What is the difference between flexible sigmoidoscopy and rigid sigmoidoscopy?

Do the different types of sigmoidoscopies differ in terms of procedure or the instruments used?

Healthcare Providers (1)

Flexible sigmoidoscopy is the most common type of scope used for this procedure as it is exactly that – flexible. It allows the doctor to guide the camera through the entire sigmoid colon, maneuvering around turns as they go. A rigid sigmoidoscope or anoscope as it is more commonly termed, is useful for certain colorectal surgical procedures (hemorrhoid banding, etc), but not useful for examining the entire sigmoid colon as it does not have the ability to sterr through the turns.
