Under low pressure with high flow, which location should be checked for CO2 leakage?

• A. All port sites for leaking CO2
• B. Check only one port
• C. No leaks
• D. Check the gas tank

Answer: (A)

CO2 leakage during laparoscopy can occur at any port when the system runs at low pressure with high flow. The combination of a porous seal and instrument movement means gas can escape through multiple points around the trocar seals. Because the flow is high, even small gaps at more than one port can push measurable amounts of gas out, so you must inspect every port site for signs of leakage rather than assuming only one location could be involved. Checking all port sites helps ensure the pneumoperitoneum is maintained and the patient stays adequately insufflated. The gas tank or regulator isn’t the source of intra-abdominal leakage during the procedure, so the focus should be on the port seals and connections, not on the gas supply itself.
