TY - CHAP M1 - Book, Section TI - Chapter 71. Rigid Rectosigmoidoscopy A1 - Reichman, Eric F. PY - 2013 T2 - Emergency Medicine Procedures, 2e AB - Rigid rectosigmoidoscopy has largely been replaced by the flexible sigmoidoscope for routine elective screening and diagnostic workups. The rigid rectosigmoidoscope is superior to the flexible sigmoidoscope in measuring distances accurately, examining an unprepared patient, and when trying to work within the bowel lumen, for example when removing foreign bodies. The larger lumen of the rigid rectosigmoidoscope allows for a larger biopsy of lesions 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 a physician who evaluates and treats problems related to the colon, rectum, and anus to be familiar with rigid rectosigmoidoscopy.
