Evaluating the success of different biliary drainage procedures

Defining the Clinical Success of Different Percutaneous Transhepatic Biliary Drainage Procedures

Theresienkrankenhaus und St. Hedwig-Klinik GmbH · NCT05268731

This study is testing if measuring GGT levels after a biliary drainage procedure can better show how well the treatment worked compared to looking at bilirubin levels, helping doctors make better decisions for patients.

What this trial studies

This study analyzes the clinical success of percutaneous transhepatic biliary drainage (PTBD) procedures by measuring serum bilirubin and gamma-glutamyl transferase (GGT) levels in patients post-procedure. It involves a systematic review of medical records from patients who underwent technically successful PTBD over a 20-year period. The study aims to determine if GGT levels can serve as a more reliable indicator of success compared to bilirubin levels, potentially influencing patient discharge times and improving comparisons with other drainage methods.

Who should consider this trial

Good fit: Ideal candidates are adults who have undergone a technically successful percutaneous transhepatic biliary drainage procedure.

Not a fit: Patients who have not had a technically successful PTBD will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved assessment of biliary drainage procedures, enhancing patient outcomes and discharge processes.

How similar studies have performed: While the approach of using GGT as a success indicator is novel, similar studies have shown the importance of alternative biomarkers in assessing treatment outcomes.
