1. Myoglobinuria. Associated with Rhabdomyolysis. Urine color may be reddish-brown due to the presence of myoglobin. Positive for blood on dipstick exam, but no RBCs are seen on microscopic exam.
2. Bilious emesis. Associated with obstruction distal to the Sphincter of Oddi (location where bile enters digestive tract). The presence of bilious emesis excludes the presence of gastric obstruction. Bilious emesis in children is associated with malroation and volvulus and requres emergent intervention.
