Diverticulosis and polyps of the large intestine. A necropsy study of hawaii japanese

Autopsy study of the colon of Hawaii Japanese indicates that, unlike native Japanese, diverticulosis and both adenomatous and hyperplastic polyps are very common in this population. This is consistent with observations that other populations show parallel trends for these conditions and large intestinal carcinoma. The adenomatous and hyperplastic polyps are more likely to occur together than either are likely to occur alone or in association with diverticulosis. Hyperplastic polyps are more likely to occur at anatomic sites which exhibit the highest frequency of cancer than do adenomatous polyps in this population.
