title: [Value of endoscopic ultrasonography in the diagnosis of pancreatic and gastroduodenal endocrine tumors].
abstract: OBJECTIVE
  To present our experience in the localization of endocrine-gastroenteropancreatic tumors (EGPT) by endoscopic ultrasonography.
  
  
  METHODS
  Endoscopic ultrasonography was performed in 10 patients with 13 pancreatic tumors and four in the digestive tract.
  
  
  RESULTS
  Sensitivity and diagnostic efficacy were 69% and 70%, respectively. These values were greater than those observed by other image techniques. Also, additional diagnoses and other three tumors of less than 1 cm undiagnosed by ultrasonography (US), Computer Tomography (CT) and Magnetic Resonance (MR), were detected. Specificity was 80% because among five case-controls a false positive was found. With more experience and the possibility to find small tumors, USE should improve other image techniques in the diagnosis and localization of endocrine digestive tumors.
