Reason for lower GI after having colonoscopy

Patient: Is there a good reason my son should have a lower GI xray. He recently had a colonoscopy, they found nothing except small infection and a stretched colon. He has encopresis

Symptoms: Encopresis

Doctor: Hello,Thank you for your query at AskTheDoctor.comI understand your concern.If your son already had a colonoscop y, then there is no need to get a lower gi x-ray or barium enema.Barium Enema especially is recommended before a colonoscopy to check for any small bowel lesions, as they are highly sensitive in picking up small bowel diseases.However, if a colonoscopy is already done, then there is no need to further get a barium enema done.They are normally picked over colonoscopy because they are comparatively cheaper.Hope this was helpful.Regards.
