Carbon footprint of diagnostic versus therapeutic upper GI endoscopy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is an observational study measuring the direct carbon footprint generated during upper GI endoscopy performed for dyspepsia (diagnostic) and for non-variceal upper GI bleeding (therapeutic) at two hospitals in Thailand. Investigators will record procedure duration, energy use, and disposable equipment consumption to calculate life-cycle greenhouse gas emissions attributable to the procedures themselves. Patients aged 20–80 with BMI ≤30 who undergo specified diagnostic or therapeutic endoscopic interventions are enrolled and excluded if they have major coagulopathy, pregnancy, or receive inhalation anesthesia. The study tests the hypothesis that therapeutic endoscopy produces higher carbon emissions due to longer procedures and increased use of disposables and energy.
