Prophylaxe und Therapie der Varizenblutung
Publikationsverlauf
Publikationsdatum:
14. Juni 2013 (online)
Endoskopisches Screening
-
Im Rahmen der Erstdiagnose einer Leberzirrhose sollte eine Indexgastroskopie zum Varizenscreening durchgeführt werden.
-
Die weiteren Screeningintervalle richten sich nach dem Schweregrad der Varizen und der Leberfunktion der Patienten.
Primärprophylaxe
-
In der Primärprophylaxe von Ösophagusvarizenblutungen sind nichtselektive Betablocker die Therapie der Wahl.
-
Bei bestehenden Risikofaktoren (Child-Pugh-Stadium B – C, Red Spots, Red Wale Signs) oder Unverträglichkeit für Betablocker kann alternativ die endoskopische Varizenligatur zum Einsatz kommen.
Akute Varizenblutung
-
Die Therapie der akuten Ösophagusvarizenblutung besteht aus Pharmakotherapie (Terlipressin) plus endoskopischer Therapie (1. Wahl: Ligaturtherapie; alternativ: Sklerotherapie mit n-Butyl-2-cyanoacrylat).
-
Als Interimslösung kann bei Versagen der endoskopischen Therapie ein selbstexpandierender Notfallblutungsstent eingebracht werden.
-
Als prophylaktische Medikation haben sich Antibiotika zur Reduktion der infektionsbedingten Mortalität und Laktulose zur Reduktion der hepatischen Enzephalopathie etabliert.
-
Bei Versagen der endoskopischen Therapie ist bei geeigneten Patienten als definitive Therapie die Anlage eines TIPS zu erwägen.
Sekundärprophylaxe
-
In der Sekundärprophylaxe von Ösophagusvarizen ist die Kombination NSBB plus Ligaturtherapie der Standard.
-
Nach der ersten Ligaturtherapie sollten bis zur kompletten Eradikation der Varizen PPI verabreicht werden.
Portal-hypertensive Gastropathie und GAVE
-
Aufgrund der unterschiedlichen Therapie der Blutung sind portal-hypertensive Gastropathie und GAVE streng zu unterscheiden.
-
Bei der portal-hypertensiven Gastropathie kommen NSBB und/oder TIPS zum Einsatz, bei GAVE endoskopisch-thermische Verfahren (z. B. APC) oder Bandligatur.
