NCT05592795

Brief Summary

The objective of this observational study is to explore the structure of biliary flora in normal people, explore the dynamic impact of ERCP and EST on biliary microecology, study the marker flora, metabolites and functional genes related to biliary diseases, explore the occurrence and development mechanism, regulatory pathways and key targets of biliary diseases, and provide new strategies for the prevention and treatment of biliary diseases from the perspective of biliary microecology.

Outcome Measures

Primary Outcomes (1)

  • Successfully collect all bile samples required

    Collect the required bile samples under the required conditions according to the difference of the three groups.Then DNA extraction, Illumina MiSeq sequencing and bioinformatics analysis will be performed on the collected samples.

    1 week

Study Arms (3)

Patients with Gallbladder polyp or gallbladder adenomyosis

Patients with Gallbladder polyp or gallbladder adenomyosis In view of the difficulty in obtaining bile from normal people, our research team plans to select bile samples from patients undergoing laparoscopic cholecystectomy and patients with pathological diagnosis of gallbladder polyps or gallbladder adenomyosis as physiological bile of normal people.

Patients with choledocholithiasis

Patients with choledocholithiasis The research group plans to select bile samples from patients with first episode choledocholithiasis, patients receiving ERCP treatment for the first time, and patients undergoing duodenal papillary incision during EST operation to study the biliary flora of patients with choledocholithiasis. Compared with the normal group, analyze whether there are differences, similarities and uniqueness between the groups, dynamically track changes in the structure of biliary flora before and after treatment, and whether there is specific flora related to the type of disease, and compared with the existing biliary microbiome database, to study whether there are new bacterial species.

Other: Whether ERCP or EST is carried out

Patients with previous ERCP and/or EST operations and duodenal papilla incision during operation

Patients with previous ERCP and/or EST operations and duodenal papilla incision during operation Bile from patients who had undergone ERCP and EST duodenal papillary incision was collected, and the long-term impact of duodenal papillary incision on biliary microecology was discussed by comparing with that of normal patients.

Other: Whether ERCP or EST is carried out

Interventions

This project systematically studies the physiological characteristics of biliary microecology in normal people, and explores the impact of ERCP and EST duodenal papillary incision on biliary microecology.
