[Importance of the dimensions and histologic nature of polyps of the colon in a comparison between double contrast enema and colonoscopy].

In 244 patients the results obtained by double contrast barium enema and endoscopy in the detection of small colonic polyps were compared. The results were evaluated by subdividing the polyps according to size. In order to define the endoscopic false positives percentage, controversial cases were re-examined with a second double contrast barium enema. The authors put forward a few considerations on the suitability of diagnosing small colonic polyps on the basis of their histologic nature.
