[ Pathology of the colon associated with diverticulosis of the descending colon and the sigmoid. Instrumental clinical study ].

A retrospective survey was carried out on 87 patients with diverticulosis and 223 control subjects with a view to studying the incidence of colon pathology in association with diverticulosis of the colon. All subjects were given colonoscopies of the distal section of the colon. The survey revealed that the group of diverticulosis patients was, on average, older than the control group (72 v. 59 years). There was no significant difference in the performance or totality of the endoscopic examination. Subjective and objective symptomatology revealed no a priori evidence of pathology associated with diverticulosis. There was no statistically significant difference in the incidence of polyps, neoplasias, haemorrhoids or colon melanosis in the two groups.
