3D laparoscopic prostatectomy: results of multicentre study

Abstract

Abstract Introduction Three-dimensional laparoscopic prostatectomy (3D LRP) is a potentially cost-effective option for robot-assisted laparoscopic prostatectomy (RALP). Results for two-dimensional LRP and RALP are well documented; however, little has been published on the outcomes of 3D LRP. Our objective was to report the perioperative and short-term results of 3D LRP in a multicentre study. Materials and methods In total, 496 unselected men with prostate cancer underwent 3D LRP by three surgeons between December 2013 and December 2018. Median age was 64 (43–76) years. Median prostate-specific antigen (PSA) was 7.9 (0.7–148) ng/ml. Preoperative and perioperative data and complications according to the Clavien–Dindo classification were collected. PSA and continence results were reported at 3 and 12 months postoperatively. Data were analysed with IBM SPSS statistics (25). Results Pathological Gleason score was 6 in 29%, 7 in 55.4%, 8 in 9.1%, 9 in 5.2% and 10 in 1.2% of patients. Pathological tumour classification was T2c in 59.5%, T3a in 19.5% and T3b in 10.9% of cases. Positive surgical margins occurred in 27.2%. Lymphadenectomy was performed in 36.3%, with positive lymph nodes in 11.8%. Median operative time was 137 (78–334) min and median blood loss 200 (10–1100) ml. Clavien–Dindo IIIa and IIIb complications occurred in 6.9% and 1.6%, respectively. At 3 and 12 months postoperatively, 90.2% and 91.4% of patients, respectively, had PSA Conclusions 3D LRP shows promising results, comparable to similar studies published on RALP.
