Diverticular disease of the colon in Korea.

This study is designed to determine the relative prevalence and characteristics of diverticular disease of the colon in Korea. We did a retrospective evaluation of 16,964 consecutive barium enemas performed at Koryo General Hospital between January 1971 and October 1986, and found 100 patients with diverticular disease of the colon. The results are as follows: 1) Colonic diverticula were found in 100 patients, and incidence of 0.59% in 16,964 consecutive barium enemas. The male to female ratio was 2.1:1. 2) Incidence rose with advancing age from 0.45% in the second decade to 2.5% in the seventh decade. 3) Patient age ranged from 19 to 77 years with more than 70% of the patients in the 5th, 6th and 7th decades. 4) The greater majority (81%) of the diverticular disease the right colon. 5) Fifty percent of the cases were classified as multiple diverticula. 6) The mean age of patients with right sided diverticula was 47.5 years and that of patients with left sided diverticula was 57.7 years. The mean age of single diverticular patients was 50.4 years and that of multiple diverticular patients was 48.4 year. 7) Associated diseases were hemorrhoids (18%), gall stones (12%) and previous appendectomy (11%). Among the 29 patients who had hemorrhoids and or a previous appendectomy, 28 of those had right sided diverticula.
