Comparing the Environmental Impact of Endoscopic Ultrasound and Magnetic Resonance Cholangiopancreatography in Adults with Suspected Choledocholithiasis

What this Trial Is About

Researchers are investigating the environmental impact of two procedures, Endoscopic Ultrasound EUS and Magnetic Resonance Cholangiopancreatography MRCP, used to detect common bile duct CBD stones in patients with an intermediate risk. Both methods are diagnostically similar, but MRCP is energy-intensive and requires large facilities, while EUS consumes less energy and allows for same-session treatment procedures, potentially lowering repeat visits. This study aims to measure and compare the carbon footprints of these diagnostic techniques to support more sustainable healthcare decisions. The study observes patients who are scheduled to undergo either EUS or MRCP as part of their evaluation for suspected CBD stones. Participants are grouped based on the diagnostic method they receive, with no experimental treatments assigned. Data on the total carbon dioxide equivalent emissions per procedure will be collected over a 12-month period to assess the environmental impact of each imaging method. Participants will be monitored during their diagnostic procedure, and researchers will track the carbon emissions associated with the use of EUS and MRCP. The main outcome measured is the total kilograms of CO2 equivalent emitted per procedure. This observational study will also record emissions over the year to understand the environmental footprint better, helping guide future choices in diagnostic methods for this condition.
