; however, a flex sig is adequate if hemorrhoid is the lesion of interest for performing the procedure.

It is possible that a laxative or an enema may also be required the morning of the procedure (Flexible Sigmoidoscopy).
A flexible Sigmoidoscopy typically takes about 20 minutes. It is not unusual for cramping or bloating to occur during the first hour after the procedure.
