The rationale of practice for polypoid lesions of the colon.

Abstract

The rationale of practice must be based on the avoidance of adverse effects on the host attributable either directly or indirectly to polypoid lesions. The known adverse effects are summarized. The gross, morphological, and dynamic taxonomies of polypoid lesions are grouped to assist in predicting adverse effects known to occur within the human life span. Based on data from the vital statistics, autopsy studies, and clinical management reviews, a rationale of practice has been developed that is intended to keep adverse effects of polypoid lesions to a minimum with the avoidance of unnecessary cost, nonbeneficial clinical effort, and morbidity. The greatest potential lies in avoidance of polypoid lesions altogether. Consequently, etiology is also discussed in the search for knowledge that can be exploited to avoid the development of polypoid lesions.
