The larger lumen of the rigid rectosigmoidoscope allows for a larger biopsy where pathology is in question. The cost associated with this examination is less than that for flexible sigmoidoscopy. The rigid rectosigmoidoscope can be purchased in a disposable model that performs well. It is important for the Emergency Physician who evaluates and treats problems related to the colon, rectum, and anus to be familiar with rigid rectosigmoidoscopy.
