INTRODUCTION: Anticoagulants are commonly indicated in cirrhotic patients due to high rate of (pro)thrombotic conditions. Low molecular weight heparin (LMWH) is safe in patients with esophageal varices. However, the safety of LMWH is unknown in patients undergoing prophylactic endoscopic variceal ligation (EVL). AIM: To define the 4-week risk of bleeding and death after prophylactic EVL in cirrhotic patients continuously treated with LMWH. METHODS: All EVLs performed at a tertiary Italian Center from 2009 to 2016 were retrospectively reviewed...

Collateral circulation secondary to liver cirrhosis may cause the development of large PSSs that may steal flow from the main portal circulation. It is important to identify these shunts prior to, or during the transplant surgery because they might cause an insufficient portal flow to the implanted graft. There are few reports of "steal flow syndrome" cases in pediatrics, even in biliary atresia patients that may have portal hypoplasia as an associated malformation. We present a 12-month-old female who received an uneventful LDLT from her mother, and the GRWR was 4...

BACKGROUND: Liver regeneration involves hyperplasia and hypertrophy of hepatic cells. The capacity of macroscopic liver tissue to regenerate in ectopic sites is unknown. We aim to develop a novel in vivo model of ectopic liver survivability and regeneration and assess its functionality. METHODS: Adult male Sprague-Dawley rats (n = 23) were divided into four groups: (1) single-stage (SS) group, wedge liver resection was performed, and the parenchyma was directly implanted into the omentum; (2) double-stage (DS) group, omentum pedicle was transposed over the left hepatic lobe followed by wedge liver resection along with omental flap; (3) Biogel + DS group, rats received intraperitoneal injection of inert polymer particles prior to DS; (4) Biogel + DS + portal vein ligation (PVL) group, Biogel + DS rats underwent subsequent PVL...

Post hepatectomy liver failure (PHLF) remains a significant cause of morbidity and mortality after major liver resection. Although the etiology of PHLF is multifactorial, an inadequate functional liver remnant (FLR) is felt to be the most important modifiable predictor of PHLF. Pre-operative evaluation of FLR function and volume is of paramount importance before proceeding with any major liver resection. Patients with inadequate or borderline FLR volume must be considered for volume optimization strategies such as portal vein embolization (PVE), two stage hepatectomy with portal vein ligation (PVL), Yttrium-90 radioembolization, and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)...

Patients with end-stage liver disease develop acute decompensation (AD) episodes, which become more frequent and might develop into acute-on-chronic liver failure (ACLF). However, it remains unknown how AD induces acceleration of liver disease. We hypothesized that remodeling of collagen type III plays a role in the acceleration of liver cirrhosis after AD and analyzed its formation (Pro-C3) and degradation (matrix metalloproteinase-degraded type III collagen [C3M]) markers in animal models and human disease...

Alveolar echinococcosis (AE) is a zoonotic disease that is caused by Echinococcus multilocularis that affects liver and a variety of organs and tissues. It differs from other echinococcal disease because it shows tumor like behavior in the affected organ and tissues. The treatment of choice is concomitant medical therapy and resection with negative margins. Nevertheless, resection with the intent of negative margins (R0) may lead to serious complications such as liver failure. In the present case report, we used Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy (ALPPS) procedure, which was defined in 2012 by Schnitzbauer et al, in a 28-year-old male patient to avoid complications of major liver resection in order to treat alveolar echinococcosis...

RATIONALE: Adequate future liver remnant (FLR) volume is often a concern for patients with hepatocellular carcinoma (HCC). Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure can rapidly lead to impressive growth of FLR. We describe the technique of an entirely laparoscopic radiofrequency-assisted liver partition with portal vein ligation for staged hepatectomy (RALPP) in a cirrhotic patient with HCC. PATIENT CONCERNS: A 33 year-old female cirrhotic patient with HCC in the right liver was indicated for RALPP as the predicted future liver remnant (FLR) was 21%...

Background: ALPPS (associating liver partition and portal vein ligation for staged hepatectomy) was introduced with the promise to reduce posthepatectomy liver failure (PHLF) in extended hepatectomies but has higher morbidity and mortality rates compared to conventional methods of volume enhancement. There are few studies of the incidence of PHLF after ALPPS and little information on how to avoid PHLF by functional testing. It remains unclear what causes the compromise in liver function despite rapid volume gain and if any of the modifications proposed reduce the incidence of PHLF...

BACKGROUND AND OBJECTIVES: Noncirrhotic nontumoral extrahepatic portal vein obstruction (EHPVO) is the second leading cause of portal hypertension (PHT) and is mainly related to prothrombotic disorders. Patients with EHPVO often require prolonged oral anticoagulation therapy (OAT) together with variceal band ligation (VBL) to prevent thrombosis recurrence and PHT-related bleeding, respectively. The benefit-risk balance of VBL in this context remains unknown. We aimed to assess upper gastrointestinal bleeding (UGB) risk and variceal eradication efficacy in EHPVO patients undergoing a VBL program without stopping OAT...
