A Rare Case of Spontaneous Gastrobiliary Fistula Diagnosed by Oral Contrast-enhanced Ultrasound

Abstract

We report the case of a 55-year-old man with a spontaneous fistula between the intrahepatic bile duct and stomach.Oral contrast-enhanced ultrasound (CEUS) was used in this patient and made the diagnosis of fistula as observed during open surgery. We found that oral CEUS should be considered as a safe, simple and effective method to diagnose and evaluate gastrobiliary fistulas.
