The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. Due to the rapid advancements in the knowledge and available information, a consortium of members from countries across Asia Pacific, "APASL ACLF Research(More)
BACKGROUND Blood loss during elective liver resection is one of the main factors affecting the surgical outcome. Different parenchymal transection techniques have been suggested to decrease blood loss. OBJECTIVES To assess the benefits and risks of the different techniques of parenchymal transection during liver resections. SEARCH STRATEGY We searched(More)
BACKGROUND Different techniques of liver parenchymal transection have been described, including the finger fracture, sharp dissection, clamp-crush methods and, more recently, the Cavitron ultrasonic surgical aspirator (CUSA), the hydrojet and the radiofrequency dissection sealer (RFDS). This review assesses the benefits and risks associated with the various(More)
BACKGROUND Neuroendocrine tumours are tumours of cells which possess secretory granules and originate from the neuroectoderm. While liver resection is generally advocated in patients with resectable liver alone metastases, the management of patients with liver metastases, which cannot be completely resected, is controversial. OBJECTIVES To determine if(More)
BACKGROUND Vascular occlusion is used to reduce blood loss during liver resection surgery. The enzyme markers of liver injury are elevated if vascular occlusion is employed during liver resection. It is not clear whether ischaemic preconditioning prior to vascular occlusion has a protective effect during elective liver resections. OBJECTIVES To assess the(More)
BACKGROUND Veno-venous bypass is used to overcome the effects of clamping of the inferior vena cava and portal vein during liver transplanation. The routine use of veno-venous bypass is, however, controversial. OBJECTIVES To compare the benefits and harms of veno-venous bypass (irrespective of open or percutaneous technique; heparin-coated or no(More)
IgG4 cholangiopathy is a recently described distinctive type of hepatobiliary manifestation of IgG4-related disease. This is often misdiagnosed as a malignancy of the hepatobiliary system on clinical presentation and imaging. Accurate diagnosis is crucial for appropriate management. Histopathology provides crucial information and is characterized by(More)
BACKGROUND Piggy-back method of transplantation, which involves preservation of the recipient retrohepatic inferior vena cava, has been suggested as an alternative to the conventional method of liver transplantation, where the recipient retrohepatic inferior vena cava is resected. OBJECTIVES To compare the benefits and harms of piggy-back technique versus(More)
