We report this case of a 74-year-old man with altered anatomy secondary to Billroth-II surgery who underwent endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis and subsequently developed severe diffuse abdominal pain with drop in hemoglobin. Patient was found to have hemorrhagic shock requiring aggressive resuscitative measures. Patient was found to have large peripancreatic hematoma secondary to bleeding from gastroduodenal and superior pancreaticoduodenal artery pseudoaneurysms. Gastroduodenal artery aneurysm is the rarest of all the splanchnic artery aneurysms, and to our knowledge this is the only reported case of a gastroduodenal artery pseudoaneurysm complicating ERCP.
