Risk score to predict biliary leakage after elective liver resection

Area of Science:

• Hepatobiliary Surgery
• Surgical Oncology
• Gastroenterology

Background:

• Biliary leakage is a significant complication following liver resection, impacting patient morbidity.
• Previous studies on posthepatectomy biliary leakage (PHBL) had limitations in power, homogeneity, and validation.

Purpose of the Study:

• To develop and validate a reliable risk score for predicting severe PHBL.
• To identify key predictors of severe PHBL in patients undergoing liver resection.

Main Methods:

• A multicentre observational study involving 2218 patients undergoing liver resection.
• Patients were randomly assigned to development (n=1475) or validation cohorts.
• A multivariable analysis identified predictors and a risk score was developed and validated.

Main Results:

• Severe PHBL occurred in 4.1% of patients.
• Predictors included significant blood loss, prolonged ischemia time, specific anatomical resection planes, and staged hepatectomy techniques.
• The risk score demonstrated good predictive performance in both development (AUROC 0.79) and validation (AUROC 0.70) cohorts.

Conclusions:

• The developed risk score accurately predicts severe PHBL after elective hepatectomy.
• This multi-institutionally validated tool aids in identifying high-risk patient subsets.
• The score can inform clinical decision-making and patient management strategies.
