Study of Post Operative Pain in Endometrial Cancer Robotic Versus Laparotomy

Prospective, Double Arm, Comparative Study for the Evaluation of Postoperative Pain, QOL, and Determination of Inflammatory Markers In Patients Undergoing Robotics Versus Open Laparotomy Approach for Staging of Endometrial Cancer

This study is being done to evaluate the efficacy of robotic approach for staging of endometrial cancer as compared to an equivalent abdominal approach. The primary objective is to measure and compare postoperative pain at rest at several time points between two groups of patients undergoing either robotic or open laparotomy approach for staging of endometrial cancer.

The primary objective is to measure and compare postoperative pain at rest at several time points (24 +/-4hours, 48 +/-4hours, and 72 +/-4hours) between the two groups of patients undergoing either robotic or open laparotomy approach for staging of endometrial cancer. Post operative Quality of Life will also be collected at several time points. The total amount of post operative opioid requirements during the first 24hours between patients undergoing either robotic or open laparotomy approach surgery. The survival status every four months for the first two years will be monitored, then every 6 months for up to 5 years. The primary endpoint is the mean difference in post operative pain VAS scores reported by subjects at rest at the following time points: 24+/-4, 48+/-4, and 72+/-4 hours between both groups after surgery has been completed.

Inclusion Criteria:

• Subjects taking NSAID(nonsteroidal anti inflammatory drug medications)within 7 days prior to baseline visit.
• Require and/or receive chronic analgesic therapy for any pain related condition
• Severe acute or chronic medical or psychiatric condition that would interfere with the study results.
