Malignant biliary obstruction is commonly due to pancreatic carcinoma, cholangiocarcinoma and metastatic disease which are often inoperable at presentation and carry a poor prognosis. Percutaneous biliary drainage and stenting provides a safe and effective method of palliation in such patients, thereby improving their quality of life. It may also be an adjunct to surgical management by improving hepatic and, indirectly, renal function before resection of the tumor.

Trends and Disparities in Intrahepatic Cholangiocarcinoma-related Mortality in the United States from 1999 to 2020.

Purpose: Intrahepatic cholangiocarcinoma (ICC) arises from the epithelial cells of the bile ducts present inside the liver parenchyma and is associated with an overall poor prognosis due to advanced disease stage at the time of diagnosis. We used the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database to determine ICC-related mortality patterns in the United States from 1999 till 2020.
Methods: Age-adjusted mortality rates (AAMR) and crude mortality rates (CMR) were extracted from the CDC WONDER database.

Background: Liver transplantation is the standard therapy for end-stage liver disease in pediatric patients with biliary atresia (BA), congenital and metabolic conditions, and for an unresectable malignant tumor like hepatoblastoma (HB). BA is the leading indication for pediatric liver transplantation, while HB is the most common childhood liver cancer. Despite improved outcomes through advanced surgical techniques and novel immunosuppression, pediatric liver transplantation (pLT) is complicated by post-transplant infections.

This study aimed to evaluate the safety and efficacy of a 6-month placement of a fully covered self-expanding metallic stent for refractory benign biliary stricture.
Methods: Twenty-two patients with refractory benign biliary stricture (13 with chronic pancreatitis and 9 without) were recruited from five higher tertiary care centers.

Background: Circular RNAs (circRNAs) play a pivotal role in the development and advancement of various cancer types. However, the involvement of circ-PAN3 in hepatocellular carcinoma (HCC) is not well understood. To shed light on this, we conducted a comprehensive study through biochemistry, cell biology, molecular biology, and bioinformatics techniques to investigate the role of circ-PAN3 and its associated pathway in the progression of HCC.
