RESUMO
Portal hypertensive biliopathy (PHB) is characterized by anatomical and functional abnormalities of the intrahepatic, extrahepatic and pancreatic ducts, in patients with portal hypertension associated to extrahepatic portal vein obstruction and less frequently to cirrhosis. These morphological changes, consisting in dilatation and stenosis of the biliary tree, are due to extensive venous collaterals occurring in an attempt to decompress the portal venous blockage. It is usually asymptomatic until it progresses to more advanced stages with cholestasis, jaundice, biliary sludge, gallstones, cholangitis and finally biliary cirrhosis. Imaging modalities of the biliary tree such as Doppler ultrasound, computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are essential to establish the diagnosis and the need of therapeutical interventions. Once the diagnosis is established, treatment with ursodesoxycholic acid seems to be beneficial. Decompression of the biliary tree to dilate, remove stones or implant biliary prosthesis by endoscopic or surgical procedures (hepato-yeyunostomy) usually resolves the cholestatic picture and prevents septic complications. The ideal treatment is the decompression of the portal system, with transjugular intrahepatic porto-systemic shunt or a surgical porto-systemic shunt. Unfortunately, few patients will be candidates for these procedures due to the extension of the thrombotic process. The purpose of this paper is to report the first 3 cases of PHB seen in a Colombian center and to review the literature.
RESUMO
La enfermedad hepática por infiltración grasa no alcohólica (NAFLD) es la más frecuente en las sociedades desarrolladas, comprometiendo 2-8% de la población general, y en las nuestras está en camino de serlo. Es generalmente asintomática o con síntomas y signos inespecíficos como fatiga, hepatomegalia y dolor, o sensación de peso en el hígado. El diagnóstico se sospecha en presencia de pruebas hepáticas o imágenes diagnósticas anormales. La biopsia hepática es el estándar diagnóstico. Existe una clara relación con la obesidad, la diabetes tipo 2, el síndrome metabólico y la resistencia a la insulina. Aproximadamente, 20-25% de los pacientes progresan a cirrosis y sus complicaciones, incluyendo el carcinoma hepatocelular y la necesidad de un trasplante hepático. La corrección de la resistencia a la insulina con modificaciones dietéticas y el aumento de la actividad física es generalmente beneficiosa. La efectividad de los múltiples medicamentos disponibles está por demostrarse.
Non-alcoholic liver disease (NAFLD) is the most common liver disease in affluent societies, affecting 2-8% of the general population, and it will be soon in our societies. It is generally asymptomatic or with a no specific picture of fatigue, hepatic pain or discomfort and hepatomegaly. It is suspected in cases with aminotransferase or imaging abnormalities. Liver biopsy is considered the gold standard for diagnosis. There is a close pathogenic relationship with obesity, type 2 diabetes, hyperlipidemia, metabolic syndrome and insulin resistance. Approximately 20-25% of the cases progress into cirrhosis with all its complications including hepatocellular carcinoma and the need for liver transplantation. Correction of insulin resistance with dietary measures and physical activity is generally beneficial. The efficacy of the multiple medications available remains to be demonstrated.
