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: 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...

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...

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...

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...

Primary biliary mucosa-associated lymphoid tissue (MALT) lymphoma is extremely rare. We report a case of primary biliary MALT lymphoma with obstructive jaundice diagnosed by endoscopic biopsy, without surgical intervention. Obstructive jaundice was relieved by endoscopic drainage and endoscopic biopsy was done simultaneously during endoscopic retrograde cholangiopancreatography. Unnecessary surgical intervention can be avoided after pathological confirmation of lymphoma. The patient received radiotherapy, and is alive without any evidence of recurrence or biliary obstruction...

AIMS: The aim of this study was to achieve a better definition of intraductal papillary neoplasms of the bile duct (IPNBs). METHODS AND RESULTS: Biliary tumours that showed predominantly intraductal papillary growth were provisionally classified as IPNBs (n = 25) and papillary cholangiocarcinomas (n = 27). IPNB was defined as a neoplasm that is confined to the epithelium or is regularly arranged in a high-papillary architecture along thin fibrovascular stalks, whereas the term 'papillary cholangiocarcinoma' was used for tumours with more complex papillary structures (e...

BACKGROUND: Biliary strictures at the hilum of the liver arise from heterogeneous etiologies. The majority is malignant entities, but some may have benign etiologies. It is difficult to distinguish between malignant and benign biliary strictures preoperatively. It has been reported that 5~15 % of preoperative diagnoses of hilar cholangiocarcinoma turn out to be benign lesions or even other types of malignancies. Primary non-Hodgkin's lymphoma of the extrahepatic bile duct is very rare, with only a few cases reported as mucosa-associated lymphoid tissue (MALT) lymphoma arising from the hepatic duct bifurcation...

BACKGROUND AND OBJECTIVES: Angiopoietins (Angs) play a pivotal role in angiogenesis and inflammation, and are associated with prognosis in malignancies. Monocyte express Ang-receptor TIE2 and correlate with prognosis in cancer. We aimed to investigate the prognostic value of Angs and TIE2-expressing monocytes (TEMs) in cholangiocarcinoma. METHODS: We analyzed surgically resected tumor specimens of hilar cholangiocarcinoma (n = 47) for distribution of Angs (Ang 1/Ang 2) and TEMs, as defined by co-expression of CD14 and Ang receptor TIE2...

A 46-year-old woman underwent right hemihepatectomy, cholecystectomy, and sampling of the hilar lymph nodes for combined hepatocellular and cholangiocarcinoma. She received oral S-1 after hepatectomy. However, her serum level of carcinoembryonic antigen gradually increased, and solitary paraaortic lymph node recurrence was detected on positron emission tomography-computed tomography 12 months after hepatectomy. The patient underwent paraaortic lymph node dissection. Histologic examination revealed solitary paraaortic lymph node metastasis composed of hepatocellular carcinoma...

A 67-year-old man with elevated hepatobiliary enzymes was referred to our hospital for further examination. Computed tomography indicated hilar cholangiocarcinoma of Bismuth type Ⅳ and revealed invasion of the right hepatic artery and the left portal vein. We diagnosed locally advanced unresectable hilar cholangiocarcinoma, and performed 5 courses of chemotherapy with gemcitabine plus S-1. After chemotherapy, the tumor was significantly reduced in size and vascular invasions were alleviated, so we decided to perform surgical resection...

Prdx1 is an important member of peroxiredoxins (Prdxs) regulating various cellular signaling and differentiation. Prdx1 confers an aggressive survival phenotype of cancer cells and drug-resistance, yet its role in hilar cholangiocarcinoma is not fully investigated. In present study, we detected the expression profile of Prdx1 in 88 hilar cholangiocarcinoma by tissue arrays and immunohistochemistry. Prdx1 level was down-regulated by specific Prdx1-shRNA in vitro and the possible mechanism was investigated. Overexpression of Prdx1 was observed in 53 of 88 cases (60...

Hilar cholangiocarcinoma (CC) is non-resectable in the majority of patients often due to intrahepatic extension along bile duct branches/segments, and even after complete resection (R0) recurrence can be as high as 70%. Photodynamic therapy (PDT) is an established palliative local tumor ablative treatment for non-resectable hilar CC. We report the long-term outcome of curative resection (R0) performed after neoadjuvant PDT for downsizing of tumor margins in seven patients (median age 59 years) with initially non-resectable hilar CC...
