Abstract
Background and aims: endoscopic ultrasound (EUS) is a very sensitive and specific technique for the diagnosis of biliary diseases. This procedure has proven its usefulness in cases of high suspicion of biliary disease (history of gallstones and dilatation of the intrahepatic and/or extrahepatic bile ducts). We know less about its usefulness in cases of low suspicion of biliary pathology. The aim of this study was to assess the diagnostic accuracy of EUS in patients with low suspicion of biliary disease (patients with dilatation of the biliary tract were excluded). Methods: 33 patients with low suspicion of biliary disease were recruited in 12 months. All of them had no biliary findings in a previous abdominal ultrasound and computer tomography scan. All of them underwent EUS and were studied prospectively. The diagnosis was confirmed by surgery and/or by ERCP in patients with positive EUS or clinical follow-up in those with normal EUS. Time of follow-up was 9 months (range, 3-12 months). Results: seventeen patients (51.5%) presented with abnormal biliary findings on EUS (7 choledocholithiasis, 3 cholelithiasis, 2 choledocholithiasis + cholelithiasis and 5 microlithiasis). Conclusion: EUS is a useful and safe procedure for diagnosing patients with low suspicion of biliary disease.
Antecedentes y objetivos: la ultrasonografía endoscópica (USE) es una técnica muy sensible y específica para el diagnóstico de enfermedades biliares. Este procedimiento ha demostrado su utilidad en casos de alta sospecha de enfermedad biliar (historia de colelitiasis y dilatación de la vía biliar intra- y/o extrahepática). Sabemos menos sobre su utilidad en casos de baja sospecha de patología biliar. El objetivo de este estudio fue evaluar la precisión diagnóstica de la USE en pacientes con baja sospecha de enfermedad biliar (los pacientes con dilatación de la vía biliar fueron excluidos). Métodos: 33 pacientes con baja sospecha de enfermedad biliar fueron reclutados en 12 meses. Todos ellos presentaban una ecografía abdominal previa y un TAC sin hallazgos relevantes. Todos se sometieron a una USE y se estudiaron de forma prospectiva. El diagnóstico fue confirmado con los hallazgos quirúrgicos y/o con la colangiopancreatografía retrógrada endoscópica (CPRE) en pacientes con USE positiva o con seguimiento clínico en pacientes con USE normal. El tiempo de seguimiento medio fue de 9 meses (3-12 meses). Resultados: diecisiete pacientes (51,5%) presentaron patología biliar en la USE (7 coledocolitiasis, 3 colelitiasis, 2 colelitiasis + coledocolitiasis y 5 microlitiasis). Conclusión: la USE es un procedimiento útil y seguro para el diagnóstico de pacientes con baja sospecha de enfermedad biliar.
