Zusammenfassung
Die korrekte Lokalisation pankreatischer Gastrinome mittels Endosonographie ist in den meisten Fällen zuverlässig möglich, während die Erfolgsrate bei Gastrinomen in der Duodenalwand enttäuschend ist, selbst wenn die Untersuchung unter idealen Bedingungen durch einen erfahrenen Untersucher durchgeführt wird. Dennoch ist die endosonographische Diagnostik bedeutsam, da sich in speziellen Situationen wichtige Informationen liefern kann. Neben dem Nachweis des Primärtumors können andere relevante Strukturen identifiziert werden, bspw. Metastasen-suspekte Befunde im Bereich des Gastrinom-Dreiecks.
Summary
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.
