A Study on the Shape of Colorectal Hyperplastic Polyps—Consideration of the Importance of the Location—

Sixty-nine hyperplastic polyps over 6mm in diameter were studied with respect to their size and location. Of these polyps, 47% in the rectum, 35% in the right colon, and 80% in the left colon were pedunculated. In other words, polyps with stalks were prevalent in the left colon. Horizontally growing tumors like hyperplastic polyps tended to be pedunculated depending on their location.
