title: Does changeover by an experienced open prostatic surgeon from open retropubic to robot-assisted laparoscopic prostatectomy mean a step forward or backward?
abstract: We assessed whether changeover from open retropubic [RRP] to robotic-assisted laparoscopic prostatectomy [RALP] means a step forward or backward for the initial RALP patients. Therefore the first 105 RALPs of an experienced open prostatic surgeon and robotic novice-with tutoring in the initial 25 cases-were compared to the most recent 105 RRPs of the same surgeon. The groups were comparable with respect to patient characteristics and postoperative tumor characteristics (all P > 0.09). The only disadvantage of RALP was a longer operating time; the advantages were lower estimated blood loss, fewer anastomotic leakages, earlier catheter removal, shorter hospital stay (all P < 0.04), and less major complications within 90 days postoperatively (P < 0.01). Positive surgical margin rates were comparable both overall and stratified for pT stage in both groups (all P < 0.08). In addition, an equivalent number of lymph nodes were removed (P > 0.07). Twelve months after surgery, patient reported continence and erectile function were comparably good (all P > 0.11). Our study indicates that an experienced open prostatic surgeon and robotic novice who switches to RALP can achieve favorable surgical results despite the initial RALP learning curve. At the same time neither oncological nor functional outcomes are compromised.
