Preamble This guideline has been approved by the American Association for the Study of Liver Diseases and represents the position of the Association. These recommendations provide a data-supported approach. They are based on the following: (1) formal review and analysis of the recentlypublished world literature on the topic (Medline search); (2) American(More)
OBJECTIVE To summarize the current world position on laparoscopic liver surgery. SUMMARY BACKGROUND DATA Multiple series have reported on the safety and efficacy of laparoscopic liver surgery. Small and medium sized procedures have become commonplace in many centers, while major laparoscopic liver resections have been performed with efficacy and safety(More)
OBJECTIVE To directly compare the oncologic outcomes of TLPD and OPD in the setting of pancreatic ductal adenocarcinoma. BACKGROUND Total laparoscopic pancreaticoduodenectomy (TLPD) has been demonstrated to be feasible and may have several potential advantages over open pancreaticoduodenectomy (OPD), including lower blood loss and shorter hospital stay.(More)
BACKGROUND Hepatic metastases from neuroendocrine tumors have a protracted natural history and are associated with endocrinopathies. Resection is indicated for symptom control. Previous reports have suggested improvement in survival for patients undergoing debulking procedures. STUDY DESIGN The records of all consecutive patients undergoing resection of(More)
PURPOSE MicroRNA (miRNA) is a new class of small, noncoding RNA. The purpose of this study was to determine if miRNAs are differentially expressed in hepatocellular carcinoma (HCC). EXPERIMENTAL DESIGN More than 200 precursor and mature miRNAs were profiled by real-time PCR in 43 and 28 pairs of HCC and adjacent benign liver, respectively, and in normal(More)
BACKGROUND AND AIMS The heparin-binding growth factors fibroblast growth factor (FGF) and hepatocyte growth factor (HGF) are potent mitogens for hepatocellular carcinomas (HCCs). Heparin-binding growth factor signaling is regulated by sulfation of cell-surface heparan sulfate proteoglycans (HSPGs). We hypothesized that hSulf1, a recently described(More)
BACKGROUND Metastatic neuroendocrine malignancies frequently cause incapacitating endocrinopathies, and metastases predominant in the liver. Hepatic resection of metastases from such tumors is attractive because the natural history of neuroendocrine tumors is protracted, clinical severity of the endocrinopathy correlates with tumor volume, and local and(More)
PURPOSE The current American Joint Committee on Cancer (AJCC) staging system for hepatocellular carcinoma (HCC) fails to stratify patients adequately with respect to prognosis. PATIENTS AND METHODS The ability of the currently proposed tumor (T) categories to effectively stratify the survival of 557 patients who underwent complete resection for HCC at(More)
From 1980 to 1989, 279 patients underwent pancreaticoduodenectomy at a single institution with a postoperative mortality of 4%. The aim of this study was to determine incidence, origin, and present management strategy of early complications following this operation. Significant morbidity occurred in 46% of the patients, including delayed gastric emptying(More)
