The efficacy of barium enema in the elderly.

Ninety-seven consecutive patients more than 70 years old (Group O) undergoing barium enema were studied to assess the usefulness of this investigation in their management. The patient's ability to co-operate was studied. Diagnostic yield was noted and compared to 70 consecutive patients less than 60 years old (Group Y). There was no correlation between mental test score, hearing or visual impairment and the patient's ability to co-operate. A significantly greater number of positive examinations was found in Group O (P less than 0.05). Following a positive examination, 55% of patients in Group O had a change in management. Surgical management was pursued in 14 patients, 11 of whom had a tumour.
