Might physicians be restricting access to liver transplantation for patients with alcoholic liver disease?

Background/aims: In France, the most common cause of cirrhosis is excessive alcohol consumption. Post-transplant survival rates in patients with alcoholic liver disease (ALD) are at least as good as those seen with other indications. However, fewer of these patients are found on the waiting list.

Increased expression of regulatory Tr1 cells in recurrent hepatitis C after liver transplantation.

Immune response failure during HCV infection has been associated with the activity of regulatory T cells. Hepatitis C-related cirrhosis is the main reason for liver transplantation. However, 80% of transplanted patients present an accelerated recurrence of the disease.

Pancreatic fistula after pancreaticoduodenectomy: the conservative treatment of choice.

Background: A pancreatic fistula (PF) is the most common complication after pancreaticoduodenectomy (PD), and its reported incidence varies from 2% to 28%. The aim of the present study was to analyse the treatment of a complicated PF comparing the surgical approach with conservative techniques.

Methods: From January 2000 through to August 2006, 121 patients were submitted for PD.

Significance of serum tumor markers carcinoembryonic antigen, CA 19-9, CA 125, and CA 15-3 in pre-orthotopic liver transplantation evaluation.

Tumor markers are elevated in a variety of nonneoplastic clinical situations, including liver diseases. Their sensitivity and specificity are lower for tumor screening in these cases. In this study, we investigated the frequency and significance of elevated tumor markers in the pre-orthotopic liver transplantation (OLT) evaluation among patients with end-stage liver disease who did not develop tumors after a long follow-up post-OLT.

APRI and FIB-4 Scores Are Useful After Liver Transplantation Independently of Etiology.

Noninvasive liver fibrosis scores are evaluated in hepatitis C virus-infected patients but are less known in liver transplant recipients. Fibrosis is a frequent, multifactorial event in these patients. This preliminary retrospective study reviewed the diagnostic performance of 3 simple scores for liver fibrosis in transplant patients: namely, APRI (aspartate aminotransferase to platelet ratio index), FORNS (platelets, gamma-glutamyltransferase, patient age, and cholesterol), and FIB-4 (patient age, aspartate aminotransferase, alanine aminotransferase, and platelets).

Liver recurrence of a subcutaneous temporal hemangiopericytoma: the index case.

Introduction: Hemangiopericytoma is an uncommon soft tissue vascular neoplasm. Intraperitoneal hemangiopericytomas such as primary or secondary liver location have been exceptionally described. Its natural history is mostly benign, but recurrences may occur and determining if these late-discovered tumors are distant metastases or synchronous slow and silent-growing locations is sometimes challenging.

Median arcuate ligament in orthotopic liver transplantation: relevance to arterial reconstruction.

Median arcuate ligament (MAL) syndrome results from luminal narrowing of the celiac artery by the insertion of the diaphragmatic muscle fibers or by fibrous bands of the celiac nervous plexus. In 10% to 50% of cases it is responsible for significant angiographic celiac trunk compression. In orthotopic liver transplantation (OLT), the presence of celiac compression by MAL is considered to be a risk factor for hepatic arterial thrombosis (HAT); it may lead to graft loss.

Cholecystocolonic fistula: facts and myths. A review of the 231 published cases.

Background: Cholecystocolonic fistula (CCF) is the second most common cholecystoenteric fistula and is often discovered intraoperatively, resulting in a challenging situation for the surgeon, who is forced to switch to a complex procedure, often in old, unfit patients. Management of this uncommon but possible finding is still ill defined.

Methods: An extensive review of 160 articles published from 1950 to 2006 concerning 231 cases of CCF was performed.

Complete hepatocellular carcinoma necrosis following sequential porto-arterial embolization.

Most patients with hepatocellular carcinoma (HCC) are not eligible for curative treatment, which is resection or transplantation. Two recent series have emphasized the potential benefits of preoperative arterio-portal embolization prior to surgical resection of such tumours. This preoperative strategy offers a better disease free survival rate and a higher rate of total tumor necrosis.

Portal venous gas following chemotherapy for colorectal cancer liver metastasis.

The standard of care for patients with colorectal liver metastases is a combination of chemotherapy and surgery. New chemotherapy regimens with biologic agents (cetuximab, bevacizumab) have been shown to increase tumor response rates. Although this might be beneficial and this is an expected endpoint, it should be noted that patients with synchronous colorectal and liver metastases are at risk of septic complications.

Laparoscopic division of a portosystemic shunt to treat chronic hepatic encephalopathy.

In the event of liver cirrhosis with severe portal hypertension, voluminous portosystemic shunt may lead to refractory encephalopathy. Obliteration of the shunt has been described as a satisfactory therapeutic solution, and reported procedures are mainly endovascular embolization and surgical shunt ligation through laparotomy. The former procedure is less invasive and seems to be as efficient.

Generation and modulation of hepatocellular carcinoma circulating cells: a new experimental model.

Background: To establish a new experimental model of human hepatocellular carcinoma by orthotopic implantation of tumoral cells with its subsequent removal, to generate and modulate circulating tumoral cells.

Materials And Methods: Three human hepatoma cell lines (HepG2, PLC/PRF, and Mahlavu) were orthotopically implanted under the Glisson's capsule of the left lateral lobe of the liver in a total of 56 non-obese diabetic/severe combined immunodeficiency mice. Tumor removal was performed 30 d after injection, and a laparotomy without tumor removal was done in control mice.

Interleukin-4 induces the activation and collagen production of cultured human intrahepatic fibroblasts via the STAT-6 pathway.

Interleukin-4 (IL-4) is overexpressed in liver grafts in a context of severe recurrent hepatitis C, during which the development of fibrosis is dramatically accelerated. In this study, we examined the effects of IL-4 on the activation and collagen production of cultured human intrahepatic (myo)fibroblasts (hIHFs), and investigated the underlying mechanisms. The myofibroblastic nature of cells was evaluated morphologically using activation markers (smooth muscle alpha-actin, vimentin and prolyl 4-hydroxylase).

Treatment of stage IVA hepatocellular carcinoma: should we reappraise the role of surgery?

Hypothesis: A subset of patients with stage IVA hepatocellular carcinoma (HCC) and preserved liver function may benefit from hepatic resection.

Design: Retrospective review of a prospectively collected database.

Setting: An academic tertiary care hepatobiliary unit.

Recurrent liver abscess secondary to ingested fish bone migration: report of a case.

Pyogenic liver abscess is an unusual cause of fever and abdominal pain, but it is potentially fatal. It is rarely caused by a local event, but rather by hematogenous dissemination or biliary tract disease. We report an uncommon case of liver abscess caused by the migration of a fish bone through the gastrointestinal wall.

Hepatocellular carcinoma developed on compensated cirrhosis: resection as a selection tool for liver transplantation.

The objective of this study was to evaluate the histological profile obtained from primary resection of hepatocellular carcinoma (HCC) as a selection tool for liver transplantation (LT). The natural history of HCC depends on its histological features. The clinical effectiveness of resection as a selection tool for salvage or de principe LT has been previously advocated.

Impact of localized congestion related to venous deprivation after hepatectomy.

Objective: We sought to assess the impact of localized venous congestion related to venous deprivation on liver function recovery and regeneration after hepatectomy, using the living donation model. Harvesting the middle hepatic vein (MHV) optimizes the venous drainage of right grafts but could lead to donor segment IV congestion.

Methods: In a series of 44 donors, 25 underwent right liver harvesting without the MHV and 19 with the MHV.

[A pancreatic pseudocyst associated with three simultaneous hemorragic complications].

The onset of secondary hemorrhagic complications with the development of pancreatic pseudocysts is rare but has a high mortality rate. Management of the hemorrhagic complications of pancreatic pseudocysts is surgical despite the contribution of arterial embolization. We report the observation of a 59-year-old patient who had presented an episode of acute pancreatitis 1 month before consulting for abdominal pain associated with an episode of melena.

Interleukin-4 induces human hepatocyte apoptosis through a Fas-independent pathway.

IL-4 is overexpressed in liver grafts during severe recurrent hepatitis C and rejection. Hepatocyte apoptosis is involved in both these phenomena. We therefore examined the proapoptotic effect of IL-4 on HepG2 cells and human hepatocytes in vitro, together with the underlying mechanisms.

Laparoscopic left lateral sectionectomy in living donors: safety and reproducibility of the technique in a single center.

Background Data And Objective: Left lateral sectionectomy for liver transplantation in children performed through laparoscopy is an innovative procedure that was developed by considering our acquired experience in both laparoscopic liver resection and graft harvesting in living donors. The main goal was to minimize donor morbidity while preserving the abdominal wall. Herein, we report the technical feasibility and reproducibility, and compared it with open liver resection (OLR).

[Air in the portal venous system: radiologic differential diagnosis and etiology-specific treatment].

Portal venous air is a rare but potentially grave radiologic sign. The routine use of abdominal CT and ultrasound allows the detection of minimal amounts of portal air, often at an asymptomatic stage. The first diagnosis to consider by both frequency and gravity is intestinal necrosis which carries a 75% mortality.
