The emergence of colonic diverticulosis in urbanised Indians. A report of 23 cases.

Of a total of 969 barium enemas performed over a three year period, 23 (2.4%) showed colonic diverticulosis. The mean age of the patients was 58 years and the commonest site involved was the sigmoid colon. All the patients were urbanised and were obligatory vegetarians. Six (25%) of the patients had a complication of the disease and three of them required surgery. The possible relationship of the disease with socio-economic changes is highlighted.
