[Robotic radical prostatectomy: overview of our learning curve].

OBJECTIVE

We present the first cases of our robotic radical prostatectomy with Da Vinci (RRPdaV) that corresponds to the learning curve (LC) of the surgeon that has initiated with this technique.

METHODS

We reviewed the first 20 patients that underwent RRPdaV, performed by an expert surgeon, without previous laparoscopic training, but with a wide experience in retropubic and perineal prostatectomy (HV). We analyzed: Surgical time, blood loss, conversion rate, intra and postoperative complications, hospital stay and days of bladder catheterization. Also: rates and location of surgical margins, as well as functional outcomes with an average follow up of 10 months.

RESULTS

Mean operating time was 140 minutes (100-211) and blood loss 180 mL (80-360), and none required a blood transfusion. There were no intraoperative complications and neither any conversion to open surgery. The only postoperative outstanding fact was mean hospital stay were 3,35 days. (3-5). We had 6 cases of positive surgical margins (30%). The most frequent location was postero-lateral. Eighteen out of 20 patients (90%) were early totally continent, 2 (10%) required the use of one pad during the first six months due slight stress incontinence that stopped spontaneously. From 20 cases, two of them (10%) had preoperative erectile dysfunction; 12 out of the remaining 18 (66.6%) preserved potency at review and 6 (33.4%) had postoperative erectile dysfunction.

CONCLUSIONS

It has been demonstrated that robotic surgery for radical prostatectomy is clearly an advantage technique (easy maneuver although it is a minimally invasive technique, comfortable and ergonomic position for the surgeon, 3D visualization and short learning curve). The RRPDAv learning curve is significantly shorter if the surgeon has a wide previous surgical experience in open and/or laparoscopic surgery.
