Robot-assisted laparoscopic radical prostatectomy: perioperative outcomes of 1500 cases

Abstract

Background: Robot-assisted laparoscopic radical prostatectomy (RALP) is an evolving minimally invasive treatment of for localized prostate cancer. We present our experience of 1500 consecutive cases with an analysis of perioperative outcomes.

Patients and methods: Fifteen hundred consecutive RALPs were performed by a single surgeon (VRP). Following Institutional Review Board approval, clinical coordinators performed prospective intraoperative and postoperative data collection. Functional outcomes were assessed using validated self-administered questionnaires.

Results: Mean OR time from skin incision to fascial closure (the time that the surgeon was present) was 105 minutes (55-300). Mean EBL was 111 cc (50-500). Ninety-seven percent of patients were discharged home on postoperative day 1. The overall complication rate was 4.3% with no mortalities. The positive margin rate (PMR) was 9.3% overall. PMR was 4% for pT2, 34% for T3 and 40% for pathologic stage T4.

Conclusions: Our initial series represents one of the largest published series for perioperative outcomes of robotic assisted prostatectomy. Our data demonstrates the feasibility, safety and efficacy of the procedure.
