AB  - GI  bleeding  varies  in  its  epidemiology  and  presentation  depending  on  whether  it  originates  from  the  upper  or  lower  GI  tract.  Upper  GI  (UGI)  bleeding  is  bleeding  proximal  to  the  ligament  of  Treitz,  whereas  lower  GI  (LGI)  bleeding  originates  distal  to  this  ligament.  A  recent  study  demonstrated  a  14%  increase  in  pediatric  GI  bleeding  associated  ED  visits  between  2006  (82/100,000  children)  and  2011  (94/100,000  children).1  In  this  sample,  20%  of  visits  were  for  UGI  bleeding,  30%  were  for  LGI  bleeding,  and  the  remainder  were  unspecified.  More  than  three-quarters  (81%)  of  the  patients  were  discharged  home  from  the  ED.
