Extraperitoneal endoscopic pelvic lymph node dissection vs. laparoscopic lymph node dissection in the staging of prostatic and bladder carcinoma.

Eighteen patients undergoing laparoscopic pelvic lymphadenectomy were compared with eighteen patients undergoing lymph node dissection performed via a totally extraperitoneal approach called extraperitoneal endoscopic pelvic lymph node dissection. Operative time, nodal yield, and hospital stays were essentially the same in both groups. However, the laparoscopic approach had a greater incidence of morbidity, leading the authors to adopt a totally extra-peritoneal endoscopic approach to pelvic lymph node dissection. Advantages of using an extraperitoneal approach are presented.
