Assessing the carbon footprint of different colorectal surgery methods
Official title: Life Cylce Assessment (LCA) for Different Minimal Invasive Surgical Techniques: A Comparison of Robotic vs . Laparoscopic vs Open Colorectal Operation and Identification of Most Effective Carbon Foot Print Reduction Targets.
Run by University Hospital, Basel, Switzerland · NCT06844604 · Data updated 2026-11-12
This study looks at how different types of colorectal surgeries, like robotic and laparoscopic, affect the environment to see which method has a smaller carbon footprint.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 18 years old undergoing elective colorectal procedures involving bowel resection under general anesthesia.
✕Probably not a fit
Patients undergoing emergency procedures or those with ASA classification greater than III may not benefit from this study.

What this trial studies
This observational study aims to evaluate the environmental impact of robotic, laparoscopic, and open colorectal surgeries through a life cycle assessment (LCA). Researchers will analyze the materials and instruments used in these procedures, measure energy consumption, and estimate the carbon footprint associated with anesthesia. By comparing the carbon emissions from each surgical modality, the study seeks to identify opportunities for reducing the overall CO2 footprint in colorectal operations. The findings could inform practices aimed at enhancing sustainability in surgical settings.
Why it matters
Potential benefit: If successful, this study could lead to more environmentally sustainable surgical practices in colorectal operations.
How similar studies have gone: While some studies have explored the environmental impact of surgical procedures, this specific comparative approach using life cycle assessment is relatively novel.

Inclusion Criteria: * Elective operations which are routinely performed robot-assisted, laparoscopic and open: * Only Colorectal procedures involving a bowel resection will be included (colectomies (right/left), anterior resections) * General anesthesia * Aged \> 18 years * ASA classification from I to III Exclusion Criteria: * Procedures, which were uncompleted due to complications * Procedures, which switched modality (laparoscopic to open, robot-assisted to open) * Emergency procedures (mainly laparoscopic, unforeseen risk factors that lead to a change of modality, higher volume of used compressions and other materials). * Aged younger than 18 * ASA classification \> III * Vulnerable patient groups (pregnancy, patients with mental disability)
