Rigid Proctoscopy

This method can be diagnostic for colon and rectal pathology; however it has been replaced for routine cancer surveillance by endoscopy. This is still used by many surgeons for perioperative management of those patients with rectal pathology. It precisely establishes the distance between a rectal tumor and the anus. Used during surgery it can define the rectal stump that has retracted after a Hartman pouch procedure. Postoperatively this can be used to view and dilate a low coloproc-tostomy. It can be used to study pelvic outlet obstruction and demonstrate nonrelaxing pubis rectalis or rectal intussusception.
