Abstract

Background

The value of the hepatobiliary phase of gadoxetic acid disodium (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) in patients with hepatocellular carcinoma (HCC) has not been evaluated in detail.

Methods

Between 2008 and 2009, 61 patients with HCC within the Milan criteria underwent Gd-EOB-DTPA-enhanced MRI and hepatectomy. The tumor margin was determined preoperatively based on hepatobiliary phase images. Microscopic portal vein invasion (MPVI), intrahepatic metastasis (IM), and recurrence of HCC within 1 year after hepatectomy were evaluated in 24 patients with non-smooth margins at the periphery of the tumor and 37 patients with smooth margins.

Results

The number of patients with MPVI and IM of HCC was significantly higher among those with non-smooth margins (42 and 38%, respectively) than among those with smooth margins (3%; p = 0.0002 and 5%; p = 0.0042, respectively). A non-smooth margin was identified as a significant predictor of MPVI (odds ratio 18.814, p = 0.024) and IM (odds ratio 6.498, p = 0.036) of HCC on multivariate analysis. Furthermore, a non-smooth margin was identified as a significant predictor of recurrence within 1 year after hepatectomy (odds ratio 4.306, p = 0.04) on multivariate analysis.

Conclusions

A non-smooth tumor margin in the hepatobiliary phase of Gd-EOB-DTPA-enhanced MRI is useful to predict MPVI, IM, and early recurrence of HCC after hepatectomy.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
