16 yo male presented with acute worsening diffuse abdominal pain, nausea, vomiting and minimal hematemesis for the past few days following an EGD for celiac disease.

The patient was managed expectantly with IV fluids, NG decompression, NPO and G-tube with improvement on follow up imaging and remained non-operative.
