Live Surgery for Laparoscopic Radical Prostatectomy—Does it Worsen the Outcomes? A Single-center Experience

Objective: To compare outcomes of laparoscopic radical prostatectomy (LRP) performed in live surgery versus daily routine LRP. Methods: From January 2014 to June 2017, data from LRP performed at our Institution in live broadcasting by 3 experienced laparoscopic surgeons during educational events were collected. A 1:2 matching (according to BMI, comorbidities, NCCN risk groups, and operating surgeon) was performed with the routine LRP patients collected in our prospectively-maintained database. Chosen procedures were performed within the same time span by the same surgeons. Data of interest were compared. Results: Twenty-three live surgery LRPs were analyzed (Group A). Forty-six matched patients were the controls (Group B). Groups were comparable at baseline. No differences were found in perioperative data (operative time, blood loss, and intraoperative complications, 4.3% in both Groups) and postoperative complications. Particularly, 10 (43.5%) and 22 patients (47.8%) did not report complications (Group A vs B, respectively, P = .54). The majority of complications were Clavien 1-2, with 2 patients per Group requiring blood transfusion. Overall positive surgical margins rate was 26.1%. It was significantly higher in Group A (43.5% vs 17.4%; P = .02), but no differences were found in the number of patients who relapsed, who needed radiotherapy or androgen deprivation therapy within a median follow-up of 25 months in both Groups. No differences were found regarding functional data. Limitations include a low sample size and limited follow-up. Conclusion: LRP has similar perioperative outcomes when performed in either live surgery or daily routine setting. We underline the higher positive surgical margins rate after live surgeries that should increase the awareness before embarking on it.
