Sonografische Funktionsuntersuchungen in der Gastroenterologie

Zusammenfassung

Die Sonografie stellt in der klinischen Routine der Diagnostik von gastroenterologischen Erkrankungen eine wichtige Untersuchungsmethode dar. Sie ist vorrangig ein morphologisches Untersuchungsverfahren. Da der Ultraschall aber Wandstrukturen von Hohlorganen wie der Gallenblase, des Pankreasganges und des gesamten Magen-Darm-Traktes hervorragend beurteilen und als Echtzeitmethode (real-time) die Bewegungsabläufe darstellen kann, eignet sich das Verfahren auch bestens zur Untersuchung und Erforschung funktioneller Abläufe bzw. von deren Störungen. Wir geben eine Übersicht über die Möglichkeiten der Funktionssonografie in den einzelnen Organbereichen. Die praktische Relevanz wird kritisch eingeschätzt.

Abstract

Ultrasonography has become increasingly important in the routine diagnostics of gastrointestinal diseases. It is first of all a morphological diagnostic method. As it not only assesses the wall structure of the gallbladder, the pancreatic duct and the whole gastrointestinal tract but also visualises motion sequences as a real-time-method, functional processes and their disruptions can especially be examined. The present authors give a review of the capacity of functional ultrasound in different anatomic zones and critically discuss its practical relevance.
