Evaluation of Correlations between Underlying Disease and Port Complications

Abstract

Purpose: Evaluation of correlations between underlying disease and port complications.

Materials and Methods: Retrospective analysis of a data set of 3160 port systems, which had been interventionally implanted over a period of 10 years. Of these, 1393 were included in the final evaluation. The 7 most common underlying diseases and port-induced complications were considered. Port-related thrombotic events, port pocket infections as well as the port-induced sepsis were evaluated and classified as either early or late complications.

Results: In 1393 ports, 131 experienced complications. Of these, 22.1 % (n = 29) were early and 79.6 % (n = 102) late complications. The overall incidence rate of late complications was 0.253/1000 observed days. It differed significantly between the underlying diseases (p < 0.001) and was significantly lower in colon carcinoma when compared with pancreatic (p = 0.049), gastric (p = 0.012) and bronchial carcinoma (p = 0.042). The incidence rate of the port sepsis between the underlying diseases also differed significantly (p = 0.006) and had the highest rate in gastric and bronchial carcinoma. The occurrence of a thrombotic event also showed a significant difference in the incidence rates between the underlying diseases (p = 0.045) and was highest in pancreatic and gastric carcinoma.

Conclusion: There are significant differences in the incidences of complications between the underlying diseases. Knowledge about this can help to improve the port-care and to take specific preventive measures.

Key Points:

• significant differences in the incidences of port complications between underlying diseases

• incidence rate of late complications significantly lower in colon carcinoma compared to pancreatic, gastric and bronchial carcinoma

• highest incidence rate of port sepsis in gastric and bronchial carcinoma

• highest incidence rate of thrombotic events in pancreatic and gastric carcinoma

• studies on specific prophylactic measures required

Zusammenfassung

Ziel: Evaluation von Zusammenhängen zwischen Grunderkrankung und Portkomplikationen.

Material und Methode: Retrospektive Auswertung aus einem Gesamtdatensatz von 3160 Portsystemen, welche über einen Zeitraum von 10 Jahren interventionsradiologisch implantiert worden waren. Von diesen gingen 1393 in die endgültige Auswertung ein. Die 7 häufigsten Grunderkrankungen und portinduzierte Komplikationen wurden gegenübergestellt. Betrachtet wurden dabei portbedingte thrombotische Ereignisse, Porttascheninfektionen und die portinduzierte Sepsis, wobei Früh- und Spätkomplikationen unterschieden wurden.

Ergebnisse: Bei 1393 Ports traten 131 Komplikationen auf. Hiervon waren 22,1 % (n = 29) Früh- und 79,6 % (n = 102) Spätkomplikationen. Die Gesamtinzidenzrate der Spätkomplikationen betrug 0,253/1000 Beobachtungstage. Sie unterschied sich signifikant zwischen den einzelnen Grunderkrankungen (p < 0,001) und zeigte beim Kolonkarzinomen eine signifikant niedrigere Inzidenzrate gegenüber dem Pankreas- (p = 0,049), dem Magen- (p = 0,012) und dem Bronchialkarzinom (p = 0,042). Die Inzidenzrate der Portsepsis zwischen den Grunderkrankungen unterschied sich ebenfalls signifikant (p = 0,006) und war beim Magen- sowie Bronchialkarzinom am größten. Für das Auftreten eines thrombotischen Ereignisses zeigte sich ebenfalls ein signifikanter Unterschied der Inzidenzraten zwischen den einzelnen Grunderkrankungen (p = 0,045) und war dabei beim Pankreas- sowie Magenkarzinom am größten.

Schlussfolgerung: Es bestehen signifikante Unterschiede der Inzidenzen von Komplikationen zwischen den einzelnen Grunderkrankungen. Das Wissen hierüber kann helfen, die Portpflege zu verbessern und ggf. gezielte, präventive Maßnahmen zu ergreifen.
