Summary
Single-site multiport robot-assisted radical prostatectomy (ssmpRARP) is a feasible and safe extraperitoneal technique. This approach demonstrated comparable short-term outcomes to conventional multiport RARP, including faster bowel activity return.
Area of Science:
- Urology
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Robot-assisted radical prostatectomy (RARP) is evolving with single-site techniques.
- Single-site multiport RARP (ssmpRARP) offers a minimally invasive alternative.
Purpose of the Study:
- To describe an extraperitoneal ssmpRARP technique using the da Vinci Si® platform.
- To compare ssmpRARP with conventional multiport RARP (cmpRARP).
Main Methods:
- Retrospective analysis of patients undergoing RARP for localized prostate cancer (June 2020-January 2022).
- Propensity score matching was used to compare 18 ssmpRARP patients with 18 cmpRARP patients.
- Key outcomes including operative time, blood loss, complications, and recovery were analyzed.
Main Results:
- Demographics were comparable between the 18 matched ssmpRARP and 18 cmpRARP patients.
- Total operative time, blood loss, pathological data, early outcomes, and costs were similar.
- The ssmpRARP group showed significantly faster return to bowel activity (p=0.016) with no difference in complication rates.
Conclusions:
- Extraperitoneal ssmpRARP using the da Vinci Si® platform is feasible and safe.
- Short-term outcomes are comparable to transperitoneal cmpRARP.
- Further prospective trials and long-term follow-up are warranted.
