Indications for barium enema preceding colostomy closure in trauma patients.

The need for a barium enema (BE) preceding colostomy closure is controversial. In the process of evaluating the usefulness of BE before closure of colostomies performed for colorectal injuries, we reviewed our experience with 84 trauma patients who underwent BE before colostomy closure. Patients who had their colonic injuries repaired or diverted during the initial procedure did not benefit from the precolostomy closure contrast study. In this group of patients artifacts on BE had to be ruled out by endoscopy or repeat radiography in 9.5% of patients. Barium enema was found beneficial in evaluating colorectal injuries below the peritoneal reflection in one out of 20 patients. However, since the rectal injuries are not usually explored and repaired during the initial procedure, investigation by endoscopy and contrast studies may still be indicated preceding colostomy closure.
