Risk factors for biliary tract events during elective cholecystectomy waiting time after endoscopic retrograde cholangiopancreatography for choledocholithiasis.

Objectives: Endoscopic lithotripsy and elective cholecystectomy, followed by endoscopic retrograde cholangiopancreatography, are the first-line treatments for patients with common bile duct (CBD) stones (CBDS) and gallstones. However, this approach entails acute cholecystitis and recurrent cholangitis risk while patients await surgery. We aimed to identify acute cholecystitis and cholangitis risk factors during the waiting time for elective cholecystectomy.

Prospective study on planned biliary stent placement to treat small common bile duct stones.

Aims: Small common bile duct stones are known to occasionally clear spontaneously. This study aimed to prospectively assess the role of biliary stent placement in promoting the spontaneous clearance of small common bile duct stones.

Methods And Results: We analyzed patients presenting with common bile duct stones of ≤5 mm diameter between June 2020 and May 2022.

Diagnostic ability of pancreatic juice cytology via the minor papilla in patients with pancreas divisum.

Background And Study Aim: Endoscopic retrograde cholangiopancreatography (ERCP) is generally performed via the major papilla when evaluating patients with pancreatic disease. However, in patients with pancreas divisum (PD) or distortion of the main pancreatic duct, endoscopic retrograde pancreatography (ERP) should be performed via the minor papilla (MP). Our aim was to evaluate the efficacy and safety of endoscopic pancreatic juice cytology (PJC), performed via the MP, in patients with PD.

Nivolumab-induced liver injury with a steroid-refractory increase in biliary enzymes, in a patient with malignant mesothelioma: An autopsy case report.

This is the first autopsy report of hepatotoxicity from nivolumab immunotherapy for malignant mesothelioma. The increase in levels of biliary enzymes and randomly distributed endothelial damage were steroid-refractory, but second-line option was abandoned because of cachexia. Further discussions are needed regarding the customized management of immune-related toxicities.
