Brief Summary

Bile duct stones is a common biliary tract disease, which is characterized by high morbidity and frequent recurrence. Endoscopic retrograde cholangiopancreatography (ERCP) is an effective therapy for common bile duct stones, and endoscopic sphincterotomy (EST) which associated with recurrent cholangiolithiasis often carried out on difficult intubation or extracting stones, probably due to enhanced reflux of intestinal contents that changes the microenvironment. Patients with cholangiolithiasis were consecutively recruited and their bile was collected intra-operatively for high-throughput experiments. Pyrosequencing of 16S ribosomal RNA gene was performed to characterize the microbiota in the bile and other body fluids. A liquid chromatography mass spectrometry-based method was used to profile bile composition. Clinical manifestation, microbiome, and bile composition were compared between patients with or without recurrent of bile duct stones. The aim of our study was to identify the impact of microbiomes on the recurrent of bile duct stones after ERCP+EST therapy.
