Beyond the Rex: an innovative meso-intrahepatic portal vein bypass for late-onset extrahepatic portal vein occlusion after living donor liver transplantation.

The Meso-Rex bypass (MRB) is recognized as an effective treatment for portal hypertension secondary to extrahepatic portal vein occlusion (EHPVO) both in the pediatric and adult population, within or outside the context of liver transplantation. It is the preferred surgical treatment in most centers because not only does it addresses the portal hypertension, but also restores physiologic portal hepatopetal flow. However, the Rex recess, the landmark for this technique, may not be safely accessible in some patients.

Effective Invasiveness Recognition of Imbalanced Data by Semi-Automated Segmentations of Lung Nodules.

Over the past few decades, recognition of early lung cancers was researched for effective treatments. In early lung cancers, the invasiveness is an important factor for expected survival rates. Hence, how to effectively identify the invasiveness by computed tomography (CT) images became a hot topic in the field of biomedical science.

Multidisciplinary Taiwan consensus for the use of conventional TACE in hepatocellular carcinoma treatment.

Developed in early 1980s, transarterial chemoembolization (TACE) with Lipiodol was adopted globally after large-scale randomized control trials and meta-analyses proving its effectiveness were completed. Also known as "conventional TACE" (cTACE), TACE is currently the first-line treatment for patients with unresectable intermediate stage hepatocellular carcinoma (HCC) and delivers both ischemic and cytotoxic effects to targeted tumors. Although new technology and clinical studies have contributed to a more comprehensive understanding of when and how to apply this widely-adopted therapeutic modality, some of these new findings and techniques have yet to be incorporated into a guideline appropriate for Taiwan.

Portal Dynamics After Living Donor Liver Transplant in Pediatric Recipients: A 10-Year Follow-Up Retrospective Study.

Background: It may be difficult for pediatric patients to evaluate the impact of liver transplantation (LT) on splenomegaly due to the natural growth course. The long-term dynamics of portal vein (PV) size and PV flow after LT in pediatric patients are unclear. We aimed to evaluate the long-term transition of the splenic size, PV size, and PV flow velocity in pediatric patients who underwent successful living donor liver transplantation (LDLT) and survived >10 years.

Overexpression of miR-4669 Enhances Tumor Aggressiveness and Generates an Immunosuppressive Tumor Microenvironment in Hepatocellular Carcinoma: Its Clinical Value as a Predictive Biomarker.

Accumulating evidence suggests the involvement of tumor-derived exosomes in the development and recurrence of hepatocellular carcinoma (HCC). We previously identified miR-4669 as a highly expressed microRNA in circulating exosomes obtained from patients with post-transplant HCC recurrence. This study aimed to explore how overexpression of miR-4669 affects HCC development and recurrence.

Living donor liver transplantation for Barcelona clinic liver cancer (BCLC) intermediate-stage hepatocellular carcinoma.
