Magnetic resonance demonstrated siderotic regenerating nodules in a patient with hepatocellular carcinoma with accompanying liver cirrhosis. The siderosis disappeared when iron deficiency anemia developed in association with biliary hemorrhage. Magnetic resonance was sensitive enough to follow changes in the siderosis. The mechanism of iron deposition in regenerating nodules that accompanied liver cirrhosis did not seem to be related to the severity of the liver damage.

Biliary tract cancer (BTC), also known as cholangiocarcinoma, is a relatively rare type of cancer with a poor prognosis. Despite the combination of chemotherapy and advances in targeted therapy, which have potentially improved the prognosis of patients with BTC, research on outcomes remains inadequate. The present study thus analyzed the survival trends of patients with BTC.

Gallstone disease during pregnancy, or cholelithiasis, presents significant clinical challenges due to hormonal, anatomical, and metabolic changes. Progesterone therapy, commonly used in pregnancy for uterine bleeding, can exacerbate gallstone risk by reducing gallbladder motility and promoting cholesterol gallstone formation. This case report describes a 29-year-old pregnant woman with no prior gallbladder disease who developed multiple cholesterol gallstones during the third trimester while undergoing progesterone therapy for bleeding associated with a bicornuate uterus.

Precision medicine has emerged as a cornerstone in cancer treatment revolutionizing our approach across malignancies. Molecular profiling of biliary tract cancers (BTCs) has changed the treatment landscape positively by prolonging survival in an aggressively fatal malignancy in its advanced stages. The acquisition of tissue tumor DNA for genomic analysis in BTC is often anatomically challenging, limited by quantity and quality.

The presence of an aberrant right hepatic artery (a-RHA) could influence the oncological and postoperative outcomes after pancreaticoduodenectomy (PD). A comparative study was conducted, including patients who underwent PD with a-RHA or with normal RHA anatomy. The primary endpoints were R1 resection in all margins (pancreatic, anterior, posterior, superior mesenteric artery, and portal groove), overall survival (OS), and disease-free survival (DFS).

Objectives: This study evaluated the adequacy of using blood cultures alone for antibiotic therapy in mild-to-moderate acute cholangitis after adequate biliary drainage.
Methods: A prospective, multi-centre, non-inferiority, randomised trial was conducted from August 2015 to September 2023 across 12 tertiary hospitals in South Korea. Patients were randomly assigned 1:1 to groups.
