Safety and Efficacy of Microwave Ablation for Hepatocellular Carcinoma in the Setting of Transjugular Intrahepatic Portosystemic Shunt
AbstractThis retrospective analysis reviews five patients with transjugular intrahepatic portosystemic shunt (TIPS) who underwent percutaneous microwave ablation of hepatocellular carcinoma between January 2017 and September 2020. Mean tumor diameter was 2.0  cm (range 1.3–2.9 cm), and mean tumor distance from TIPS was 2.3 cm (range 1.5–3.3 cm). There were no major adverse events, and the TIPS patency was 100% post-ablation. The technical success rate was 100%, and the complete response rate was 100%. In this small study, percutaneous microwave ablation appears safe and effective for the tre...

Percutaneous Balloon Dilatation for Hepaticojejunostomy Stricture Following Paediatric Liver Transplantation: Long-Term Results of an Institutional “Three-Session” Protocol
ConclusionIn paediatric patients with benign anastomotic stricture of hepaticojejunostomy after liver transplantation, the “Three-session” percutaneous biliary balloon dilatation protocol is associated with a high rate of long-term success. In this limited series, the history of post-liver transplant major complication, defined as complications requiring a reintervention under general anaesthesia or advanced life su pport, seems to be an independent risk factor for stricture recurrence.
