Microbiota analysis with next-generation 16S rDNA gene sequencing in recurrent common bile duct stones

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is the main remedy for gallstones, but the postoperative recurrence rate is high. Recent research has indicated that the biliary microbiome takes part in the pathogenesis of cholelithiasis. However, it is not yet known whether biliary microbiome dysbiosis is relevant to recurrent cholelithiasis.
