title: The value of endoscopic ultrasound in localizing gastrinoma.
abstract: Correct localisation of pancreatic gastrinomas by endoscopic ultrasound seems to be possible in most cases. However, success rate in the duodenal wall is disappointing, even if the examination is performed under optimal circumstances by a very experienced examiner. Nevertheless, in certain conditions endoscopic ultrasound may yield important information, besides detection of the primary tumor for example about structures suspected to be metastases in the region of the gastrinoma triangle.
