The role of barium enema in colostomy closure in trauma patients

Recently, the routine use of barium enema preceding colostomy closure in trauma patients has been challenged. It has been argued that the nature of the injury should be apparent from the initial laparotomy and that the likelihood of finding an unsuspected colonic lesion in the young, previously healthy patients who constitute the majority of trauma patients is very small. We retrospectively reviewed 124 consecutive cases of patients who received colostomy takedowns for trauma. One hundred six of the patients had preoperative barium enema evaluation. 87.1 per cent of the examinations were negative, with a subsequent stoma closure complication rate of 20.4 per cent. Of the 13 positive barium enemas, 9 were falsely positive. These patients had a higher stoma closure complication rate of 39 per cent, a fact that could not be explained on the basis of their abnormal studies. The 18 patients who did not have barium enema performed did not have an increase in complications (17.6%). Barium enema failed to uncover unsuspected pertinent diagnoses, often added unnecessary delays and expense, and in no case changed the operative management. Contrast studies were found to be useful in defining anatomy in cases of known fistulas and when the takedowns were performed without the benefit of operative reports from the previous surgery.
