BACKGROUND: Bilateral stent-in-stent (SIS) self-expandable metal stent placement is technically challenging for palliation of unresectable malignant hilar obstruction. In the SIS technique, the uniform large cell type biliary stent facilitates contralateral stent deployment through the mesh of the first metallic stent. This study aimed to assess the technical success and clinical effectiveness of this technique with a uniform large cell type biliary stent. METHODS: Thirty-one patients who underwent bilateral SIS placement using a large cell type stent were reviewed retrospectively...

BACKGROUND AND STUDY AIMS: The diagnosis of cholangiocarcinoma (CCA) is difficult. The present study aimed to assess the clinical features, diagnosis, and survival in CCA. PATIENTS AND METHODS: This is a prospective study on 46 patients with CCA who underwent endoscopic retrograde cholangiopancreatography (ERCP) or surgical resection and 20 controls with a clinical and ERCP suspicion for CCA in whom surgical biopsy and/or 4-year follow-up showed a benign biliary stricture...

In the most common surgical procedure for perihilar cholangiocarcinoma, the margin status of the proximal bile duct is determined at the final step. Our procedure, the transhepatic hilar approach, confirms a cancer-negative margin status of the proximal bile duct first. We first performed a partial hepatic parenchymal transection to expose the hilar plate, and then transected the proximal bile duct to confirm margin status. Then, divisions of the hepatic artery and portal vein of the future resected liver are performed, followed by the residual hepatic parenchymal transection...

BACKGROUND: Curative hepatectomy with bile duct resection is the treatment for perihilar cholangiocarcinoma. A locally advanced tumor necessitates hepatectomy with simultaneous vascular resection, and reconstruction remains an obstacle for surgeons. Studies have focused on the variations of hepatic arteries. Nevertheless, the anatomical alignment of the portal veins, bile ducts, and hepatic arteries are equally critical in surgical planning of curative resection for advanced tumors. We have reported promising outcomes of hepatectomy with simultaneous resection and reconstruction of the hepatic artery...

IgG4-related disease represents a heterogeneous group of disease characterized by infiltration of various tissues by IgG4 plasmocytes. In case of liver infiltration, this condition classically mimics primary sclerosing cholangitis or multifocal cholangiocarcinoma due to inflammation that preferentially affects the intra- and extrahepatic bile duct. Diagnostic criteria have recently been reviewed in order to better define the disease and help physicians make the diagnosis. Herein, we present the case of a patient who died after liver surgery for suspected cholangiocarcinoma that finally turned out to be IgG4-associated liver disease, a condition being out of current consensual criteria...

Biliary tract cancers (BTC) are aggressive gastrointestinal malignancies that are associated with a poor prognosis. This rare group of tumors includes cancers of the gallbladder, intrahepatic, and extrahepatic biliary tree. Chronic inflammatory processes such as cholelithiasis and chronic bacterial infection of the biliary system remain the most common underlying risk factor although most cases occur sporadically. The majority of patients present with advanced disease accompanied by nonspecific symptoms, making BTCs a therapeutic challenge for clinicians...

Biliary tract cancers (BTC) are malignancies that arise from the epithelium of the biliary system and comprise the second most common type of hepatobiliary cancer worldwide. BTC are sub-classified as intrahepatic cholangiocarcinoma (iCCA), perhilar/hilar cholangiocarcinoma (pCCA), distal cholangiocarcinoma (dCCA), and gallbladder carcinoma. Due to the differences in their etiologic risk factors, pathogenesis, and molecular and genetic characteristics, each of these subtypes is considered a separate biological entity...

BACKGROUND: Because of its high rate of early recurrence and its poor prognosis, long-term survival after cholangiocarcinoma is rare; therefore, only limited information on patients surviving more than 5 years after surgical therapy is available. CASE PRESENTATION: We report the case of a 57-year-old white man who developed a distal bile duct carcinoma 9 years after curative surgical therapy of intrahepatic cholangiocarcinoma. He had undergone a right lobe hemihepatectomy 11 years ago...

PURPOSE: The purpose of this study is to investigate the value of multidetector computed tomography (MDCT) assessment of resectability in hilar cholangiocarcinoma, and to identify the factors associated with unresectability and accurate evaluation of resectability. METHODS: From January 2007 to June 2015, a total of 77 consecutive patients were included. All patients had preoperative MDCT (with MPR and MinIP) and surgical treatment, and were pathologically proven with hilar cholangiocarcinoma...

Mantel et al. showed that the use of intraoperative frozen section analysis of the proximal bile ducts has a limited contribution in obtaining secondary R0 resections and final resection status had no impact on recurrence rate in hilar cholangiocarcinoma. However, the accuracy, sensitivity, and specificity of intraoperative frozen section analysis were determined by the specific pathologic features of the tumor and the different experienced pathologists in different pathology laboratories. It has been demonstrated that tumor-free resection margin (R0) is the most prognostic factor for survival, as well as the only factor that can be modified by the surgeons...

BACKGROUND: Accurate preoperative radiological staging of biliary cancers remains difficult. Despite the improvement in imaging techniques, a number of patients with biliary cancers who undergo laparotomy are ultimately found to have unresectable diseases. The goals of staging laparoscopy (SL) are to rule out metastatic and locally advanced unresectable diseases and better define locally advanced unresectable diseases. This study evaluates the efficiency of SL in ruling out unresectable disease in a subset of biliary cancers...

Dickkopf-1 (DKK1) is involved in tumorigenesis and the invasion of several tumors. However, its biological function in human hilar cholangiocarcinoma (HCCA) has not yet been documented. This study was designed to investigate the clinical significance and biological function of DKK1 in HCCA. The expression of DKK1 was investigated in thirty-seven human HCCA biopsy samples by immunohistochemistry. To further explore the biological effects of DKK1 in HCCA, transient and stable knockdown of DKK1 in two human HCCA cells (QBC939 and FRH0201) were established using small interfering or short hairpin RNA expression vector...

Hepato-pancreato-biliary (HPB) tumors are common in China. However, these tumors are often diagnosed at intermediate/ advanced stages because of the lack of a systemic surveillance program in China. This situation creates many technical challenges for surgeons and increases the incidence of postoperative complications. Therefore, Dr. Xiao-Ping Chen has made many important technical improvements, such as Chen's hepatic portal occlusion method, the anterior approach for liver resection of large HCC tumors, the modified technique of Belghiti's liver-hanging maneuver, inserting biliary-enteric anastomosis technique, and invaginated pancreaticojujunostomy with transpancreatic U-sutures...

Importance: The prognostic value of lymph node (LN) assessment after liver resection for hilar cholangiocarcinoma (HC) is still controversial, and the number of LNs required to be removed to obtain adequate staging is not well defined. Objectives: To evaluate the LN status in patients after liver resection for HC and to clarify which prognostic factor (the number of positive LNs or the LN ratio [LNR]) was most accurate for staging and what minimum number of retrieved LNs was required for adequate staging...
