As colorectal polyps are precursors to colonic cancer, and an early detection and removal of colorectal polyps can positively affect the prognosis of colonic cancer (one of the leading causes of death by cancer), it is our goal to develo...
متن کاملA single method to document the size of endoscopically-excised colorectal polyps.

MATERIALS AND METHODS Twenty-five endoscopically-resected colorectal polyps were conventionally measured with a millimetre ruler and subsequently placed on a photocopier. Two measurements (one week apart) were made on the photocopies, between two marks limiting the largest dimens...
