Abstract

Introduction

Portal vein embolization (PVE) stimulates hypertrophy of the future liver remnant (FLR) and may improve the safety of extended hepatectomy. The efficacy of PVE was evaluated.

Methods

Records of 358 consecutive patients who underwent PVE before intended major hepatectomy at our institution from 1995 through 2012 were retrospectively reviewed.

Results

One hundred twelve patients (31.3 %) had right PVE alone; 235 (65.6 %) had right PVE plus segment IV embolization. The first-session PVE completion rate was 97.8 %. The PVE complication rate was 3.9 %. The median pre-PVE and post-PVE standardized FLRs were 19.5 % (interquartile range, 15.0–25.9) and 29.7 % (interquartile range, 22.5–38.2), respectively. Two hundred forty patients (67.0 %) underwent potentially curative resection. Sixty-two patients (25.8 %) had major post-hepatectomy complications; rates of postoperative hepatic insufficiency and 90-day liver-related mortality were 8.3 and 3.8 %, respectively. The proportion of patients with colorectal liver metastasis increased from 38.6 % before 2005 to 78.2 % in 2010–2012. Despite increased use of preoperative chemotherapy, postoperative hepatic insufficiency and 90-day liver-related mortality rates dropped from 10.6 and 4.1 %, respectively, before 2010 to 2.9 and 2.9 %, respectively, in 2010–2012.

Conclusions

PVE can be safely performed with minimal morbidity. Most patients can proceed to extended hepatectomy, which is associated with a minimal mortality rate.

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.
