Diagnostic utility of contrast-enhanced ultrasound endoscopy in a case of hemosuccus pancreaticus

Hemosuccus pancreaticus is a rare condition characterized by bleeding from an intrapancreatic pseudocyst or ruptured peripancreatic aneurysm emptying from the main pancreatic duct (MPD) into the gastrointestinal tract via the duodenal papilla [1]. Contrast-enhanced computed tomography (CE-CT) is the primary diagnostic modality for hemosuccus pancreaticus. However, the indication for CE-CT should be carefully evaluated in individuals with renal dysfunction or an allergy to contrast media [2]. We describe a case where contrast-enhanced endoscopic ultrasound (CE-EUS) was useful in diagnosing hemosuccus pancreaticus ([Video 1]).
