Perinealer (perianaler) Ultraschall (PNUS)

Zusammenfassung

Der perianale und perineale transkutane Ultraschall sind eine sehr effektive, aber viel zu selten angewandte Methode zur Darstellung von perianalen Entzündungsprozessen, z. B. im Rahmen eines Morbus Crohn und zum Staging von perianalen/perirektalen Tumoren. Regelhaft können mit dieser Untersuchungsmethode Fistelverläufe günstiger als von endorektal untersucht werden, da die Schallkopfführung dem häufig schrägen Fistelverlauf angepasst werden kann.

Abstract

Perianal and perineal ultrasound is an effective but rarely applied diagnostic modality. Transmural inflammation, fistula and abscesses in patients with inflammatory bowel disease can be delineated and perirectal tumours can be staged. The method is complementary to endorectal ultrasound. Also oblique transsphincteric fistula can be displayed in detail.

Schlüsselwörter
