Die Bedeutung der Endosonografie im Staging des Rektumkarzinoms

Zusammenfassung

Für eine zeitgemäße Therapie des Rektumkarzinoms ist eine differenzierte präinterventionelle Diagnostik unerlässlich. Sie entscheidet über die Indikation zur neoadjuvanten Therapie und beeinflusst die Wahl des Operationsverfahrens. Der endoskopische Ultraschall ist etablierter Bestandteil dieser Diagnostik. Er zeichnet sich durch eine hohe Genauigkeit in der Bestimmung des T- und N-Stadiums aus. Neue Behandlungskonzepte und die rasante Entwicklung konkurrierender Methoden erfordern eine neue Standortbestimmung.

Abstract

Modern therapy of the rectal carcinoma is dependent on sophisticated preinterventional diagnostics, which is decisive with regard to the indication for neoadjuvant therapy and influences the decision concerning the method of surgery. Endoscopic ultrasound is an established part of this diagnostic process. It is characterised by a high accuracy in T and N staging. New therapeutic concepts and the rapid development of competing methods make a new assessment of its value necessary.
