Brief Summary
The 'Robotic Prostatectomy Artificial Intelligence Low Pressure Pain Study Trial' aims to assess the feasibility of being able to review operative outcomes such as pain when comparing two commonly used surgical devices for the removal of prostate cancers. The data collected will inform methodologies for future, larger, multi-center trials investigating pain in patients undergoing prostate cancer surgery. A robotic prostatectomy is a commonly performed surgery used to treat prostate cancer by removing the prostate gland. In order to perform the procedure, the surgeon must 'inflate' (technical term pneumoperitoneum) the patients abdomen with carbon dioxide gas using a device called an insufflator. Adequate 'inflation' of the abdomen ensures the surgeon can clearly visualise the prostate. Unfortunately, higher pressures of abdominal 'inflation' are a large contributor to intra and post-operative pain in patients having prostatectomies. The type of insufflator device used to maintain inflation pressures in the abdomen are thought to be a variable contributing to differing levels of intra and post-operative pain. Therefore, the purpose of this trial is to compare intra and post-operative pain when using two different insufflator devices when performing robotic prostatectomies. Both insufflators are already commonly used across multiple NHS Trusts. 40 patients awaiting a robotic prostatectomy at the urology department at the Lister hospital, Stevenage, will be randomised to use either the Conventional Insufflator System (CIS) {Stryker PneumoClear Insufflator} or the AIRSEAL® Insufflation System (AIS) to 'inflate' their abdomens during their prostatectomies. Data relating to various intra and post-operative outcomes will be collected in the 30 days following the patient's operation. Outcomes include levels of intra and post-operative pain, medication use, procedure time, recovery room time, length of hospital stay, post operative nausea and vomiting and adverse events. This data can be analysed to identify trends in differences in outcomes between the AIS and CIS insufflators.

Study Arms (2)
Stryker PneumoClear insufflator
ACTIVE COMPARATORMeasuring patient's pain during and after a robotic prostatectomy using the Stryker PneumoClear insufflator. 20 patients will be randomised and assigned to this arm of the trial. Post-op pain outcomes will be compared to the control arm (standard of care), the AirSeal Insufflation System.
AirSeal® Insufflation System
NO INTERVENTIONMeasuring patient's pain during and after a robotic prostatectomy using the AirSeal® Insufflation System. 20 patients will be randomised and assigned to this arm of the trial. This device is the standard of care at the Lister hospital, Stevenage, UK.
Interventions
40 patients randomised to two arms will undergo robotic prostatectomies using either the control AirSeal® Insufflation System (AIS) or the intervention Stryker PneumoClear Insufflator. Intra-operative and post-operative pain will be compared between the two arms of the trial.
