New index aims to better measure bile duct infection treatment outcomes
NCT ID NCT07667166
First seen Jun 27, 2026 · Last updated Sep 01, 2026 · Updated 2 times
Summary
This study looks at medical records of 514 adults in India with acute cholangitis (a bile duct infection and blockage) who had a drainage procedure. The goal is to create a new composite index that combines factors like death, need for organ support, ICU stay, complications, hospital stay, and readmission. This is an observational study, not testing a new treatment, and aims to improve how we measure treatment success.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could give doctors a better tool to measure how well treatments work for acute cholangitis, potentially improving patient care.
- What could go wrong
- This is an observational study using past records, so it cannot prove cause and effect. The new index may not be better than existing measures.

Who is studied
Study Population * Age 18 to 80 years * Hospital admission with definite diagnosis of acute cholangitis meeting TG18 diagnostic criteria * TG18 Grade I (Mild), Grade II (moderate) or Grade III (severe) at presentation/admission or prior to drainage. * Underwent biliary drainage attempt (ERCP/PTBD/EUS-BD) or were planned for drainage (including failures with rescue drainage). * First episode of index BD in case of patients undergoing multiple episodes of index BD as per operational definitions (Technical supplement 1). * Planned repeat BD in same admission shall be considered as continuation of the index BD and all the procedural details shall be documented and analysed.

Inclusion Criteria * Age 18 to 80 years * Hospital admission with definite diagnosis of acute cholangitis meeting TG18 diagnostic criteria * TG18 Grade I (Mild) Grade II (moderate) or Grade III (severe) at presentation/admission or prior to drainage. * Underwent biliary drainage attempt (ERCP/PTBD/EUS-BD) or were planned for drainage (including failures with rescue drainage). * First episode of index BD in case of patients undergoing multiple episodes of index BD as per operational definitions (Technical supplement 1) * Planned repeat BD in same admission shall be considered as continuation of the index BD and all the procedural details shall be documented and analysed. Exclusion Criteria * Pregnant women * Missing key outcome data (minimum required: mortality status + ICU admission status + Length of stay) * Non-biliary sepsis without evidence of biliary obstruction/infection on review. * A patients with past history of BD outside the study setting (As this is akin to second episode of Index BD) * Subsequent episodes of Index BD (other than the first index BD episode) among patients with more than one episode of Index BD.
