Determining the origin of an obscure massive and recurrent gastrointestinal (GI) bleeding is a challenging process in children. Sometimes it might be impossible to detect the exact location of bleeding with imaging tools so surgical exploration of abdomen is inevitable for diagnostic and also therapeutic purpose. And hence enterotomy introduced videoendoscopic examination (EIVE) may be the way for determining the exact intraluminal location of GI bleeding. This case report presents a patient who had intraluminal extensive patchy like jejunal gastric heterotopia (JGH) determined by EIVE. JGH starting 10th cm after Treitz ligament and extending 50 cm distally was excised totally. In postoperative follow up, recurrent and massive GI bleeding stopped and she did well in the second year of follow up without requiring transfusion.
