Laparoscopic approach for down-staging in hepatocellular carcinoma patients who are candidates for liver transplantation.

INTRODUCTION: The aim of this study was to assess the impact of laparoscopic thermoablation (LTA) and laparoscopic resection (LR) as neoadjuvant therapy before orthotopic liver transplantation (OLT) for hepatocellular carcinoma (HCC). METHODS: From June 2005 to November 2010, 50 consecutive patients affected by HCC with liver cirrhosis were treated with LTA under ultrasound guidance or LR. Of them, 10 patients (mean age, 58.3 ± 5.59 years; male:female, 8:2) underwent OLT. They were mostly Child-Pugh class A (80%). RESULTS: A LTA of 12 nodules was achieved in 7 patients and an LR of 3 HCC nodules in the other 3 subjects. The mean length of surgery was 163 minutes (range; 60-370). The mean hospital stay was 6.1 days. Transient mild postoperative liver failure was reported in 1 case. Complete tumor necrosis was observed in 10 thermoablated nodules (83.3%) via spiral computerized tomographic scan at 1 month after treatment; the resected patients showed absence of recurrence. All patients underwent OLT after a mean interval of 7 months. The histology of the native liver showed complete necrosis in 9/12 thermoablated nodules (75%); a recurrence at surgical site occurred in 1 patient in the resection group. CONCLUSIONS: Laparoscopic ultrasound can be used in potential OLTs candidates to accurately stage HCC in advanced cirrhosis with minimal morbidity. LTA and LR proved to be safe and effective techniques for HCC patients, representing a valid "bridge" to OLT.

Impact of Model for End-Stage Liver Disease score on transfusion rates in liver transplantation.

BACKGROUND: Liver transplantation (OLT) can entail a high risk of blood loss requiring transfusions, which increase morbidity and mortality. In recent years many efforts have been spent to improve the surgical and anesthetic management to decrease transfusion rates during OLT. Preoperative predictors for transfusion in OLT, remain uncertain. METHODS: We retrospectively reviewed the 219 OLT performed from 2005 to 2011 focusing on blood product (BP) transfusions. Statistical analysis sought the impact of transfusions on OLT outcomes to identify possible independent predictors of higher BP requirements. RESULTS: The 1- and 3-year survival rates were 86.6% and 76.45% for patients and 81.0% and 71.8% for grafts respectively. The mean intra- and perioperative red blood cell (RBC) transfusion rates were 12.3 ± 11.7 U and 15.5 ± 13.0 U respectively. A statistical analysis demonstrated a significant influence of BP transfusion on post-OLT complications and survivals. Multivariate logistic regression analysis showed the Model for End-Stage Liver Disease (MELD) score to be the only independent predictor of perioperative RBC transfusions. CONCLUSIONS: Our results confirmed the link between intra- and perioperative transfusions and outcome of OLT patients. MELD score resulted the only independent variable associated with increased perioperative RBC transfusions.
