Pancreatic cancer presenting as bleeding gastric varices.

Given the extremely poor prognosis of pancreatic adenocarcinoma, early diagnosis is crucial; however, clinical signs and symptoms of the disease are neither sensitive nor specific. In the two cases described, previously undiagnosed pancreatic cancers initially presented with upper gastrointestinal tract hemorrhage. Endoscopic surveys to identify the origin of the bleeding revealed gastric varices secondarily attributed to splenic vein thrombosis. Upon further investigation, the splenic vein occlusions were found to be caused by pancreatic tumors. A review of the incidence, pathogenesis, diagnostic modalities, and implications of splenic vein occlusion is included.
