Robotic Prostatectomy Artificial Intelligence Low Pressure Pain (RALP) Trial

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. An amendment has been approved to recruit an additional 60 participants, total overall recruitment is 100.

Exclusion Criteria:

* Patient participation in a different investigational clinical study within 90 days before screening and for the duration of this trial (unless previously approved by the investigator and Sponsor);
* Patients requiring any surgical procedure in addition to Prostatectomy and or / Pelvic Lymph node dissection

* Immunocompromised such as that resulting from chronic oral steroid use, chemotherapeutic agents, or immune deficiency disorders;
* Any medical condition which precludes compliance with the study
* Subjects with any other clinically significant unstable medical disorder, life threatening disease, or conditions that, in the opinion of the investigator, may jeopardize the subject's well-being and/or the soundness of this clinical study or which would contra-indicate a surgical procedure.
