Background: Postoperative liver failure consequent to insufficiency of remnant liver is a feared complication in patients who underwent extensive liver resections. The associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is a new approach for patient which tumor is previously considered unresectable.
Aim: To present ALPPS as an innovative surgical technique of two-staged hepatectomy for the treatment of patients with marginally resectable or initially nonresectable primary and metastatic liver tumors.
Technique: The procedure is performed in two steps. The first consists on ligation of the right portal vein branch. Subsequently, total or nearly total parenchyma dissection along the falciform ligament is performed, including the middle hepatic vein. A plastic bag is used to cover the right extended lobe, and the abdomen is drained and closed. The second one is performed after a computer tomography, six to 12 days interval. After laparotomy, the plastic bag is removed. The right artery, right bile duct and the right hepatic vein are divided. The extended right lobe is removed. Drain is placed at the resection surface, and the abdomen is closed.
Conclusion: The associating of liver partition and portal vein ligation can enable curative resection of liver metastasis in patients with lesions previously considered unresectable.

Background: The effectiveness and preferred reconstruction methods of pancreatectomy associated with vein resection (PAVR) for pancreatic cancer, especially for the extensive portal vein/superior mesenteric vein (PV/SMV) resections (more than 4 cm), are still subjects of debate. The aim of this study is to evaluate the safety and feasibility of PAVR by analyzing data from two large institutions from different regions.
Methods: From 2008 to 2018, we identified consecutive series of patients with pancreatic cancer who underwent PAVR at Karolinska University Hospital (KUH), Sweden, and Cancer Institute Hospital, Japanese Foundation of Cancer Research (JFCR), Japan.

Myeloproliferative neoplasms (MPNs) are clonal hematopoietic stem cell disorders commonly characterized by excessive production of blood cell lineages. The JAK2 V617F mutation plays a crucial role in the pathogenesis of these conditions, often leading to thrombotic complications. Here, we present the case of a 21-year-old man who presented with acute abdominal pain and was found to have portal vein thrombosis with splenomegaly.

Department of Radiology, Nanfang Hospital, Southern Medical University, Guangzhou 510151, Guangdong Province, China.
Background: Transjugular intrahepatic portosystemic shunt (TIPS) is an effective intervention for managing complications of portal hypertension, particularly acute variceal bleeding (AVB). While effective in reducing portal pressure and preventing rebleeding, TIPS is associated with a considerable risk of overt hepatic encephalopathy (OHE), a complication that significantly elevates mortality rates.
Aim: To develop a machine learning (ML) model to predict OHE occurrence post-TIPS in patients with AVB using a 5-year dataset.

In this article, we comment on the article by Cheng published in recently. Posthepatectomy liver failure (PHLF) remains a leading cause of hepatectomy-related mortality and can be evaluated according to liver reserve function. Liver stiffness (LS) measured by ultrasonic elastography and spleen area demonstrate a strong correlation with hepatic proliferation, fibrosis, and portal vein congestion, thus indirectly reflecting liver reserve function.
