Introducción: las neoplasias de la vía biliar son infrecuentes y se asocian a alta mortalidad y mal pronóstico. Ocupan el quinto lugar entre los cánceres digestivos después de estómago, colon, recto y esófago. En Cuba existe un incremento en el diagnóstico de esta entidad. Objetivo: caracterizar clínica y endoscópicamente los tumores de la vía biliar de los pacientes. Métodos: se realizó una investigación descriptiva retrospectiva en pacientes que se realizaron colangiopancreatografía retrógrada endoscópica en el Centro de Investigaciones Médico Quirúrgicas entre enero del 2006 y diciembre del 2014. Se revisaron todos los informes de este proceder y se determinaron las variables sociodemográficas (edad y sexo), datos clínicos por lo que se realiza, diagnóstico endoscópico y terapéuticas endoscópicas realizadas. Resultados: se realizaron 830 colangiopancreatografías retrógradas endoscópicas y se diagnosticó tumor de la vía biliar en 73 (8,8 por ciento) pacientes y ampulomas en 40 (4,8 por ciento), predominó el grupo etario entre 60 y 69 años (31,0 por ciento), el 57,8 por ciento del total de pacientes era del sexo femenino, el principal dato clínico que motivó la indicación del proceder fue el síndrome ictérico que estuvo presente en el 76,7 por ciento del total de pacientes y la colocación de endoprótesis fue la terapéutica endoscópica más empleada (80,2 por ciento de los casos). Conclusión: predominaron los pacientes del sexo femenino y la sexta década de la vida, el tumor al nivel del hepático común fue más frecuente, la colangiopancreatografía retrógrada endoscópica desempeñó el papel principal en el diagnóstico y tratamiento paliativo de este grupo de pacientes(AU)

Introduction: neoplasms of the biliary tract are rare and are associated with high mortality and poor prognosis. It ranks fifth among gastrointestinal cancers after stomach, colon, rectum and esophagus. In Cuba there is an increase in the diagnosis of this entity. Objective: to characterize the clinical and endoscopic bile duct tumors of patients. Methods: a retrospective descriptive study in patients was conducted endoscopic retrograde cholangiopancreatography were performed in the CIMEQ Hospital between January 2006 and December 2014. To conduct the study were reviewed all reports of endoscopic retrograde cholangiopancreatography and sociodemographic variables (age and sex), clinical data so that the procedure is performed, endoscopic diagnosis and endoscopic treatment performed type are determined.

Caroli's disease is a rare autosomal-recessive disorder caused by malformation of the ductal plate during embryonic development. Although it is present at birth, Caroli's disease is typically not diagnosed until between the second and fourth decades of life, as it was in the present patient. Here we report a rare case of Caroli's disease limited to one liver segment, which was initially misdiagnosed as an intraductal papillary neoplasm of the bile duct. The asymptomatic patient was treated with liver segmentectomy.

Biliary papillomatosis is rare, and its pathogenic mechanisms are not yet clear. Because of its high risk for malignancy transformation, surgical resection is regarded as a standard treatment. Photodynamic therapy (PDT) has been used by the intravenous administration of hematoporphyrin derivative followed by laser exposure. A photochemical process causes disturbance of the microvascular structure and degradation of membrane. Cholangitis is a major complication after PDT. A healthy 56-year-old man was diagnosed with biliary papillomatosis involving the common hepatic duct, both proximal intrahepatic bile ducts (IHD), and the right posterior IHD. After biliary decompression by endoscopic nasobiliary drainage, PDT was performed to avoid extensive liver resection and recurrence using endoscopic retrograde cholangiographic guidance. After portal vein embolization, the patient underwent extended right hemihepatectomy. Following administration of chemoradiation therapy with tegafur-uracil and 45 Gy due to local recurrence at postoperative 13 months, there was no local recurrence or distant metastases. This is the first case report on PDT for biliary papillomatosis in Korea. Preoperative PDT is beneficial for reducing the lesion in diffuse or multifocal biliary papillomatosis and may lead to curative and volume reserving surgery. Thus, PDT could improve the quality of life and prolong life expectation for biliary papillomatosis patients.

Invasion of the bile duct by hepatocellular carcinoma (HCC), which is called intrahepatic bile duct HCC, is rare and has a poor prognosis. Early diagnosis and surgical resection is important for treatment. A 58-year-old man who underwent hepatic resection for HCC 4 years ago and received transarterial chemoembolization (TACE) 2 years after the operation for recurred HCC presented with jaundice. CT scan revealed a tumor in the common bile duct without intrahepatic lesion. Therefore, ERCP was done to perform biopsy and biliary drainage. Histological examination was compatible with hepatocellular carcinoma. However, the tumor could not be visualized at angiography and thus, only transarterial chemoinfusion was performed without embolization. The tumor had disappeared on follow-up CT scan, and the patient has been disease free for 23 months without evidence of recurrence. Herein, we report a case of intrahepatic bile duct HCC which disappeared after ERCP.

BACKGROUND/AIMS: Biliary drainage is performed in many patients with cholangiocarcinoma (CCA) to relieve obstructive jaundice. For those who have undergone biliary drainage, bile cytology can be easily performed since the access is already achieved. This study aims to determine the clinical usefulness of bile cytology for the diagnosis of CCA and to evaluate factors affecting its diagnostic yield. METHODS: A total of 766 consecutive patients with CCA underwent bile cytology via endoscopic nasobiliary drainage or percutaneous transhepatic biliary drainage from January 2000 to June 2012. Data were collected by retrospectively reviewing the medical records. We evaluated the diagnostic yield of bile cytology with/without other sampling methods including brush cytology and endobiliary forcep biopsy, and the optimal number of repeated bile sampling. Several factors affecting diagnostic yield were then analyzed. RESULTS: The sensitivity of bile cytology, endobiliary forceps biopsy, and a combination of both sampling methods were 24.7% (189/766), 74.4% (259/348), and 77.9% (271/348), respectively. The cumulative positive rate of bile sampling increased from 40.7% (77/189) at first sampling to 93.1% (176/189) at third sampling. On multivariate analysis, factors associated with positive bile cytology were perihilar tumor location, intraductal growing tumor type, tumor extent > or =20 mm, poorly differentiated grade tumor, and three or more samplings. CONCLUSIONS: Although bile cytology itself has a low sensitivity in diagnosing CCA, it has an additive role when combined with endobiliary forceps biopsy. Due to the relative ease and low cost, bile cytology can be considered a reasonable complementary diagnostic tool for diagnosing CCA.

Intraductal papillary mucinous neoplasm of the bile duct (IPMN-B) and intraductal papillary mucinous neoplasm of the pancreas (IPMN-P) have striking similarities and are recognized as counterparts. However, simultaneous occurrence of IPMN-B and IPMN-P is extremely rare. A 66 year-old female presented with recurrent epigastric pain and fever. During the past 9 years, she had three clinical episodes related to intrahepatic duct stones and IPMN-P in the pancreas head and was managed by medical treatment. Laboratory test results at admission revealed leukocytosis (12,600/mm3) and elevated CA 19-9 level (1,200 U/mL). Imaging study demonstrated liver abscess in the Couinaud's segment 4, IPMN-B in the left lobe, and IPMN-P in the whole pancreas with suspicious malignant change. Liver abscess was drained preoperatively, followed by left lobectomy with bile duct resection and total pancreatectomy with splenectomy. On histologic examination, non-invasive intraductal papillary mucinous carcinoma arising from various degree of dysplastic mucosa of the liver and pancreas could be observed. However, there was no continuity between the hepatic and pancreatic lesions. This finding in our case supports the theory that double primary lesions are more likely explained by a diffuse IPMN leading to synchronous tumors arising from both biliary and pancreatic ducts rather than by a metastatic process. Herein we present a case of simultaneous IPMN of the bile duct and pancreas which was successfully treated by surgical management.

Neuroendocrine tumors of the extrahepatic biliary tree are extremely rare malignancies accounting for 0.2-2.0% of all gastrointestinal carcinoid tumors. Neuroendocrine tumors obstructing the biliary tree are extremely difficult to diagnose preoperatively and nearly impossible to differentiate from cholangiocarcinoma. Statistically, the most common anatomic location in the biliary tree is the common bile duct, followed by the perihilar region. Herein, we present a case of a small cell neuroendocrine carcinoma of the hilum in a 79-year-old man following laparotomy. To our knowledge, this is the first case of small cell type neuroendocrine carcinoma of hilar bile duct reported in Korea.

BACKGROUND/AIMS: Few studies have assessed the prognostic value of the primary tumor maximum standardized uptake value (SUVmax) measured by 2-[18F]-fluoro-2-deoxy-D-glucose PET-CT for patients with bile duct and gallbladder cancer. METHODS: A retrospective analysis of 61 patients with confirmed bile duct and gallbladder cancer who underwent FDG PET-CT in Kangbuk Samsung Medical Center (Seoul, Korea) from April 2008 to April 2011. Prognostic significance of SUVmax and other clinicopathological variables was assessed. RESULTS: Twenty-three patients were diagnosed as common bile duct cancer, 17 as hilar bile duct cancer, 12 as intrahepatic bile duct cancer, and nine as gallbladder cancer. In univariate analysis, diagnosis of intrahepatic cholangiocarcinoma and gallbladder cancer, mass forming type, poorly differentiated cell type, nonsurgical treatment, advanced American Joint Committee on Cancer (AJCC) staging and primary tumor SUVmax were significant predictors of poor overall survival. In multivariate analysis adjusted for age and sex, primary tumor SUVmax (hazard ratio [HR], 4.526; 95% CI, 1.813-11.299), advanced AJCC staging (HR, 4.843; 95% CI, 1.760-13.328), and nonsurgical treatment (HR, 6.029; 95% CI, 1.989-18.271) were independently associated with poor overall survival. CONCLUSIONS: Primary tumor SUVmax measured by FDG PET-CT is an independent and significant prognostic factor for overall survival in bile duct and gallbladder cancer.

Primary mucosa-associated lymphoid tissue (MALT) lymphoma arising in the common bile duct (CBD) is extremely rare. In our case of MALT lymphoma, CT and MRI showed long, segmental, irregular wall thickening of the CBD and minimal dilatation of the upstream bile duct. A preoperative diagnosis of cholangiocarcinoma was made, but histologic evaluation confirmed MALT lymphoma of the CBD. We herein present a rare case of MALT lymphoma of the CBD with CT and MRI findings.

A 64-year-old male patient with liver cirrhosis underwent a CT study for hepatocellular carcinoma surveillance, which demonstrated a 1.4-cm hypervascular subcapsular tumor in the liver. On gadoxetic acid-enhanced MRI, the tumor showed brisk arterial enhancement and persistent hyperenhancement in the portal phase, but hypointensity in the hepatobiliary phase. On diffusion-weighted MRI, the tumor showed an apparent diffusion coefficient twofold greater than that of the background liver parenchyma, which suggested that the lesion was benign. The histologic diagnosis was intrahepatic bile duct adenoma with alcoholic liver cirrhosis.

Anomalous union of the pancreaticobiliary duct (AUPBD) is a congenital anomaly that is defined as a junction of the bile duct and pancreatic duct outside the duodenal wall. This anomaly results in a loss of normal sphincteric mechanisms at the pancreaticobiliary junction. As a result, regurgitation of pancreatic juice into the biliary system develops and causes choledochal cysts, choledocholithiasis, cholangitis, pancreatitis and malignancy of the biliary tract. Gallbladder cancer or common bile duct cancer associated with AUPBD and choledochal cysts have been frequently reported. But, intrahepatic cholangiocarcinoma associated with this condition has been only rarely reported. Here, we report a case of intrahepatic cholangiocarcinoma associated with AUPBD and choledochal cyst.

Colloid carcinoma of the liver is very rare, and its clinicopathologic features have not been well characterized yet. We describe herein a case of colloid carcinoma of the liver. Imaging revealed a lobulated mass, measuring 12 cm in diameter at the right lobe of the liver with direct invasion of adjacent peripheral intrahepatic bile ducts. Right hemihepatectomy of the liver was performed according to the possibility of the tumor's malignant behavior. Histopathological examination of the specimen revealed large extracelluar stromal mucin pools containing floating cuboidal to columnar neoplastic cells without ovarian-like stroma. This case seemed to be colloid carcinoma arising in association with intraductal papillary neoplasm of the liver.

Cholangiocarcinoma is a rare disease in the western World, but it comprises a diagnostic and therapeutic challenge. Its outcome strongly depends on early diagnosis and complete surgical resection. As of today there are no surgical procedures that have proved increase in the survival rate for patients with these types of tumors. Recently, liver transplant appears as a promising alternative reporting a survival rate over 80 percent in 5 years. However, it has been impossible to replicate these results in the majority of the Centers specialized in the management of this disease. The present article shows epidemiological data of the disease, diagnostic methods and options of treatment according to the staging.

El colangiocarcinoma es una patología infrecuente en el mundo occidental, pero representa un desafío diagnóstico y terapéutico. Su pronóstico es muy dependiente de la precocidad del diagnóstico y la resección quirúrgica completa. Hasta ahora no existen terapias no quirúrgicas que hayan demostrado aumentar la sobrevida para este tipo de tumores. Últimamente, el trasplante de hígado aparece como una alternativa promisoria con reportes de sobrevida por sobre el 80 por ciento a 5 años, sin embargo, estos resultados no han podido ser replicados por la mayoría de los centros con alta experiencia en el manejo de esta enfermedad. En el presente artículo se detallan los antecedentes epidemiológicos de la enfermedad, los métodos diagnósticos y opciones de tratamiento según el estadío.
