Summary

The dorsal venous complex (DVC) control technique does not impact positive apical margins in robotic assisted laparoscopic radical prostatectomy (RALRP). Higher pathologic stage and Gleason score increase the risk of positive apical margins.

Area of Science:

  • Urology
  • Surgical Oncology
  • Robotic Surgery

Background:

  • Robotic assisted laparoscopic radical prostatectomy (RALRP) is a common procedure for prostate cancer.
  • Controlling the dorsal venous complex (DVC) is a critical step during RALRP.
  • The technique used for DVC control may influence surgical outcomes, specifically positive apical margins.

Purpose of the Study:

  • To compare the impact of two DVC control techniques on positive apical margins after RALRP.
  • To identify factors associated with positive apical margins in patients undergoing RALRP.

Main Methods:

  • A retrospective review of 1058 patients who underwent RALRP.
  • Comparison of endoscopic stapling versus suture ligature for DVC control.
  • Analysis of positive apical margin rates and recurrence probability using Kaplan-Meier and logistic regression.

Retzius-Sparing Robot-Assisted Radical Prostatectomy

Published on: May 19, 2022

Main Results:

  • No significant difference in positive apical margin rates between endoscopic stapling (6%) and suture ligature (6%) for DVC control.
  • Statistically small differences in PSA and operative time between the two groups.
  • Multivariate analysis indicated higher pathologic stage and Gleason score are predictors of positive apical margins.

Conclusions:

  • DVC control technique (endoscopic stapling vs. suture ligature) does not affect positive apical margin rates in RALRP.
  • Pathologic stage and Gleason score are significant risk factors for positive apical margins.
  • These findings aid in patient counseling and surgical planning for RALRP.
