Background: Bile duct atresia (BVA) is a condition that causes obstruction to biliary flow, not corrected surgically, causes cirrhosis and death before 2 years of age. In Mexico from 2013 the visual colorimetric card (VVC) was incorporated for the timely detection of BVA to the National Health Card (NHC). The aim of this study was to evaluate the impact of VCT for the detection of BVA before and after the use of NHC incorporation. Methods: Ambispective, analytical observational study...

Percutaneous drainage of the bile ducts is an established procedure for malignant obstructions, in which a histological diagnosis is often not obtained. We describe the biopsy technique of obstructive lesions through biliary drainage access, using a 7F endoscopic biopsy forceps, widely available; some are even reusable. This technique applies to lesions of the hepatic ducts, of the common hepatic duct and of all extension of the common bile duct. RESUMO A drenagem percutânea das vias biliares é um procedimento estabelecido para obstruções malignas, nos quais, muitas vezes, não se consegue um diagnóstico histológico...

 We present the case of a 56-yr-old woman with vague abdominal pain of approximately 5 months duration. An ultrasound study showed moderate dilation of the common bile duct. Magnetic resonance cholangiopancreatography confirmed a cystic dilatation of the right hepatic duct with intra and extra hepatic component. The patient underwent right hepatectomy and complete excision of the cyst. Microscopically, the cyst wall was formed by fibrous tissue with mild acute and chronic inflammatory infiltrate, the inner surface showed a single layer of columnar epithelium and extensive squamous metaplasia without atypia, wich expressed p63 and high molecular weight cytoqueratin (34BE12)...

Autoimmune pancreatitis (AIP) was recognized as a clinical entity, at least in the West little more than 10 years ago. Since then, studies globally, and international collaboration, have led to important advances in our understanding of its clinical features, disease course, and management, although the aetiopathogenesis of this curious disease remains to be fully elucidated. Types 1 and 2 AIP have been described, of which type 1 is the commonest form, and best defined. International consensus now recognizes it as one of the many clinical manifestations of IgG4-related disease, and is now termed IgG4-related pancreatitis (IgG4-RP)...

Gastroenteropancreatic neuroendocrine tumors are known for their aggressiveness. Diagnosis of various bile duct pathologies, like biliar intraepithelial neoplasm, mixed adenoneuroendocrine carcinomas or small cell carcinomas, is challenging. This case report focuses on a rare case of a focal primary minute small cell carcinoma in the vicinity of the extrahepatic bile duct, presenting itself next to an extensive biliar intraepithelial neoplasm. This finding led to adjuvant chemotherapy, followed by major surgery...

Surgery of the biliary tract is complex, and its volume has increased with iatrogenic injuries and living donor transplantation. The aim of this study was to analyze if the common duct can be temporarily replaced. We used nine 18-20 kg pigs. They were operated on, and their bile duct was replaced by a 100% silicone tube. All pigs underwent laboratory tests, magnetic resonance imaging, intraoperative ultrasound, cholangiography and biliar manometry with pathological biopsy examination within 60 days from the initial surgery...

The program of actions for the assessment of severity of biliar sepsis and the choice of algorithms for relevant medical-diagnostic measures is presented. The account is taken of the traumatic factor of operation, the method of narcosis (endotracheal, local anaesthesia) and severity of the initial condition in individual patients. It is suggested to use this program in the form of computer software for the diagnosis of severity of the disease in septic patients, creation of the database and electron archives of the results of the treatment for the purpose of continuous monitoring the patients' conditions...

INTRODUCTION: Biliary tract injuries (BTI) represent the most serious and potentially life-threatening complication of cholecystectomy. During open cholecystectomies (OC), the prevalence of bile duct injuries has been estimated at only 0.1-0.2%. We report 3 cases of BTI during laparoscopic cholecystectomy (LC). CASE 1: Ascalesi Hospital, Naples 2003-2007, 875 LC (BTI 0,11%). During the dissection of triangle of Calot a partial resection of biliary common duct was made. Immediately the lesion was evident and sheltered in laparoscopy, suturing with a spin reabsorbable, without biliar drainage...

UNLABELLED: Pancreatic cancer is a great surgical problem. Clinical observations confirm 10-15% level of R0 resection ability. Dissatisfying treatment effects results from: lach of simple screening tests, low specificity of methods used to diagnose less than 2 cm lesions, low availability of advanced diagnostic methods (endoscopic ultrasonography), anatomy of pancreatoduodenic area, ability of infiltration adhering structures and causing metastatic tumors. AIM: Retrospective evaluation of treatment methods administered to patients with pancreatic cancer according to different clinical stages...

More than 80% of primary liver cancers are hepatocellular carcinoma. The second most frequent primary tumors of the liver are cholangiocarcinomas, accounting for about 15% of primary liver cancers. Less frequent tumor types is the combined hepatocellular-cholangiocarcinoma (CHC), a rare primary liver tumor showing both hepatocellular and bile duct differentiation, and mostly represent less than 5% of primary liver cancer The histogenesis of CHC has been unclear Differentiation potential of hepatocyte and biliar epithelium is closely related to the common embryonic origin and various states of cellular differentiation...

Cholestasis includes, as a syndrome, all clinical and biological manifestations caused by the deficient or simply absent biliar secretion or caused by the obstruction of the biliary ducts. The hepatic cholestasis from the chronic hepatitis C (HC VHC) is a result of the altered interlobular biliary canalicules, caused by the modified cellular transport mechanisms and it is associated with a medium to severe degree of fibrosis. The aim of this study was to evaluate the efficiency of antiviral therapy in HC VHC patients...

According to the OMS classification of the epithelial benign neoplasm of the liver, the adenomas represent the most important group. In literature an increase of their incidence in the last years is reported especially in the female sex, in relationship to the diffusion of the use of hormonal contraceptives. The biliar cistoadenoma (BCA) represents a not frequent neoplasm of the liver that has origin on the inside of the liver, and less frequently from the extrahepatic biliar system. The surgical interest is underlined by the potentiality of the malignant evolution of the lesion and by its high tendency to the relapse...

The primitive tumors of the liver are relatively rare in the Western countries (around the 0.7% of all the neoplasms) while they present more elevated incidence in Africa and in the South Asian East. While the hepatocellular carcinoma rises up in the 50-70% of the cases in livers cirrosis, this correlation is not valid for the form of carcinoma to departure from the learned intra and extra biliar. The etiology of the intrahepatic colangiocarcinoma (CC) stays unknown. They have stayed observe, on the other hand, of the conditions sometimes correlated to the development of the CC (Carolí morbs, ulcerative colitis, asbestosis)...
