Eosinophilic cholecystitis: an infrequent cause of acute cholecystitis.

Eosinophilic cholecystitis (EC) is a rare disease that is characterised by eosinophilic infiltration of the gallbladder. Its pathogenesis is unknown, although many hypotheses have been made. Clinical and laboratory manifestations do not differ from those of other causes of cholecystitis. Diagnosis is histological and usually performed after analysis of the surgical specimen. We report the case of a woman aged 24 years, with symptoms of fever, vomiting and pain in the right upper quadrant. When imaging tests revealed acalculous cholecystitis, an urgent cholecystectomy was performed. Histological examination of the surgical specimen revealed eosinophilic cholecystitis. No cause of the symptoms was found.

Colecistitis eosinofílica: causa infrecuente de colecistitis aguda / Eosinophilic cholecystitis: an infrequent cause of acute cholecystitis

La colecistitis eosinofílica (CE) es una enfermedad rara caracterizada por una infiltración eosinófila de la vesícular biliar. Su etiopatogenia es desconocida, aunque se han postulado múltiples hipótesis. Las manifestaciones clínicas y de laboratorio no difieren de otras causas de colecistitis. El diagnóstico es histológico y suele realizarse tras el análisis de la pieza quirúrgica. Presentamos el caso de una mujer de 24 años, con clínica de fiebre, dolor en hipocondrio derecho y vómitos. Las pruebas de imagen evidenciaban una colecistitis alitiásica, tras lo cual se realizó una colecistectomía urgente. Los hallazgos histológicos de la pieza quirúrgica revelaban una colecistitis eosinofílica. En este caso, no se encontró causa que justificase el cuadro

Varón asiático con dolor abdominal recurrente / An asian man with recurrent abdominal pain

La colangitis piógena recurrente (CPR) o colangiohepatitis oriental es una entidad definida por la formación primaria intrahepática de cálculos biliares, cuya principal manifestación son los episodios recurrentes de colangitis, aunque también puede derivar en otras complicaciones biliopancreáticas. Se presenta mayoritariamente en pacientes asiáticos, en quienes constituye una de las principales causas de dolor abdominal agudo. El diagnóstico diferencial debe establecerse entre todas aquellas entidades asociadas a la formación intrahepática de cálculos biliares, más frecuentes en los países asiáticos frente al predominio de la colelitiasis occidental típica. Su abordaje diagnóstico y terapéutico requiere la colaboración de gastroenterólogos, radiólogos y cirujanos digestivos. Revisaremos los aspectos clínicos, diagnósticos y terapéuticos más relevantes de esta entidad que, aunque de claro predominio en países orientales, se está diagnosticando cada vez con más frecuencia en nuestro medio (AU)

Recurrent pyogenic cholangitis (RPC), or oriental cholangiohepatitis, is characterized by intrabiliary pigment stone formation, whose main manifestation consists of recurrent episodes of cholangitis, although other biliopancreatic complications can also occur. RPC develops mainly in Asian patients, in whom this entity is one of the main causes of acute abdominalpain. The differential diagnosis should be established with all other entities associated with intrahepatic stone formation, which is more common in Asian countries compared with the predominance of gallstone formation in the West. The diagnostic and therapeutic approach requires collaboration among gastroenterologists, radiologists and gastrointestinal surgeons. We review the most important clinical, diagnostic and therapeutic features of this entity, which, although clearly predominant in Asia, is increasingly diagnosed in our setting (AU)

[Role of liver biopsy in the diagnosis and management of chronic hepatitis C]. / Papel de la biopsia hepática en el diagnóstico y el control de la hepatitis C crónica.

For several years, liver biopsy has been the established gold standard for evaluating the status of liver disease in patients with chronic hepatitis C. Although this procedure continues to be recommended, current practice is changing for 2 main reasons: firstly, treatment is more effective and, secondly, biochemical and serological tests provide a great deal of information on disease progression. Pathologists can increase the importance and utility of liver biopsy in chronic hepatitis C, providing information not only on the stage of fibrosis and necroinflammatory activity but also on the grade of steatosis and iron accumulation, which are implicated in disease progression. Moreover, these specialists can identify other diseases, such as steatohepatitis and hereditary hemochromatosis. Nevertheless, the use of serological tests will reduce the indications for liver biopsy.

Papel de la biopsia hepática en el diagnóstico y el control de la hepatitis C crónica / Role of liver biopsy in the diagnosis and management of chronic hepatitis C

La biopsia hepática ha sido desde hace tiempo el patrón de referencia para evaluar el estado de la enfermedad hepática en pacientes con hepatitis C crónica. Aunque se sigue recomendando, este método se está cambiando por 2 motivos fundamentales: a) el tratamiento es más efectivo, y b) las pruebas bioquímicas y los test serológicos aportan mucha información sobre el estado de la enfermedad. Los patólogos pueden aumentar la relevancia y la utilidad de la biopsia hepática en la hepatitis C crónica, informando no sólo del estadio de la fibrosis y la actividad necroinflamatoria, sino también del grado de esteatosis y la acumulación de hierro, que están implicados en la progresión de la enfermedad. Además, pueden identificar otras enfermedades, como la esteatohepatitis y la hemocromatosis hereditaria. No obstante, con la utilización de los test serológicos se reducirán las indicaciones de la biopsia hepática
