Melena associated with gastric varices, in the setting of possible obstructing pancreatic adenocarcinoma, has been poorly documented as an initial presenting sign for pancreatic malignancy. Considering the late presentation of patients with pancreatic malignancy, it is important to consider all potential presenting symptoms for the early detection and treatment of pancreatic malignancy.

OBJECTIVES The utility of nasogastric aspiration and lavage in the emergency management of patients with melena or hematochezia without hematemesis is controversial. This evidence-based emergency medicine review evaluates the following question: does nasogastric aspiration and lavage in patients with melena or hematochezia and no hematemesis differentiate an upper from lower source of gastroint...

Endoscopy and hypotonic duodenography showed a submucosal tumor in the third part of the duodenum. Biopsy findings were suggestive of leiomyosarcoma, therefore pancreatoduodenectomy was performed. Hematoxylin-eosin staining of the resected specimen showed interlacing bundles of spindle-shape...
