摘要：
A system for performing an endoscopic surgical procedure in a surgical cavity of a patient that includes a multi-lumen tube set including a dual lumen portion having a pressurized gas line and a return gas line for facilitating gas recirculation relative to the surgical cavity of the patient, and a single lumen portion having a gas supply and sensing line for delivering insufflation gas to the surgical cavity of the patient and for periodically sensing pressure within the surgical cavity of the patient, a first gas sealed single lumen access port communicating with the dual lumen portion of the tube set and a second valve sealed single lumen access port communicating with the single lumen portion of the tube set.
