Abstract
Noncirrhotic portal hypertension (NCPH) accounts for approximately 10% of all cases of portal hypertension, with liver cirrhosis being the most common underlying etiology. One of the potential causes of NCPH is pancreatitis, due to the close anatomical relationship between the mesenteric vessels-particularly the splenic vein-and the pancreas, as well as the proinflammatory state associated with this condition. This case report describes a 61-year-old man with a history of necrotizing acute pancreatitis who developed spontaneous bacterial peritonitis secondary to prehepatic NCPH.
