  • INTRODUCTION:

    The objective of our study was to determine whether dorsal venous complex (DVC) control technique influences positive apical margins following robotic assisted laparoscopic radical prostatectomy (RALRP).

    MATERIALS AND METHODS:

    One thousand fifty-eight patients who underwent RALRP at City of Hope from June 2007 to October 2009 were assessed. Endoscopic stapling and suture ligature of the DVC were compared. Positive apical margins were identified and compared based on DVC-control technique. Recurrence probability was estimated using the Kaplan-Meier method, and logistic regression analysis was used to predict the odds of positive apical margins.

    RESULTS:

    Of 1058 patients, 633 (60%) underwent endoscopic stapling, and 425 (40%) had suture ligature. The groups had similar baseline characteristics including age and body mass index. We observed a statistically different PSA (5.4 ng/mL versus 5.2 ng/mL, p = 0.03) and operative time (2.8 hours versus 2.7 hours, p = 0.02) between stapling and suture groups, but the actual difference was small. Operative time, Gleason score, pathologic stage, and overall positive margin rates were not significantly different between groups. Positive apical margins were observed in 39 (6%) and 27 (6%) patients in the staple and suture groups, respectively. Multivariate analysis showed that the positive apical margin rate was greater in patients with higher pathologic stage and final pathological Gleason score.

    CONCLUSIONS:

    During RALRP, there is no difference in positive apical margin rate when the DVC is controlled using either endoscopic stapling or suture ligature. However, patients with a higher pathologic stage and final pathologic Gleason score are at higher risk for positive apical surgical margins.
