RECRUITINGMicrobial assessment in patients undergoing to ERC with naive papilla
Coltural assessment of the bile samples obtained pre- and post-sphincterotomy during ERC in naive papilla.
Time frame: July 2022 to 2023
MDR and sentinel germs detection
Determine the presence and the prevalence of MDR organisms and sentinel germs in bile.
Time frame: July 2022 to 2023
differences in the microbial community before and after sphincterotomy.
Evaluation of differences in the microbial community before and after sphincterotomy.
Time frame: July 2022 to 2023
Identify possible correlations between pre sphincterotomy positive biliary cultures, polymicrobial population and MDR organisms with several clinical features and with laboratory signs of acute cholangitis.
