Flexible Sigmoidoscopy
What is a Flexible Sigmoidoscopy?
Flexible sigmoidoscopy is an important screening procedure because of its ability to
detect early changes in the distal colon. The 60-cm flexible sigmoidoscope provides
excellent visualization with minimal discomfort to patients. Successful sigmoidoscopy requires
adequate patient preparation, proper equipment and an experienced examiner who can recognize both
normal and abnormal findings. Complications arising from sigmoidoscopy are rare, but patients
may experience some cramping, gas or watery stools.
Screening and primary preventive measures, including regular exercise and increased
dietary fiber intake, can lower the morbidity and mortality associated with colorectal cancer.
