Model Predicting Survival in Intermediate-Stage HCC Patients Reclassified for TACE Based on the 2022 BCLC Criteria.

: The Barcelona Clinic Liver Cancer (BCLC) staging system for hepatocellular carcinoma (HCC) was updated in 2022 to refine patient stratification, particularly in patients with intermediate-stage (BCLC B) HCC. Although transarterial chemoembolization (TACE) remains a key treatment for these patients, there is no prognostic model for survival outcomes based on the pretreatment factors of patients who meet the updated 2022 BCLC indications for TACE. The aim of this study was to develop a pretreatment risk model predicting overall survival (OS) in patients with intermediate-stage HCC and reclassified as candidates for TACE according to the updated 2022 BCLC criteria.

A model for predicting poor survival in patients with cirrhosis undergoing portosystemic shunt embolization.

Background And Aim: Portosystemic shunt embolization (PSSE) is a promising treatment for hepatic encephalopathy (HEP) and gastric varix (GV) in cirrhotic patients with a spontaneous portosystemic shunt. However, PSSE may worsen portal hypertension causing hepatorenal syndrome, liver failure, and mortality. This study aimed to develop and validate a prognostic model that helps identify patients with a risk of poor short-term survival after PSSE.

After propensity score matching (PSM), initial tumor response rates, local tumor progression (LTP), and major complication rates were evaluated in the 32 pairs of PSM matched population.

Long-term outcomes of endoscopic ultrasound-guided gallbladder drainage versus in situ or ex situ percutaneous gallbladder drainage in real-world practice.

Objectives: Many studies showed better outcomes of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) when compared with percutaneous transhepatic gallbladder drainage (P-GBD) in which most tubes were left in situ. However, no studies have directly compared EUS-GBD with P-GBD after tube removal (ex situ). We compared the long-term outcomes of EUS-GBD and ex situ or in situ P-GBD in high surgical risk patients with acute cholecystitis.
