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 I 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.
