Many authors at high-volume centers all over the world have reported improved outcomes of hilar cholangiocarcinoma by several aggressive surgical approaches such as extended hepatic resection, combined vascular resection, and hepatopancreaticoduodenectomy in recent years. There has been great progress in the surgical treatment of hilar cholangiocarcinoma with these previous efforts by aggressive hepatobiliary surgeons. In particular, surgical techniques, diagnostic modalities, and perioperative management have been remarkably improved as compared with before. Herein we report the surgical outcome for both hilar cholangiocarcinoma of Bismuth types II, III, and IV and intrahepatic cholangiocarcinoma involving the hepatic duct confluence during the recent 8-year period between 2001 and 2008 at our institution, the Department of General Surgery at Chiba University. From our recent experienced results, it can be concluded that the surgical strategy for hilar cholangiocarcinoma has been improved remarkably, and major surgical hepatectomy can be done with relative safety, and these aggressive surgical approaches, including combined vascular resection, may be warranted for the surgical treatment of hilar cholangiocarcinoma. However, the adoption of new innovative therapeutic approaches might be required for further improvement of surgical outcome of hilar cholangiocarcinoma.

Identifying predictive markers for survival in malignant biliary obstruction following percutaneous transhepatic biliary drainage.

University Hospital Southampton, Southampton General Hospital, Tremona Road, Southampton, Hampshire, SO16 6YD, UK. Electronic address:
Aim: Malignant biliary obstructive disease is commonly managed with percutaneous transhepatic biliary drainage (PTBD). Traditionally, outcomes are evaluated collectively despite substantial variability in the underlying aetiology and extent of disease. The purpose of this study was to investigate whether variability in survival could be explained by different underlying patient and disease factors.

Background And Aim: Stent placement for biliary drainage in patients with malignant hilar biliary obstruction (MHBO) has been a topic of long-standing debate, and the best approach remains controversial. Therefore, we aimed to evaluate the efficacy, safety, and removability of multi-hole fully covered self-expandable metal stents (MH-FCSEMSs) in a preclinical experiment using swine hilar bile duct obstruction (HBDO) models and to assess the feasibility and safety of stent placement in patients with MHBO.
Methods: Three minipigs underwent endoscopic retrograde cholangiopancreatography (ERCP)-guided endobiliary-radio frequency ablation (EB-RFA) to establish Bismuth type II hilar bile duct stenosis models.

Signet-ring cell carcinoma is a poorly differentiated adenocarcinoma with a high degree of malignancy, which rarely occurs in hilar bile duct. As far as I know, this is the third signet-ring cell carcinoma of hilar cholangiocarcinoma found so far. We used endoscopic ultrasound（EUS） and per-oral cholangioscopy（POCPS） to make a definite diagnosis.

Background: Perihilar cholangiocarcinoma presents unique challenges in perioperative management, requiring a comprehensive approach to optimize patient outcomes.
Aims: This case study focuses on the multidisciplinary management and innovative interventions performed in the perioperative care of a patient with hilar cholangiocarcinoma.
Methods: A comprehensive assessment and treatment strategy involving neoadjuvant therapy and interventional radiology techniques were implemented.

Managing acute coronary syndrome (ACS) in patients with a recent history of gastrointestinal bleeding presents a unique and challenging clinical dilemma, necessitating a careful balance between minimizing ischemic risk and avoiding potentially life-threatening rebleeding. Standard treatment for ACS typically involves dual antiplatelet therapy (DAPT) to prevent recurrent thrombotic events. However, in patients with recent gastrointestinal hemorrhage or significant anemia, these therapies may substantially increase the risk of life-threatening bleeding, complicating the decision-making process and often leading to conservative management strategies.
