Abstract:
Para-aortic lymphadenectomy (PAL) is a challenging procedure performed by minimally invasive surgery in very few centers, owing to its intrinsic technical complexity. We describe and assess the feasibility and learning curve of robotic double-docking transperitoneal infrarenal PAL combined with oncological pelvic surgery. Fifty patients who underwent this procedure using the Da Vinci S surgical system between March 2010 and May 2013 were included. The mean operating time for PAL surgery was 76 minutes (range, 32-150 minutes), and the mean number of lymph nodes per patient was 11.8 (range, 1-44). There were no conversions to laparotomy or laparoscopy. The mean length of hospital stay was 2 days (range, 1-25 days). Statistically significant decreases were noted for mean table rotation time (17 ± 6.8 minutes vs 13 ± 3.6 minutes; p = .02) and mean PAL operating time (85.4 ± 25.8 minutes vs 69.8 ± 24.6 minutes; p = .04) when comparing the first 20 patients and the last 30 patients. The number of nodes was similar in the first 20 patients and last 30 patients. The double-docking transperitoneal infrarenal PAL technique combined with oncological pelvic surgery is feasible, with minimal morbidity and a short learning curve.
