Microbial profile of biliary tract infection in patients undergoing therapeutic endoscopic retrograde cholangiopancreatography (ERCP), and baseline risk factors predicting microbial growth and post-ERCP cholangitis

Abstract Introduction: Stasis of bile flow can result in microbial colonization of the biliary tree. Cholangitis is a common adverse event linked to endoscopic retrograde cholangiopancreatography (ERCP). Aim: To establish the bacterial profiles isolated from the bile sample and to evaluate the pre-ERCP risk factors predicting the microbial growth and development of post-ERCP cholangitis (PEC). Material and methods: This was a prospective cohort study, which was conducted at the Department of Hepato-gastroenterology, SIUT from 1 January 2021 to 31 December
