Purpose: We evaluated the feasibility of robot-assisted laparoscopic radical cystectomy (RARC) with pelvic lymph node dissection (PLND), especially extended PLND (ePLND), during our initial experience with this technique.
Materials and Methods: From August 2007 to March 2009, prospective data were obtained from the 21 consecutive patients who underwent RARC with PLND at Korea University Hospital. Data included baseline characteristics, perioperative variables, pathological outcomes, and complications. Evidence of the lymph node yield curve was examined by using linear regression to compare the number of lymph nodes obtained.
Results: Among 21 patients who underwent RARC, 13 had ileal conduit urinary diversion and 8 had orthotopic neobladder. Standard PLND (sPLND) was performed in the first 15 patients, and ePLND was performed in the more recent 6 patients. The mean total operative time was 515.5±145.1 minutes, and the mean estimated blood loss was 346.8±205.9 ml. The mean time for PLND was 106.7±25.2 minutes in patients with ePLND and 72.1±14.1 minutes in patients with sPLND (p=0.001). All patients had negative surgical margins. The mean number of retrieved nodes was 23.5±12.8 (range, 8-50) in all patients: 38.6±10.8 (range, 29-50) in ePLND and 15.7±12.2 (range, 8-21) in sPLND.
Conclusions: Perioperative data and oncologic features showed that RARC with PLND is feasible. Robot-assisted laparoscopic surgery is a safe and effective procedure with acceptable morbidity and good oncologic results from the viewpoint of PLND, especially ePLND.
