BACKGROUND: Perioperative allogeneic blood transfusion is associated with poor oncologic outcomes in multiple malignancies. The effect of blood transfusion on recurrence and survival in distal cholangiocarcinoma (DCC) is not known. METHODS: All patients with DCC who underwent curative-intent pancreaticoduodenectomy at 10 institutions from 2000 to 2015 were included. Primary outcomes were recurrence-free (RFS) and overall survival (OS). RESULTS: Among 314 patients with DCC, 191 (61%) underwent curative-intent pancreaticoduodenectomy...

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) was introduced more than four decades ago as a diagnostic tool for biliary and pancreatic diseases. Currently, ERCP is mainly used as a therapeutic approach to relieve biliary or pancreatic duct obstruction. Clinical practice has been based on a few large reports and some randomized controlled trials. These data are valuable and important, but the external validity of these reports is limited. Implementation into routine practice should be balanced with the knowledge that these studies were conducted under very specific circumstances...

Cholangiocarcinoma (CCA) is a deadly cancer of the biliary epithelium with limited therapeutic options. It is a heterogeneous group of cancer that could develop at any level from the biliary tree and is currently classified into intrahepatic, perihilar and distal based on its anatomical location. With incidence and mortality rates currently increasing, it is now the second most common type of primary liver cancer and represents up to 3% of all gastrointestinal malignancies. High-throughput genomics and epigenomics have greatly increased our understanding of CCA underlying biology, however its pathogenesis remains largely unknown...

BACKGROUND AND AIMS: Catheter-based endobiliary radiofrequency ablation (RFA) is an endoscopic local treatment for patients with malignant biliary stricture (MBS). However, excessive heating of the bile duct by the current RFA system can induce serious complications. Recently, a new RFA system with automatic temperature control was developed. In the present study, we examined the safety of the new RFA system in patients undergoing endobiliary RFA for extrahepatic MBS. METHODS: This prospective, multicenter study enrolled patients with unresectable or inoperable extrahepatic (>2 cm from the hilum) MBS...

The rising incidence of cholangiocarcinoma (CCA) coupled with a low 5-year survival rate that remains below 10% delineates the urgent need for more effective treatment strategies. Although several recent studies provided detailed information on the genetic landscape of this fatal malignancy, versatile model systems to functionally dissect the immediate clinical relevance of the identified genetic alterations are still missing. To enhance our understanding of CCA pathophysiology and facilitate rapid functional annotation of putative CCA driver and tumor maintenance genes, we developed a tractable murine CCA model by combining the cyclization recombination (Cre)-lox system, RNA interference, and clustered regularly interspaced short palindromic repeats/CRISPR associated protein 9 (CRISPR/Cas9) technology with liver organoids, followed by subsequent transplantation into immunocompetent, syngeneic mice...

Extramural consultation for challenging pathology cases is an important part of patient care. The specific reasons why liver cases are submitted in consultation are poorly understood. To study patterns in extramural consultation, data were gathered from 1360 liver/GI/pancreatobiliary consults submitted to 7 academic centers. Liver cases comprised 40% of consults and are the focus of this paper. They were submitted for questions on medical (61%) and tumor pathology (39%). A preliminary diagnosis was provided by the referring pathologist in 65% of cases...

INTRODUCTION: Cholangiocarcinoma (CCA), one of the most common primary biliary malignant tumors with high mortality. MIR22HG has been reported to act as a tumor-suppressor gene in several types of cancers. But, the role and molecular regulatory mechanism of MIR22HG in CCA are still unclear. AIM: The aim of the present study is to investigate the role and the underlying mechanism of MIR22HG in CCA. RESULTS: In this study, we firstly found that MIR22HG expression was significantly downregulated in CCA tissues and cell lines...

AIMS: Increasing evidence has demonstrated that serum soluble B7H3(sB7-H3) is a useful tumor marker for cancer diagnosis and prognostic evaluations. Whether sB7-H3 expressed in the bile is related to the progression of malignant biliary strictures must be clarified. METHODS: Bile sB7-H3 was obtained via endoscopic retrograde cholangiopancreatography (ERCP) from 323 patients suspected to have malignant biliary strictures and was detected using a B7H3 ELISA kit. Diagnostic value was compared among bile sB7-H3, CA19-9, CA12-5, and CEA and ERCP-based cytological/tissue examination...

Most patients with perihilar cholangiocarcinoma present with surgically unresectable disease owing to the insidious nature of this malignancy. Relief of malignant perihilar biliary obstruction is a key aspect of cholangiocarcinoma. Although palliative stenting using uncovered metal stents has been advocated in patients with unresectable malignant perihilar biliary strictures, several endoscopic retrograde cholangiopancreatography-guided ablative modalities have emerged. Palliative photodynamic therapy, radiofrequency ablation, and intraluminal brachytherapy have been associated with improved stent patency and survival, although the ideal treatment approach remains unclear...

Endoscopic retrograde cholangiopancreatography is the preferred procedure for biliary drainage in benign and malignant obstructions. Endoscopic ultrasound-guided biliary drainage is an emerging technique for when endoscopic retrograde cholangiopancreatography fails. It is a highly versatile procedure with several options of access point, stent direction, and drainage route. Based on the current literature, the cumulative success rate is 88% to 93%, with an overall complication rate of 13% to 20%. Endoscopic ultrasound-guided biliary drainage seems to be an effective and valuable alternative technique after failed endoscopic retrograde cholangiopancreatography when performed by highly skilled endoscopists...

Benign and malignant biliary strictures are common indications for endoscopic retrograde cholangiopancreatography. Diagnosis involves high-quality cross-sectional imaging and cholangiography with various endoscopic sampling techniques. Treatment options include placement of plastic biliary stents and self-expanding metal stents, which differ in patency duration and cost effectiveness. Whether the etiology is benign or malignant, a multidisciplinary strategy should be implemented. This article will discuss general principles of biliary stenting in both benign and malignant conditions...

Indeterminate biliary strictures pose a diagnostic and therapeutic challenge. Although underlying malignancy is a primary concern, biliary strictures may result from benign processes. An accurate diagnosis is paramount to define the treatment strategy and minimize morbidity. The limitations of traditional endoscopic retrograde cholangiopancreatography-based tissue acquisition with cytology brushings are well-documented. Endoscopic retrograde cholangiopancreatography is generally unable to determine a stricture's etiology...

Cholangiocarcinoma is a rare malignancy and accounts for 2% of all malignancies. Incidence is on the increase in the Western world. Cholangiocarcinoma arises from the malignant growth of the epithelial lining of the bile ducts and can be found all along the biliary tree. It can be classified into subtypes based on location: intrahepatic (arising from the intrahepatic biliary tract in the hepatic parenchyma), perihilar (at the hilum of the liver involving the biliary confluence) and distal (extrahepatic, often in the head of the pancreas)...

Although the most common presentation of biliary disorder in North America is secondary to gallstone disease, an awareness of benign biliary cystic neoplasms is important because of the risk of malignant transformation. The incidence of premalignant cystic neoplasms of the bile duct is not well characterized and they often are detected incidentally for suspicion of other abdominal disorders. This article describes the 4 most common premalignant biliary cystic neoplasms: biliary mucinous cystic neoplasms, intraductal papillary mucinous neoplasms of the bile duct, intraductal tubular papillary neoplasms of the bile duct, and choledochal cysts...
