Cholangiocarcinomas (CCCs) are malignancies of the biliary duct system Perihilar tumors, also called Klatskin tumors (after Klatskin’s description of them in The etiology of most bile duct cancers remains undetermined.

The type of surgery and the extent of the resection depend on the location of the tumor and the degree of extension. The European multicentre study published in by Farges et al.
The groups were homogeneous in terms of age, tumour stage and portal resection.
Only comments seeking to improve the quality and accuracy of information on the Orphanet website are accepted. From Wikipedia, the free encyclopedia. This study shows that although it is true that biliary drainage increases the incidence of postoperative sepsis, biliary drainage should be performed in those patients who are going to be subjected to right hepatectomy to reduce the morbimortality associated with postoperative liver failure, and other studies support this theory.
Sin embargo, les fue mejor a los pacientes con un hallazgo incidental de CC, ganglios negativos y que no hubiera enfermedad residual. Surgery using extended liver resections with an en bloc klatskij of the liver with vascular reconstruction is the technique with the highest survival. In most of these series, liver resection is routinely performed. Prediction of drainage effectiveness during endoscopic stenting dw malignant hilar strictures: A number of pathologic conditions, however, resulting in either acute or chronic biliary tract epithelial injury may predispose to malignant change.
Endosonography EUS guided fine needle aspiration FNA of hilar lymph nodes is the most useful tool in the diagnosis and staging of Klatskin tumors. Focal nodular hyperplasia Nodular regenerative hyperplasia.
It would appear that although hepatectomy increases the probability of negative surgical margin, and therefore a greater chance of cure; an increase in postoperative mortality would be expected. A spectrum of intrahepatic, perihilar, and distal tumors.
Papillary phenotype confers improved survival after resection of hilar cholangiocarcinoma. Medullary carcinoma of the breast Medullary thyroid cancer.
Therefore, percutaneous transhepatic catheters provide the best access for palliation of inoperable hilar cholangiocarcinoma. Only comments written in English can be processed. More recently, the use of magnetic resonance cholangiopancreatography MRCP has been able to clearly identify the site and nature of biliary obstruction in a noninvasive manner.
Adenocarcinoma Familial adenomatous polyposis Hereditary nonpolyposis colorectal cancer. Solo el trabajo de De Palma 38 es prospectivo y aleatorizado y al comparar el stent unilateral versus bilateral no se demuestra que el drenaje klatskn curse con una menor morbimortalidad, por lo que no recomiendan el drenaje bilateral de rutina.
Helical CT assessment in hilar cholangiocarcinoma: The group without preoperative drainage non-PBD was composed of patients, and the group with biliary drainage PBD contained patients. Compromiso de la confluencia y el conducto biliar derecho a o izquierdo b y Tipo IV: Patterns and prognostic significance of klatsoin node dissection for surgical treatment of perihilar and intrahepatic cholangiocarcinoma.
Radiother Oncol, 99pp. Dig Dis Sci ; Summary Epidemiology The prevalence is unknown. The impact of portal vein resection on outcomes for hilar cholangiocarcinoma: Major liver resection for carcinoma in jaundiced patients without preoperative biliary drainage.
Another preoperative classification used in the USA is the one published by Jarnagin et al. At completion of preoperative staging, approximately two-thirds of patients with Klatskin tumors will be considered operable. Other diagnostic tests for this type of tumour would be: Non-specific complaints, such as weight loss and abdominal pain, may also occur.
Surgical resection involves a liver resection with caudate lobectomy in order to achieve a higher chance of negative resection margins. Left hepatectomy for Klatskin’s tumour, with resection of the portal vein: Relief of biliary blockage and resection of disease are the main goals of treatment.
In the study published by Ebata et al.
SONOWORLD : Klatskin tumor
Internist Berlin in German. In selected patients with locally advanced unresectable cancer at the porta, there are two options: Journal of the National Cancer Institute ; Complete resection with histologically negative resection margins R0nodal involvement and metastases are the most important prognostic factors.
Brush cytology and percutaneous biopsies have a low sensitivity for diagnosis. Endoscopic nasobiliary drainage is the most suitable preoperative biliary drainage method in the management of patients with hilar cholangiocarcinoma. Of klatsoin 87 patients with perihilar tumors undergoing palliative procedures, 4 4.
Its concentration in these patients varies widely and does not correlate with tumour size, although it does correlate with metastatic involvement.
