A 67-year-old male presented with acute pancreatitis secondary to gallstones, also known as acute biliary pancreatitis, and subsequently developed gastric outlet obstruction and was transferred to our hospital. A gastro-jejunal feeding tube was placed and an open cholecystectomy was performed. The patient had a pancreatic drain placed for interval increase in pancreatic necrosis and then nearly exsanguinated from gastroduodenal artery pseudoaneurysm bleed. This was managed by coiling the gastroduodenal artery. The patient underwent a pancreatic necrosectomy with malencot drain placement and developed a post-operative upper gastrointestinal bleeding. An EGD showed diffuse gastritis, but no varices. And 18 days later the patient rebled, with the same diffuse gastritis. After further complications the patient elected to receive palliative care at a hospice facility. We are presenting this unusual case of diffuse, hemorrhagic gastritis after acute necrotizing pancreatitis.
