Summary
This study identified key factors influencing endoscopic retrograde cholangiopancreatography (ERCP) duration and developed the SWEET tool for pre-procedure time estimation. The SWEET tool aids in efficient ERCP scheduling by predicting procedure length.
Area of Science:
- Gastroenterology and Hepatology
- Medical Procedure Optimization
- Health Informatics
Background:
- Endoscopic retrograde cholangiopancreatography (ERCP) duration varies significantly due to multiple factors.
- Accurate estimation of ERCP procedure time is crucial for efficient clinical workflow and resource management.
Purpose of the Study:
- To identify and describe the factors that influence the duration of ERCP procedures.
- To develop and validate a predictive tool for estimating ERCP time before the intervention.
Main Methods:
- Analysis of 74,248 ERCPs from 2010-2019 using the Swedish National Quality Registry (GallRiks).
- Linear regression and root mean squared error (RMSE) were employed to identify predictive variables for ERCP time.
- A 10-factor scoring system was developed and externally validated on 9,472 ERCPs from 2020-2021.
Main Results:
- Mean ERCP duration was 36.8 (25.3) minutes.
- Primary sclerosing cholangitis, chronic pancreatitis, hilar/intrahepatic biliary strictures, and pancreatic duct interventions significantly impacted ERCP time.
- Key procedural steps influencing duration included intraductal endoscopy, lithotripsy, dilation, and papillectomy.
Conclusions:
- The Swedish Estimation of ERCP Time (SWEET) tool was developed based on identified predictive factors.
- The SWEET tool provides a novel, easy-to-apply method for preintervention ERCP time estimation.
- This tool can guide efficient ERCP scheduling in clinical practice.
