Laboratory Studies

Laboratory investigations that may be warranted depend on the specific indication for stoma creation.


Imaging Studies

Imaging studies may be performed as part of the evaluation of the specific disease process and may include the following:

  • Plain radiography
  • Contrast enema examination (particularly before closure of stomas)
  • Computed tomography (CT)
  • Ultrasonography (US)

Before reversal of most ostomies in infants, performance of a distal contrast study should be considered for evaluation of the unused portion of the bowel. This is particularly important in babies treated for neonatal necrotizing enterocolitis with a diverting ostomy. Such patients may have an unrecognized distal intestinal stricture. Repair of the stricture is essential either before or during the procedure for reversal of the ostomy.



In selected cases where a colostomy or ileostomy was performed for intestinal obstruction of unclear etiology, biopsy of intestinal mucosa might be helpful for ruling out the possibility of Hirschsprung disease.
