INTRODUCTION: Serum liver biomarkers (gamma-glutamyl transferase, GGT; alanine aminotransferase, ALT; aspartate aminotransferase, AST; alkaline phosphatase, ALP; total bilirubin) are used as indicators of liver disease, but there is currently little data on their prospective association with risk of hepatobiliary cancers. METHODS: A nested-case control study was conducted within the prospective EPIC cohort (>520,000 participants, 10 European countries). After a mean 7...

BACKGROUND: Perihilar cholangiocarcinoma has one of the poorest prognoses of all cancers. However, mortality and morbidity rates after surgical resection are 0-15% and 14-66%, respectively. Additionally, the 5-year overall survival rates are reported at 22-40%. These findings indicate that only selected patients achieve satisfactory beneficial effects from operative treatment. This retrospective study sought to investigate preoperatively available prognostic factors and establish a new preoperative staging system to predict survival after major hepatectomy of perihilar cholangiocarcinoma...

UNLABELLED: Primary sclerosing cholangitis (PSC) is a chronic inflammatory liver disease of unknown etiology, primarily targeting cholangiocytes at any portion of the biliary tree. No effective medical treatments are currently available. A unique feature of PSC is its close association (about 80%) with inflammatory bowel disease (IBD), mainly ulcerative colitis (UC). As in many chronic inflammatory conditions, cancer development can complicate PSC, accounting for >40% of deaths. Cholangiocarcinoma (CCA), gallbladder carcinoma (GBC) and colorectal carcinoma (CRC) have been variably associated to PSC, with a prevalence up to 13-14%...

BACKGROUND: In the current American Joint Committee on Cancer/International Union Against Cancer staging system (seventh edition) for intrahepatic cholangiocarcinoma (ICC), tumor size was excluded, and periductal invasion was added as a new tumor classification-defining factor. The objective of the current report was to propose a new staging system for ICC that would be better for stratifying the survival of patients based on data from the nationwide Liver Cancer Study Group of Japan database...

BACKGROUND: Endoscopic biliary drainage (EBD) and percutaneous transhepatic biliary drainage (PTBD) are both used to resolve jaundice before surgery for perihilar cholangiocarcinoma (PHC). PTBD has been associated with seeding metastases. The aim of this study was to compare overall survival (OS) and the incidence of initial seeding metastases that potentially influence survival in patients with preoperative PTBD versus EBD. METHODS: Between 1991 and 2012, a total of 278 patients underwent preoperative biliary drainage and resection of PHC at 2 institutions in the Netherlands and the United States...

BACKGROUND: With advances in laparoscopic instrumentation and acquisition of advanced laparoscopic skills, laparoscopic common bile duct exploration (LCBDE) is technically feasible and increasingly practiced by surgeons worldwide. Traditional practice of suturing the dochotomy with T-tube drainage may be associated with T-tube-related complications. Primary duct closure (PDC) without a T-tube has been proposed as an alternative to T-tube placement (TTD) after LCBDE. The aim of this meta-analysis was to evaluate the safety and effectiveness of PDC when compared to TTD after LCBDE for choledocholithiasis...

BACKGROUND: The complexity of hepatic hilar anatomy is an obstacle to precise diagnosis of tumor spread and appropriate operative planning for biliary malignancies. Three-dimensional (3D) cholangiography and angiography may overcome this obstacle and facilitate curative resection. The objective of this study was to evaluate the impact of 3D CT cholangiography on operative planning and outcomes of biliary malignancies. METHODS: From 2009 to 2014, 3DCT cholangiography was performed on 49 patients with biliary malignancies requiring major hepatic resection and extrahepatic bile duct resection...

BACKGROUND: Cholangiocarcinoma is the most common primary tumor of the biliary tract although it accounts for only 2 % of all human malignancies. We herein review hilar cholangiocarcinoma including its risk factors, the main classification systems for tumors, current surgical management of the disease, and the role chemotherapy and liver transplantation may play in selected patients. METHODS: We performed a comprehensive literature search using PubMed, Medline, and the Cochrane library for the period 1980-2015 using the following MeSH terms: "hilar cholangiocarcinoma", "biliary cancer", and "cholangiocarcinoma"...

BACKGROUND: The influence of margin status on long-term outcome of patients undergoing liver resection for intrahepatic cholangiocarcinoma (ICC) remains controversial. We sought to study the impact of surgical tumor margin status on recurrence-free survival (RFS) and overall survival (OS) of patients undergoing resection for ICC. METHODS: From a multi-institutional database, 583 patients who underwent hepatic resection for ICC were identified. Demographics data, operative details, pathologic margin status, and long-term outcomes were collected and analyzed...

BACKGROUND: In 2009, a study from our institution used retrospective data and multivariate analysis to identify 5 quantitative variables and their cutoffs that have a positive predictive value (PPV) for common bile duct (CBD) stones in gallstone pancreatitis. They also proposed a management protocol based on the scoring system. This prospective study sought to validate that scoring system. METHODS: From October 2009 to August 2013, patients with gallstone pancreatitis were enrolled in the study...

REVIEW
Bas Groot Koerkamp, Yuman Fong
The biliary malignancies that are reviewed here are gallbladder cancer (GBC), intrahepatic cholangiocarcinoma (IHC), and perihilar cholangiocarcinoma (PHC). The focus is on outcomes after potentially curative resection of biliary malignancies. Key outcomes are postoperative mortality, median and 5-year overall survival (OS), recurrence-free survival, and recurrence patterns. Poor prognostic factors for recurrence and survival as well as prognostic models are also discussed. The incidence of biliary malignancies in the United States is about 5 in 100,000...

AIM: To identify the influence of the surgery type and prognostic factors in middle and distal bile duct cancers. METHODS: Between August 1990 and June 2011, data regarding the clinicopathological factors of 194 patients with surgical and pathological confirmation were collected. A total of 133 patients underwent resections (R0, R1, R2; n = 102, 24, 7), whereas 61 patients underwent nonresectional surgery. Either pancreaticoduodenectomy (PD) or bile duct resection (BDR) was selected according to the sites of tumors and co-morbidities of the patients after confirming resection margin by the frozen histology in all cases...

IgG4 related cholangiopathy, a distinctive type of cholangitis of unknown origin, is characterized by increased serum levels of IgG4, massive infiltration of IgG4-positive plasma cells with storiform fibrosis and/or obliterative phlebitis in the thickened bile duct wall, and good response to steroids. Patients with IgG4-cholangiopathy are frequently associated with autoimmune pancreatitis; IgG4-cholangiopathy is recognized as a biliary manifestation of IgG4-related disease. This condition can be diagnosed by a combination of imaging, serology, histopathology, and steroid responsiveness; however, cholangiographic features are often difficult to differentiate from primary sclerosing cholangitis, pancreatic cancer, or cholangiocarcinoma...

Cholangiocarcinoma represents a diverse group of epithelial cancers united by late diagnosis and poor outcomes. Specific diagnostic and therapeutic approaches are undertaken for cholangiocarcinomas of different anatomical locations (intrahepatic, perihilar, and distal). Mixed hepatocellular cholangiocarcinomas have emerged as a distinct subtype of primary liver cancer. Clinicians need to be aware of intrahepatic cholangiocarcinomas arising in cirrhosis and properly assess liver masses in this setting for cholangiocarcinoma...

Sumera Rizvi, Gregory J Gores
Cholangiocarcinomas (CCAs) are hepatobiliary cancers with features of cholangiocyte differentiation; they can be classified anatomically as intrahepatic CCA (iCCA), perihilar CCA (pCCA), or distal CCA. These subtypes differ not only in their anatomic location, but in epidemiology, origin, etiology, pathogenesis, and treatment. The incidence and mortality of iCCA has been increasing over the past 3 decades, and only a low percentage of patients survive until 5 years after diagnosis. Geographic variations in the incidence of CCA are related to variations in risk factors...

Objectives. To evaluate, in hilar cholangiocarcinoma (HCCA), the prognostic impact of specific preoperative radiologic parameters on resectability, metastases, and yield of laparoscopy, and to evaluate the currently used staging systems. Methods. Consecutive patients with HCCA presenting in our center from January 2003 through August 2010 were evaluated. Suspicion on lymph node metastasis, portal vein and hepatic artery involvement, lobar atrophy, and proximal extent of ductal invasion was scored. The prognostic value of these parameters for predicting resectability, yield of diagnostic laparoscopy, likelihood of metastatic disease, R0 resection, and survival was assessed...

For decades, one well-known risk factor for the development of gallbladder stones has been hypothyroidism. Recent studies have interestingly reported that the risk in particular for common bile duct (CBD) stones increases in clinical and subclinical hypothyroidism. There are multiple factors that may contribute to the formation and/or accumulation of CBD stones in hypothyroid patients, including decreased liver cholesterol metabolism, diminished bile secretion, and reduced sphincter of Oddi relaxation. This paper focuses on the mechanisms possibly underlying the association between hypothyroidism and CBD stones...

Chronic complications of symptomatic gallstone disease, such as Mirizzi syndrome, are rare in Western developed countries with an incidence of less than 1% a year. The importance and implications of this condition are related to their associated and potentially serious surgical complications such as bile duct injury, and to its modern management when encountered during laparoscopic cholecystectomy. The pathophysiological process leading to the subtypes of Mirizzi syndrome has been explained by means of a pressure ulcer caused by an impacted gallstone at the gallbladder infundibulum, leading to an inflammatory response causing first external obstruction of the bile duct, and eventually eroding into the bile duct and evolving to a cholecystocholedochal or cholecystohepatic fistula...

OBJECTIVES To examine the outcomes of a hepatectomy for intrahepatic cholangiocarcinoma (IHC) and to clarify the prognostic impact of a lymphadenectomy and the surgical margin. Large series of patients who were surgically treated for IHC are scarce. Thus, prognostic factors and long-term survival after resection of IHC remain uncertain. DESIGN Prospective study of patients who were surgically treated for IHC. Clinicopathologic, operative, and long-term survival data were analyzed. SETTING Prospectively collected data of all consecutive patients with pathologically confirmed IHC who had undergone liver resection with a curative intent at 1 of 16 tertiary referral centers were entered into a multi-institutional registry...

Hilar cholangiocarcinoma, also known as Klatskin tumour, is the commonest type of cholangiocarcinoma. It poses unique problems in the diagnosis and management because of its anatomical location. Curative surgery in the form of major hepatic resection entails significant morbidity. About 5-15% of specimens resected for presumed Klatskin tumour prove not to be cholangiocarcinomas. There are a number of inflammatory, infective, vascular, and other pathologies, which have overlapping clinical and radiological features with a Klatskin tumour, leading to misinterpretation...
