Purpose. Genetic polymorphisms of MICA and DEPDC5 have been reported to correlate with progression to hepatocellular carcinoma (HCC) in chronic hepatitis C patients. However, correlation of these genetic variants with HCC recurrence following hepatectomy has not yet been clarified. Methods. Ninety-six consecutive HCC patients who underwent hepatectomy, including 64 patients who were hepatitis C...

BACKGROUNDS Portal vein embolization (PVE) has been widely applied before extended hepatectomy; however, its clinical utility for patients with biliary cancer has not been fully addressed. METHODS Between 1991 and 2010, 494 patients with cholangiocarcinoma (n = 353) or gallbladder cancer (n = 141) underwent PVE before extended hepatectomy. PVE was performed by a transhepatic ipsilateral appro...

Changes in intercellular junctional morphology associated with rat liver regeneration were examined in a freeze-fracture study. After a two-thirds partial hepatectomy, both gap junctions and zonulae occludentes were drastically altered. Between 0 and 20 h after partial hepatectomy, the junctions appeared virtually unchanged. 28 h after partial hepatectomy, however, the large gap junctions usual...

BACKGROUND Clinical data regarding the influence of diabetes mellitus (DM) on the outcomes of patients undergoing hepatectomy are conflicting. To determine the impact of DM on the clinical outcomes of patients undergoing hepatectomy, we systematically reviewed published studies and carried out a meta-analysis. METHODS A systematic literature search of Pubmed, Sciencedirect, Web of Science, an...

Intra-abdominal infection (IAI) after hepatectomy is an important morbidity. Identification of risk factors that could be avoided in the perioperative period may reduce the prevalence of IAI after hepatectomy for hepatocelluar carcinoma (HCC).Between January 1995 and December 2009, all patients with HCC who underwent curative liver resection were evaluated retrospectively. Long-term outcomes we...

Gluconeogenesis and glycogenolysis are essential hepatic functions required for glucose homeostasis. During the initial phase of hepatic regeneration, the immediate-early genes (IEG) are rapidly expressed, and the IEG RL-1 encodes for glucose-6-phosphatase (G-6- Pase). G-6- Pase is a microsomal enzyme essential for gluconeogenesis and glycogenolysis. This study employs a partial-hepatectomy mod...

Transforming growth factor alpha (TGF alpha) stimulates DNA synthesis in adult rat hepatocytes, and plays a physiological role after partial hepatectomy by an autocrine mechanism. Somatostatin (SS-14) is a potent inhibitor of gastrointestinal function and inhibits proliferation in various cell types. We examined the proliferative effect of TGF alpha and the inhibitory effect of SS-14 on hepatoc...

Gastrin has been shown to be an important trophic hormone for the mucosa of the stomach and the proximal intestine. In the present study the effect of gastrin on liver regeneration after partial hepatectomy in rats was investigated. After partial hepatectomy a significant rise in the concentration of gastrin in portal venous blood was found six, 12, and 18 hours after 70% hepatectomy. The effec...

OBJECTIVE To evaluate the early and late results from laparoscopic hepatectomy procedures at a tertiary hospital in Brasília (DF), Brazil. METHODS The authors report on a series of 18 patients (11 women) who underwent laparoscopic hepatectomy performed by a single surgical team at Santa Lúcia Hospital, in Brasília, between June 2007 and December 2010. Age ranged from 21 to 71 years (median = ...

BACKGROUND The aim of this study was to characterize changes in outcome following hepatectomy for hepatocellular carcinoma (HCC) over a 30-year period. PATIENTS AND METHODS The clinical records of 372 patients who underwent a macroscopic curative hepatectomy for treatment of HCC between 1980 and 2009 were retrospectively examined. Patients were divided into two groups: an early group (1980-20...
