Peroral choledochoscope for anterograde bridging of biliary drainage via T-tube.

Postoperative biliary stricture after biliary surgery is a challenging condition. Biliary stent placement by endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) are the effective treatment for biliary stricture. We report a case of peroral choledochoscope was used for anterograde bridging of biliary drainage via T-tube.

An asparagine metabolism-based classification reveals the metabolic and immune heterogeneity of hepatocellular carcinoma.

Amino acid metabolism has been found to alter in cancers and contributes to malignant progression. However, the asparagine metabolism status and relevant mechanism in HCC were barely understood.
