Article Abstract

Purpose: To assess the efficacy and safety of transarterial chemoembolization (TACE) and portal vein radioactive seed insertion (RSI) combination in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT).

Material And Methods: The relevant databases were searched from the earliest to January 2021. The endpoints included treatment response, treatment side effects, and overall survival (OS).

Results: Nine studies were included in this meta-analysis. The pooled total response (TR,  = 0.55) and disease control (DC,  = 0.13) rates for HCC were similar between the two treatment groups. The pooled TR ( = 0.0004) and DC ( < 0.0001) rates for PVTT were both significantly higher in the TACE with portal vein RSI group than in the TACE without portal vein RSI group. The pooled HR for OS was significantly better in the TACE with portal vein RSI group than in the TACE without portal vein RSI group ( < 0.00001). The pooled rates of fever ( = 0.97), vomiting ( = 0.64), and myelosuppression ( = 0.65) were similar between the two groups.

Conclusion: Compared to traditional TACE, TACE combined with portal vein RSI can effectively prolong the patients' OS and decrease PVTT disease progression.

Background: Advanced-stage hepatocellular carcinoma (HCC) with high tumour burden and portal vein tumour thrombus (PVTT) is usually associated with poor survival outcomes. Rapid tumour control usually benefits long-term outcomes, which could be hardly achieved by solely systematic targeted and immunotherapy in current guidelines. Hepatic arterial infusion chemotherapy (HAIC) is reported as an effective intervention for rapid decrease of tumour burden.

Anatomical Risk Factors for Portal Vein Complications Following Right Hepatectomy in Living Donors.

Ann Surg

September 2025

Division of Hepatobiliary Surgery and Liver Transplantation, Department of Surgery, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea.

Objective: To determine the incidence, clinical outcomes, and anatomical risk factors of portal vein (PV)-related complications after right lobe donor hepatectomy (RLDH).

Summary Background Data: With the increase in living donor liver transplantation, large-scale studies on donor morbidity have been conducted to ensure donor safety. However, reports evaluating PV-related complications following right hepatectomy in living donors are lacking.

Background: Disturbances in lipid metabolism are usually associated with hyperlipidemia, which is commonly observed in donkeys with inappetence or anorexia. The diagnostic utility of ultrasound measurements of croup fat thickness (CFT) and relative liver echogenicity for lipomobilization in donkeys with fasting-induced hyperlipidemia was investigated. A prospective observational control study involving 25 donkeys was conducted, and the animals were randomly assigned to a fasting group (FG, n = 20) and a control group (CG, n = 5).

Aim Of The Study: To present a case series of four pediatric patients with PDPV, each with a different clinical presentation and surgical management.

Methods: We retrospectively reviewed four cases of PDPV managed at our institution. Two cases were associated with extrahepatic biliary atresia (EHBA) and discovered incidentally during surgery.

Gut-derived metabolites are essential for liver fibrogenesis. The aim of this study was to determine the alteration of indole-3-propionic acid (IPA), a crucial tryptophan metabolite, in liver fibrosis and delineate the roles of enterogenic IPA in fibrogenesis. In the present study, metabolomics assays focused on tryptophan metabolism were applied to explore the decreased levels of IPA in the feces and serum of cirrhotic patients, as well as in the feces and portal vein serum of fibrotic mice.
