title: Sonographic demonstration of duodenobiliary reflux with soda enhancement.
abstract: Cholangitis rarely occurs after sphincteroplasty if there is no biliary obstruction. We report the case of a patient who developed recurrent cholangitis despite having a patent biliary tract after sphincteroplasty. Duodenobiliary reflux was demonstrated on sonography after enhancement of the reflux flow with a novel oral contrast agent, a carbonated soda beverage. Sonography with contrast enhancement provided by soda solution may prove satisfactory to detect duodenobiliary reflux after sphincteroplasty safely, effectively, and economically.
