Robotic-Assisted Laparoscopic Extended Pelvic Lymph Node Dissection for Prostate Cancer: Surgical Technique and Experience with the First 99 Cases

摘要

Background: To date, there is still a paucity of data in the literature on robotic-assisted laparoscopic extended pelvic lymph node dissection (RALEPLND) in patients with prostate cancer.Objective: To assess the technical feasibility of RALEPLND and to present our surgical technique.Design, setting, and participants: From April 2006 to March 2008, we performed RALEPLND in 99 patients prior to robotic-assisted laparoscopic radical prostatectomy. Indications for RALEPLND were a prostate-specific antigen (PSA) >10 ng/ml or a preoperative Gleason score >7. The data were evaluated retrospectively.Surgical procedure: The transperitoneal approach was used in all cases. In order to gain optimal access to the common iliac bifurcation, the five trocars were placed in a more cephalad position than in patients undergoing radical prostatectomy without RALEPLND. After identification of important landmarks, the lymphatics covering the external iliac vein, the obturator lymphatic packet, and the lymphatics overlying the internal iliac artery were removed on both sides.
