Brief Summary:
The AirSeal® System will allow for lower CO2 absorption rates than the Xcel® System. Furthermore, lower variance in pneumoperitoneal pressure will allow for less "over-pressure" events and peritoneal stretch, which may reduce postoperative pain.

Condition or disease Intervention/treatment Phase
Prostate Cancer Pneumoperitoneum Device: AirSeal System Device: Standard Endopath Not Applicable

Detailed Description:
The primary observation to be made is the level of PaCO2 in the arterial blood, specifically when the patient is insufflated and deflated during the surgery. As a result of the consistent pressure that the AirSeal® system maintains, CO2 will be absorbed in lower levels when compared to the standard of care systems in which fluctuations in intra-peritoneum pressure are seen. Therefore, higher pressures will result in higher levels of CO2 exchange in the blood, leading to increased vasodilation and lower pH levels.

Arm Intervention/treatment
Active Comparator: AirSeal System
This group receives the AirSeal System for intraoperative insufflation.
Device: AirSeal System
To analyze the results of patients randomized to either the AirSeal system or Standard Endopath trocar.
Other Name: Valve-free Trocar

Active Comparator: Standard Endopath
This group receives the Standard Endopath Trocar for intraoperative insufflation.
Device: Standard Endopath
This group receives the Standard Endopath Trocar for intraoperative insufflation.
Other Name: Endopath Trocar

Primary Outcome Measures :
  1. Intraoperative pneumoperitoneal pressure (mmHg). [ Time Frame: Through Day 1 post-op ]
    Compare the maximum intraoperative pneumoperitoneal pressure (mmHg), smoke evacuation quality (categorical), and overall operative times (minutes) between the conventional and valve-less trocar groups.
