Liver-directed surgery for NELM is associated with prolonged survival; however, the majority of patients will develop recurrent disease. Patients with hormonally functional hepatic metastasis without prior extrahepatic or synchronous disease derive the greatest survival benefit from surgical management.

Simultaneous colorectal and minor hepatic resections are safe and should be performed for most patients with SCRLM. Due to increased risk of severe morbidity, caution should be exercised before performing simultaneous colorectal and major hepatic resections.

This is the largest series comparing robotic to laparoscopic liver resections. Robotic and laparoscopic liver resection display similar safety and feasibility for hepatectomies. Although a greater proportion of robotic cases were completed in a totally minimally invasive manner, there were no significant benefits over laparoscopic techniques in operative outcomes.

Concomitant increasing incidences of hepatocellular carcinoma (HCC) and nonalcoholic steatohepatitis (NASH) suggest that a substantial proportion of HCC arises as a result of hepatocellular injury from NASH. The aim of this study was to determine differences in severity of liver dysfunction at HCC diagnosis and long-term survival outcomes between patients undergoing curative therapy for HCC in the background of NASH compared to hepatitis C virus (HCV) and/or alcoholic liver disease (ALD). Patient demographics and comorbidities, clinicopathologic data, and long-term outcomes among patients who underwent liver transplantation, hepatic resection, or radiofrequency ablation for HCC were reviewed. From 2000 to 2010, 303 patients underwent curative treatment of HCC; 52 (17.2%) and 162 (53.5%) patients had NASH and HCV and/or alcoholic liver disease. At HCC diagnosis, NASH patients were older (median age 65 versus 58 years), were more often female (48.1% versus 16.7%), more often had the metabolic syndrome (45.1% versus 14.8%), and had lower model for end-stage liver disease scores (median 9 versus 10) (all P < 0.05). NASH patients were less likely to have hepatic bridging fibrosis or cirrhosis (73.1% versus 93.8%; P < 0.001). After a median follow-up of 50 months after curative treatment, the most frequent cause of death was liver failure. Though there were no differences in recurrence-free survival after curative therapy (median, 60 versus 56 months; P 5 0.303), NASH patients had longer overall survival (OS) (median not reached versus 52 months; P 5 0.009) independent of other clinicopathologic factors and type of curative treatment. Conclusion: Patients with HCC in the setting of NASH have less severe liver dysfunction at HCC diagnosis and better OS after curative treatment compared to counterparts with HCV and/or alcoholic liver disease. (HEPATOLOGY 2012;55:1809-1819 C oncomitant increases in the incidence of hepatocellular carcinoma (HCC) and prevalence of nonalcoholic fatty liver disease (NAFLD) suggest that a substantial proportion of HCC arises as a result of hepatocellular injury from nonalcoholic steatohepatitis (NASH). As a result, HCC is the most rapidly increasing cause of cancer death in the United States.

In this multicenter analysis of patients with LCAs, risk of rupture correlated with increasing tumor size and recent hormone use. Rupture is associated with greater need for preoperative blood transfusion and major hepatic resection. These data suggest that patients with asymptomatic LCAs approaching 4 cm and those requiring hormonal therapy should undergo surgical therapy.

Background The purpose of this study was to compare the clinical and economic outcomes of robotic versus laparoscopic left lateral sectionectomy (LLS). Methods A retrospective analysis was made comparing robotic (n=11) and laparoscopic (n=18) LLS performed at the University of Pittsburgh Medical Center between January 2009 and July 2011. Demographic data, operative, and post-operative outcomes were collected. Results Demographic and tumor characteristics of robotic and laparoscopic LLS were similar. There were also no significant differences in operative outcomes including estimated blood loss and operating room time. Patients undergoing robotic LLS had more admissions to the ICU (46% vs. 6%), increased rate of minor complications (27% vs. 0%), and longer lengths of stay (4 vs. 3 days). There were no significant differences in major complication rates or 90-day mortality. The cost of robotic and laparoscopic LLS were not significantly different when only considering direct costs ($5,130 vs $4,408, p=0.401). However, robotic LLS costs were significantly greater when including indirect costs, which were estimated to be $1,423 per robotic case ($6 553 vs. $4 408, p=0.021). Discussion Robotic LLS yields slightly inferior clinical outcomes and increased cost compared to the laparoscopic approach.
