Background: In case of liver tumor, surgical resection is the therapeutic gold standard to increase patient survival. Among liver resections, right hepatectomy (RH) is defined as a major hepatectomy. The first aim of this study was to analyze the overall morbidity and mortality of patients undergoing RH, the second aim was to assess changes in both patients characteristic and surgical parameters and mortality rates in a single center institution., Materials: From 2001 to December 2015, 225 RH were performed in our center. We analyzed two time period: 2001-2007 and 2008-2015., Results: Ninety days post operative mortality was observed in 9 cases (4%) for the overall cohort. We observed a difference between the two groups in the use of Pringle Maneuver (p<0,001). This result is consistent in each major surgical indication: HCC (p=0,001), CLM (p=0,015) and BT (p=0,015). The estimated blood losses improved (p=0,028), particularly for the HCC cases (p=0,024). No difference was observed in terms of number of transfusions received between the two groups. Reduced length of stay was observed in the second group (p<0,001), more markedly for CLM cases (p=0,001)., Conclusion: To further improve the outcomes of RH, it is important to performed this major hepatectomy in hepatobiliary centers with an overall liver resection experience of at least few hundred cases., (Copyright © 2016 Editrice Gastroenterologica Italiana S.r.l.

Introduction: To report our experience on associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in patients with liver tumors., Methods: ALPPS is a surgical technique that allows hepatic resection after rapid liver hypertrophy., Results: Thirteen operations were performed: 8 for hepatocellular carcinoma (HCC) with liver cirrhosis (LC) and 5 for colorectal liver metastases (CRLM, n = 3) and cholangiocarcinoma (CC, n = 2) in normal livers (NL). Of the 11 men (85%), the median age was 60 years (range 36-74). Six (75%) HCC patients had BCLC stage C and 2 (25%) had BCLC stage B disease. The median % future liver remnant (FLR) volume increase was 71.7% in patients with LC and 64.8% in NL (p = 0.44). Twelve patients achieved a sufficient FLR growth after the first stage (92.3% efficacy). Four right trisectorectomies and 9 right hepatectomies were performed. All patients completed the second stage (100% feasibility). R0 resection was achieved in all cases. The 90-day mortality rate was 23.1% (12.5% for HCC patients with LC vs 40% for CRLM and CC patients with NL, p = 0.13). After the first stage the overall morbidity rates were 62.5% and 80% (p = 0.61), whereas after the second stage they were 87.5% and 80% in patients with LC and NL respectively (p = 0.99). At a median follow-up of 15 months (range 1-27), the median DFS was 9 months (CI95% 6-12), and the 1yr-DFS was 42%. The median survival was 25 months (CI95% 10-40), and the 1-yr overall survival was 74%., Conclusions: ALPPS induced a considerable and comparable FLR growth in HCC patients with liver cirrhosis and patients with CRLM and CC with normal liver parenchyma. HCC patients who underwent ALPPS had a high rate of macrovascular tumor involvement. A high rate of R0 resection is expected in properly selected patients., (Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.)
