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. ? 2004 Wiley Periodicals, Inc.[SDGs]SDG3contrast medium; adult; article; carbonated beverage; case report; cholangitis; choledochoduodenostomy; cost effectiveness analysis; duodenobiliary reflux; duodenogastric reflux; echography; female; human; recurrent disease; safety; sphincteroplasty; ultrasound scanner; Abdominal Pain; Bile Reflux; Carbonated Beverages; Cholangitis; Common Bile Duct Diseases; Diagnosis, Differential; Female; Fever; Humans; Image Enhancement; Middle Aged; Recurrence; Sphincterotomy, Transhepaticjournal article10.1002/jcu.20030151241922-s2.0-2442657791
