[Incidence of diverticular disease of the large bowel in non-chagasic and chagasic individuals with and without megacolon].
To study the frequency of association between two common colonic disease in our midst, chagasic megacolon and diverticular disease, we reviewed the barium enemas of 243 patients aged more than 35 years. Diverticula were detected in 22 (21.6%) of the 102 non-chagasic individuals, in 10 (35.7%) of 20 chagasics without megacolon, and in 14 (12.4%) of the 113 chagasics with megacolon. There was a statistically significant difference between the two chagasic groups, but not between each one of them and the non-chagasic group. The incidence of diverticula in the sigmoid colon of the non-chagasic group was significantly higher than in the sigmoid colon of the other two groups studied. Among the patients with association of megacolon and diverticular disease, the diverticula were always located in the nondilated portions of the large bowel. It is suggested that totally unfavorable conditions for the genesis and/or maintenance of diverticula exist in the dilated colon of chagasic patients.
