Rate of Duodenal-biliary Reflux Increases in Patients With Recurrent Common Bile Duct Stones: Direct Evidence From Barium Meal Examination
In Brief
An observational study evaluating standard barium meal examination for Common Bile Duct Gall Stones and Common Bile Duct GallStones. Completed, enrolled 64 participants across 1 site.
Detailed Summary
ERCP is the primary choice for removal of common bile duct stone (CBDS) currently. However, 4-24% patients underwent recurrence after successful clearance of CBDS. Stone re-formation due to chronic inflammation of biliary duct is generally considered an important cause of CBDS recurrence, which is associated with duodenal-biliary reflux (DBR) after sphincterotomy. Although it was believed that DBR was the important cause of CBDS recurrence, the direct evidence was still lacking. Here we conducted a case control study to investigate the DBR rate in patients with recurrent CBDS after ERCP.
