Intraluminal measurements of distance cephalad to the anal verge in the colorectal region of 40 consecutive adult patients were performed employing rigid and flexible proctosigmoidoscopic techniques. In 2/40 (5%) patients, the measurements were identical. In 32/40 (80%) patients, measurements employing a flexible proctosigmoidoscope exceeded measurements employing a rigid instrument by at least 3 cm. The observations have relevance in the context of assessments of adequate distal margins and preservation of anal continence in patients requiring colorectal surgery via transabdominal, transsacral, transperineal, and/or transanal routes.
