A biopsy study of gallstones in Nigerian igbos.
Within 6 years, approximately 7,500 surgical specimens were collected at a central laboratory serving the Igbos of Nigeria. Only 28 specimens were gallbladders. Gallstones were found in 5 females and 2 males. As in other developing communities in which the diet consists largely of traditional foods, pigment stones outnumbered cholesterol stones, the ratio being 6:1. The know complications were single instances of carcinoma and rupture of the gallbladder.
