Bleeding is a feared complication of invasive procedures in patients with cirrhosis and significant coagulopathy (as defined by routine coagulation tests) and is used to justify preprocedure use of fresh frozen plasma (FFP) and/or platelets (PLT). Thromboelastography (TEG) provides a more comprehensive global coagulation assessment than routine tests (international normalized ratio [INR] and platelet count), and its use may avoid unnecessary blood product transfusion in patients with cirrhosis and significant coagulopathy (defined in this study as INR >1.8 and/or platelet count 40 min and/or PLT if maximum amplitude (MA) was <30 mm. All SOC patients received FFP and/or PLT per hospital guidelines. Endpoints were blood product use and bleeding complications. Baseline characteristics of the two groups were similar. Per protocol, all subjects in the SOC group received blood product transfusions versus 5 in the TEG group (100% vs. 16.7%; P < 0.0001). Sixteen SOC (53.3%) received FFP, 10 (33.3%) PLT, and 4 (13.3%) both FFP and PLT. In the TEG group, none received FFP alone (P < 0.0001 vs. SOC), 2 received PLT (6.7%; P = 0.009 vs. SOC), and 3 both FFP and PLT (not significant). Postprocedure bleeding occurred in only 1 patient (SOC group) after large‐volume paracentesis. Conclusions: In patients with cirrhosis and significant coagulopathy before invasive procedures, TEG‐guided transfusion strategy leads to a significantly lower use of blood products compared to SOC (transfusion guided by INR and platelet count), without an increase in bleeding complications. Remarkably, even in patients with significant coagulopathy, postprocedure bleeding was rare, indicating that TEG thresholds should be reevaluated. (Hepatology 2016;63:566–573)

Pancreatic metastases are rare, with a reported incidence varying from 1.6% to 11% in autopsy studies of patients with advanced malignancy. In clinical series, the frequency of pancreatic metastases ranges from 2% to 5% of all pancreatic malignant tumors. However, the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies. The epidemiology, clinical presentation, and treatment of pancreatic metastases from renal cell carcinoma are known from single-institution case reports and literature reviews. There is currently very limited experience with the surgical resection of isolated pancreatic metastasis, and the role of surgery in the management of these patients has not been clearly defined. In fact, for many years pancreatic resections were associated with high rates of morbidity and mortality, and metastatic disease to the pancreas was considered to be a terminal-stage condition. More recently, a significant reduction in the operative risk following major pancreatic surgery has been demonstrated, thus extending the indication for these operations to patients with metastatic disease.

As a consequence of continuous technical developments in liver surgery, laparoscopic liver resection (LLR) is increasingly performed worldwide. Between January 2004 and December 2011, 265 LLR were performed in 242 patients for various diseases. The experience of LLR is reported focusing on risk factors of conversion and their management. The overall conversion rate was 17/265 (6.4%), equally distributed over the period of the study. Statistically significant factors for conversion were found to be LLR of the postero-superior (P-S) segments (SI, SIVa; SVII; SVIII) (12.7% converted versus 2.5% non-converted groups, P = 0.01) and a major compared with a minor hepatectomy (15.2% vs. 4.6%, P = 0.02 respectively). A R0 resection was achieved in 93.2% of cases. According to Dindo's classification, complications were recorded as grade I (n = 20); grade II (6); grade III (11) and grade IV(1) events (total morbidity rate of 14%). Univariate analysis identified a major hepatectomy and resection involving P-S segments as prognostic factors for conversion whereas multivariate analysis identified the latter as an independent risk factor [P = 0.003, odds ratio (OR) = 5.9, 95% confidence interval (CI) = 1.8-18.8]. LLR can be safely performed with low overall morbidity. According to this experience and irrespective of the learning curve, resections of P-S segments were identified as an independent risk factor for conversion in LLR.

We designed a randomized trial to assess whether the early withdrawal of cyclosporine (CsA) followed by the initiation of everolimus (Evr) monotherapy in de novo liver transplantation (LT) patients would result in superior renal function compared to a CsA‐based immunosuppression protocol. All patients were treated with CsA for the first 10 days and then randomized to receive Evr in combination with CsA up to day 30, then either continued on Evr monotherapy (Evr group) or maintained on CsA with/without mycophenolate mofetil (CsA group) in case of chronic kidney disease (CKD). Seventy‐eight patients were randomized (Evr n = 52; CsA n = 26). The 1‐year freedom from efficacy failure in Evr group was 75% versus 69.2% in CsA group, p = 0.36. There was no statistically significant difference in patient survival between the two groups. Mean modification of diet in renal disease (MDRD) was significantly better in the Evr group at 12 months (87.7 ± 26.1 vs. 59.9 ± 12.6 mL/min; p < 0.001). The incidence of CKD stage ≥3 (estimated glomerular filtration rate <60 mL/min) was higher in the CsA group at 1 year (52.2% vs. 15.4%, p = 0.005). The results indicate that early withdrawal of CsA followed by Evr monotherapy in de novo LT patients is associated with an improvement in renal function, with a similar incidence of rejection and major complications.
