BACKGROUND: Inadequate hemostasis during living donor liver transplantation (LDLT) is mainly due to coagulopathy but may also include fibrinolysis. The purpose of this study was to determine the incidence of fibrinolysis and assess its relevance to mortality in LDLT. METHODS: The incidence and prognosis of fibrinolysis were retrospectively studied in 76 patients who underwent LDLT between April 2010 and February 2013. Fibrinolysis was evaluated and defined by maximum lysis (ML) >15% within a 60-minute run time using thromboelastometry (ROTEM)...

RATIONALE: Currently, the treatment of hepatocellular carcinoma (HCC) associated with portal vein tumor thrombosis (PVTT) is a challenge. Percutaneous puncture endovascular placement of iodine-125 (I) seeds strand and stent is reported to treat HCC with tumor thrombus effectively. However, it is proved to be only suitable for the main portal vein (MPV) thrombus. PATIENT CONCERNS: A 42-year-old male patient was referred to our institution after experiencing right upper abdominal distention without abdominal pain, nausea, or vomiting for 2 weeks...

Hepatocellular carcinoma (HCC) is the sixth most common cause of death worldwide and the main cause of primary liver cancer. The principle problem of HCC is the poor prognosis, since advanced HCC reportedly has a median survival of only 9 months. The standard therapies are sorafenib and regorafenib, but the outcomes remain unclear. We report a 60-year-old man with advanced HCC with right adrenal gland metastasis and portal vein tumor thrombosis, who showed a complete response to multiple applications of an interdisciplinary therapy...

BACKGROUND: Pig islet xenotransplantation is a promising alternative to allogeneic transplantation. However, the wide immunologic barrier between pigs and primates limits the long-term survival of the graft. MD-3, a novel monoclonal antibody (mAb) that recognizes a particular epitope of human ICAM-1, can render T cells tolerant to a xenograft by arresting dendritic cell maturation. We report the long-term survival of adult wild-type pig islets and successful retransplantation in nonhuman primates using a protocol comprising induction with MD-3 mAb and maintenance with anti-CD154 mAb and sirolimus...

BACKGROUND: Biliary leakage remains a major cause of morbidity after liver resection. Previous prognostic studies of posthepatectomy biliary leakage (PHBL) lacked power, population homogeneity, and model validation. The present study aimed to develop a risk score for predicting severe PHBL. METHODS: In this multicentre observational study, patients who underwent liver resection without hepaticojejunostomy in one of nine tertiary centres between 2012 and 2015 were randomly assigned to a development or validation cohort in a 2 : 1 ratio...

Hydrogen sulfide, a toxic gas, at low concentrations is also a biological mediator in animals. In the colon, hydrogen sulfide is produced by intestinal tissues and gut sulfur bacteria. Gut-derived molecules undergo liver metabolism. Portal hypertension is one of the most common complications contributing to the high mortality in liver cirrhosis. We hypothesized that the colon-derived hydrogen sulfide may affect portal blood pressure. Sprague-Dawley rats were maintained either on tap water (controls) or on water solution of thioacetamide to produce liver cirrhosis (CRH-R)...

AIM: Graft size is a critical issue in living donor liver transplantation (LDLT). We hypothesized that too much portal flow could possibly be diverted into pre-existing collateral veins, alleviating small-for-size syndrome (SFSS) in LDLT. This study evaluated the impact of the preserved collateral veins in the outcomes of LDLT using a small-for-size graft (SFSG). METHODS: For patient safety, a graft-to-recipient weight ratio (GRWR) < 0.8% was strictly confined to patients with collateral veins (group A), and the patient group was compared in a 1:3 ratio to a matched group of patients with GRWR ≥ 0...

Case: A 64-year-old man with complaints of dyspnea and orthopnea secondary to a hepatic hydrothorax refractory to diuretic medication underwent the transjugular intrahepatic portosystemic shunt (TIPS) procedure to decrease the portal vein pressure. The TIPS procedure failed due to severe liver stiffness. Direct intrahepatic portocaval shunt (DIPS), a modified TIPS procedure that directly inserts a stent from the inferior vena cava to the portal vein, was successfully carried out. Outcome: The DIPS procedure significantly decreased the patient's pleural effusion and respiratory symptoms...

Portal vein thrombosis is a common complication in patients with cirrhosis. Anticoagulation involves a high risk of bleeding secondary to portal hypertension, so placing transjugular intrahepatic portosystemic shunts (TIPS) has become an alternative treatment for portal vein thrombosis. Three strategies for TIPS placement have been reported: 1) portal recanalization and conventional implantation of the TIPS through the jugular vein; 2) portal recanalization through percutaneous transhepatic/transsplenic) access; and (3) insertion of the TIPS between the suprahepatic vein and a periportal collateral vessel without portal recanalization...
